I have a new DIR-655: H/W Ver. B1; F/W Ver. 2.00 NA
It is solid as a rock to my wired computers, but the Internet connection (not the wireless signal) to my wireless devices (laptops and smart phones) occasionally drops out for several minutes, many times each day. It is not necessary to reset my router to reconnect; after a while wireless Internet returns on its own. I upgraded from another D-Link router and never had this problem. In my judgment the problem appears to be the router. Does anyone know why the wireless Internet connection might disappear and then reestablish itself?
I used an app on my smart phone to select Channel 11. No neighbors have routers close to this channel. My cordless phones are DECT (1.9 MHz). My microwave oven does not cause this dropout.
The DIR-655 wireless settings are pretty standard:
- WPA personal security mode
- WPA mode is Auto (WPA or WPA2)
- Cipher is TKIP and AES
- Group key update interval is 3600 seconds
- 802.11 mode is mixed n and g
When this wireless Internet connection dropout occurs, the router's signal strength does not decrease; the Internet connection just disappears. Time after time I have confirmed that the integrity of the Internet connection remains solid on my wired computers and disappears only from my laptops and smart phones.
I have checked the wireless spectrum when the wireless Internet connection disappears. There is no other signal, e.g., no neighbor's router on my channel (11), and the strength remains at 5 bars.
Could this be a defect in my router, or is this a known problem with this model? I have set up many routers and have never experienced this type of problem. Anyone have any suggestions? Or should I just return the router -- and stay away from another DIR-655? Thank you.

Try manual channel instead of auto scan. If you do have some neighboring Wifi routers near by, it's probably some interference wit the other routers and its making the 655 stop and it has to rescan for a open or clearn channel. Try 1 or 6.

I am the original poster of this thread, “New DIR-655: wireless Internet occasionally drops out.” Today I made a interesting discovery, and I am fairly confident that I have determined the cause of my problem, which is random loss of Internet connection on Wi-Fi. My suspicion is something called bufferbloat. To keep these comments reasonably brief, you can read an explanation of bufferbloat on Wikipedia (see http://en.wikipedia.org/wiki/Bufferbloat.) In short, the article says “bufferbloat is a phenomenon in a packet-switched computer network whereby excess buffering of packets inside the network causes high latency and jitter, as well as reducing the overall network throughput. This problem is caused mainly by router and switch manufacturers making incorrect assumptions about whether to buffer packets or drop them. As a general rule, packets should not be buffered for more than a few milliseconds. While latency has been identified as more important than bandwidth for many years, the falling price of RAM encourages the use of larger buffers and exacerbates the problem.” It goes on to say “on older routers, buffers were fairly small so filled quickly and therefore packets began to drop shortly after the link became saturated, so the TCP protocol could adjust, and the issue wouldn't become apparent. On newer routers buffers have become large enough to hold several megabytes of data, which translates to 10 seconds or more at a 1 Mbit/s line rate used for residential Internet access. This causes the TCP algorithm that shares bandwidth on a link to react very slowly as its behavior is quadratic in the amount of buffering.” (My DIR-655 was purchased new in Feb. 2012).
There is a very interesting article on this topic in the Association for Computing Machinery, which includes a discussion on this subject with several experts, including Internet pioneer Vint Cerf, that you can read at http://goo.gl/efD6b.
I’m leaning toward returning my new router and going back to a less sophisticated router. Anyone have any suggestions for a rock-solid wireless N router – not a new DIR-655?
P.S. In my original post I said my cordless phones operated at 1.9 MHz. Of course that should be 1.9 GHz.
-
I would return the router or call up DLink support and ask them for help.
Good luck.

Hmmm. I have an older H/W version (A3) and recently have had this exact same issue crop up. Wireless clients drop internet, but not local LAN. Wired clients hum along just fine. I notice because I see my VPN drop on my laptop. Sometimes it comes back on its own, but sometimes I'm impatient and just reboot the DIR-655.
W925, what gives you suspicion about this "bufferbloat" problem? And why does it only effect the wireless clients and not the wired? I came here looking for upgrade advice, thinking my DIR-655 was about ready to give up the ghost. For years, I had my cable modem stacked on top of it, not aware of the heat problems I could've been causing. I only noticed the heat being generated when the router started dropping a while back (4 or 5 months, probably).
Another interesting sidenote: I was in the admin interface (from a wired computer) this morning when the wireless signal dropped (as evidenced by the VPN dropping on my laptop). The admin interface also hung. I'm still leaning towards a hardware issue.

wireless925,
Without getting into bufferbloat (or anything else design specific), I have a very similar issue with my 655 (B1, FW 2.03). I use it as a wireless access point and gigabit switch. The wired switch works rock solid, but I get random hard dropouts on the wireless the require a power cycle to the 655. I've had the wireless drop out when a laptop is no more that 10' away from the 655 and in the same room (no walls to go through). I've performed a lot of the troubleshooting steps including selecting the channel manually; 1, 6, 11, etc. I've experienced this with several wireless laptops and devices so I'm fairly certain it's related to the 655. And, I'm interested in wireless N as the protocol; as opposed to G or other.
I've yet to find a way to keep this from happening, and not interested in spending much more of my limited time troubleshooting this much further as I sense this will become somewhat of a "snipe hunt."
Was wondering if you purchased another wireless router and if so, if it solved your random wireless connection problems.

Thanks furry. I'll check that this weekend, but I live in a corner house on our street. The room the 655 is in is in the front/center/non-neighboring side of the house. Assuming that the closest house has wireless on, then I would guess that it would be no closer than 60 feet to my 655 (and through interior and exterior walls). Even if it were the same wireless device and on the same channel, etc., is it realistic to the that it could cause a drop to a connection with a device that's located in the same room? Also, and I should have mentioned this previously, when my 655 drops a wireless connection, when I try to re-establish the connection I no longer see the 655 as an "available" network. it's no longer on the wireless list when the laptop or other device scans for wireless connections, and doesn't reappear until I power cycle the 655. This is why I think it's a 655 device issue irrespective of neighboring wireless devices. And, my 655 has a unique name so I don't think there's any confusion with the SSID (which is is always broadcasting).

Any cordless house phones?
Does a wired PC also loose connection to the router and internet when the WiFi goes down?
Maybe someone can review your router settings with you using teamviewer (http://www.teamviewer.com) if your interested. Its safe and secure.
-
tjkaz- I've just bought a new 655. Didn't want the hassle of recreating all the config customizations. I'll get all posted on whether that fixes my issue.
Although I did also add another wireless access point on the other side of the house. I tested turning off the wireless on the 655 and the remote signal (in my home office, same place where the 655 is) is strong enough for my laptop to switch over seamlessly. Not sure if in my 655 failure scenario (loss of IP, but still a strong wireless signal) would cause my wireless client to switch over. If it does switch over, I'll never know if the issue is fixed.
Ah, heck- I'll wait a couple days before putting the new 655 in to see if my VPN drops...

Thanks again furry. Yes, I have a wireless phone - it's DECT 6.0 which is supposedly 1.9GHz. The 655 is 2.4ish, so wouldn't think there's an issue there.
As I posted originally, the gigabit switch on the 655 is rock solid. Even when the 655 needs to be power cycled so I can get the wireless working again, there's no issue with the wired switch.
Once again, even if there was interference by another wireless router or a wireless phone, would it make sense that the 655 drops the connection AND is no longer discoverable/available to any other wireless device until a power cycle??
Thanks again for the help.

tjkaz,
There are several users here experiencing the exact same problem with their RevB 655's. I've had this happen to mine a couple of times since I installed it last December. To my knowledge, nobody here (or at other forums) has found the cause of the 'wireless' radio just quitting for no apparent reason. My symptoms are just as yours, the wireless signal just disappears until the router is power cycled (I haven't tried a software reset, easier to just pull the plug). Wired connections are not affected.
If you do happen to find a cause/solution, please be sure to come back here to share your experience. I'm sticking to my 655, cuz mine only fails every so often. My wireless activity is limited too, so it's easier to live with.
-
So, I have this same issue. I had this same issue on my Netgear, but thinking it was my router being old, I went out and bought the 655. Same thing. Here's the kicker. I moved a month ago, so when I setup my new network I did it using the brand new router. I tried increasing the group key to max, and so far that I have not lost my wireless connection. I will know soon though, and I don't think that should do anything to fix it?

Hi, I came across this string while searching why my DIR-655 (HW: A1/A2 FW: 1.21) started dropping wireless clients when I closed the lid of my laptop to let it sleep. 9 wireless devices all dropped at the same time and then slowly reconnected.
I checked the router’s log and found, "...disconnected for reason: Authentication Failed", for each device. The entry just before those was from my laptop, "...UDP timeout:-1 'Teredo'". So I searched for that meaning and did some experiments based on my findings. Disabling IP v6 did not solve it, but it did allow a Skype entry to appear in the log as a timeout. I tried exiting Skype first before letting the computer sleep and it seems to have stopped the wireless client dropping. I re-enabled IP v6 and it still was OK. So, if Skype was ever running when my laptop computer went to sleep, all wireless clients lost connection.
Now this is an assumption on my part, but it seems the router is resetting the wireless connection in an effort to keep from losing the Skype connection. Could it be Skype, or my laptop, is not communicating correctly to the router that it’s sleeping and the router gets confused and performs a wireless reset? Maybe this issue is somehow common to others in this thread.
I will pursue the Skype issue further and repost to this thread if anyone responds with interest to my efforts and conclusions.

I would also make sure that the one devices WiFi drivers are up to date if there are any.
I would recommend that you completely power OFF and unplug any power adapters and batteries if you can, from all devices and let them sit for 1 minute. Then power them back up and test.
Turn off WiFi security temporarily on the 655 as a test to see if the behavior persists.
Disable any and all 3rd party security SW on the devices as a test.
How many other WiFi routers are near by?
Has a factory reset been performed?

Fuzzy, I looked at buckyswider's reply #10 and I did not pickup on what you were referring to. I am running only the DIR-655, no extenders, and I have a Motorola SB5101 on Comcast. There are other wireless networks, but none over 2 bars. My mobile phone is Dect 6.0
I did just install the latest 6/3/12 15.2.0.19 drivers for my Intel Centrino Advanced-N 6205 Wi-Fi adapter. Then tested by closing the lid. My son's xBox stuttered, but did not kill the game. I tried again with Skype off and no effect at all to the game. I'll try the power cycling and other power suggestions when my boys are off xBox Live.
Below is a portion of Tuesday's log that starts with my laptop sleeping and ending with (top) my son's MacBook Air losing connection. I noticed Skype (on my laptop) and my laptop show different ports.

Oops. I meant port #14, sorry. Please try some of the suggestions there and let us know what the settings are and if any of the suggestions help.
Please review the form sticky about ComCast DNS since you have ComCast.
-
Haha, definitely wasn't me offering helpful advice :) .
Now that this is bumped, I guess I should finally followup on my issue. The (old) router kept intermittently dropping; I replaced with the new DIR-655 and all is well. So it seems like it was definitely a hardware issue. I almost bought another new one just last week, since I was having routing issues that I couldn't figure out and I remembered about this past hardware flakiness. that one ended up being an "interesting" fix that I should post in another thread for discussion's sake...
-
Please post what you did to resolve your routing problems...
-
Fuzzy, I performed a "paper clip" factory reset and then restored to my saved config.
So far my sleep tests do not effect other wireless clients' connections.
Seems to be solved, thank you!
The forum sticky about Comcast DNS has a link to nowhere, so I was unable to follow up with that.
Now if I could just get the SharePort to work, all could be good. Is there a post thread for that?
-
Glad the factory reset and restore config worked.
I see that ComCast has changed there web site and seems the link to that DNS Opt Out form is now broke and no longer working. I'll look in to this and see if I can get the link updated. It had to do with something similar to Dlink Advanced DNS services. I think ComCast has something going on with routing DNS traffic thru there services and this was inpacting how DLink routers were working on this particular ISP. The link recommended that users could disable there DNS help services on a web site so any and all DNS traffice was handled normally with out any additional DNS routing help which seemed to be effected how DLink routers were working when connected to ComCast systems.
I'll see if I can find the info.
What version of SP are you using? What devices are you trying to use with SP? Have you installed SP v4 yet?

Fuzzy, thank you for the DNS fix link. I will check it out when I have some time.
BTW, I am using OpenDNS.org for DNS filtering if that impacts anything here.
SharePoint is v4.11 downloaded from the DIR-835 link in your new version post.
My test was a SanDisk 1GB ThumbDrive and an old HP PSC 1210xi USB printer.
I was testing on mine before I attempted setting up my father's for a shared printer.
He is out of state and I access his network with TeamViewer, so I wanted a dry run.
Glad I tried on mine first, because nothing showed up in the SharePoint view window.
-
I suggest if possible, Power OFF the router and USB device your trying to connect. Plug in the device and power it one, then power ON the router and let it boot.
Temporarily disable any 3rd party Firewall programs while testing. Reboot the PC that SP is installed on while the router comes to ready. Then run SP. The router should be detected and see along with attached USB device.
Ensure the PC has a reserved IP address on the router as well.
The router is still using v1.21 FW?

Furry, I unplugged the router and attached my SanDisk Cruzer 1GB thumbdrive, then plugged in the router. I woke up my laptop and ran SharePort 4.11, still could not see the drive. I disabled Windows Firewall and Microsoft Security Essentials, still could not see the drive. For kicks, I changed the "My plug of USB type is:" to WCN Configuration and rebooted the router, ran SharePort, still could not see the drive.
No other security is on my computer. The router is HW A1 and FW 1.21. When I click the firmware Check Now button, it reports I have the latest version from 2008/10/09 The thumbdrive is not running any login security, it opens right up when plugged into my laptop. All devices on my network have reserved addresses and the address range is set to only those devices.
-
Do you still have the installation CD for your router by chance? You might want to un-install v4 and install the version that came with your router. Seen various issues with people trying to use SP on v1.xx FW. I know my Rev B router with 2.xx FW works pretty good with SP v4. Unfortunately that version wont upgrade an Rev A router, sorry. ::)

Hello all. I'm new to this forum. I've owned the DIR-655 for a few years now. I have the latest FW (2.10) and Hardware Version B1. Until recently, the DIR-655 has been rock solid. However, recently I've experienced the SAME issues as everyone on this forum. My wireless connectivity drops for unknown reasons. The wireless signal is still there (I can see it with inSSIDer), but all PCs disconnect and indicate "identifying network". Oddly, Android phones and iPhones sometimes remain connected, but my Windows Vista, 7, and 8 laptops lose connections. I usually have to unplug the router to get it to come back on. This is frustrating!!! I've tried messing with all settings and all the suggestions made thus far. The one thing I haven't tried is the factory reset. Is that the only solution to the above problems???
PS: Has anyone experienced a problem with the LAN cables not "clicking in" to the LAN ports on the DIR-655? Some of my LAN cables will not click in and sometimes fall out. Any solutions to this problem?

Oddly, Android phones and iPhones sometimes remain connected, but my Windows Vista, 7, and 8 laptops lose connections. I usually have to unplug the router to get it to come back on. This is frustrating!!! I've tried messing with all settings and all the suggestions made thus far. The one thing I haven't tried is the factory reset. Is that the only solution to the above problems???
PS: Has anyone experienced a problem with the LAN cables not "clicking in" to the LAN ports on the DIR-655? Some of my LAN cables will not click in and sometimes fall out. Any solutions to this problem?

What region are you located? Somerset, MA 02726
Has a Factory Reset been performed? No, reluctant to lose all my settings.
What FW version was previously loaded? v 2.07
What was the reason for updating to v2.10? New is better than old, I guess. Is the 2.10 FW D-Link published not good? If so, why was it published?
Was the router working before the update? Sporadic problems of the same nature
What ISP Service do you have? Cable or DSL? Cable (Comcast)
What ISP Modem do you have? Stand Alone or built in router? Motorola SurfBoard SB6121
What ISP Modem make and model do you have? Motorola SB6121
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems. Does not apply.

Thanks for replying. My replies to your questions are above. There are no conflicting cordless phones in the house.
I've tried all your suggestions and changed all the settings that you suggested. I've tried channel 1, 6, 11 and auto select. Right now, it seems stable on channel one, but I have no hope it will stay connected. I've turned off wireless encryption too. But, as you know, the wireless will eventually disconnect for (as you know) unknown reasons. I think there is a serious problem with D-Link DIR-655 routers since it appears many others have the same problem and all the same suggestions DLink supplies do not seem to fix the problems we are all having with D-Link routers.
Now what?

Most routers work well out of the box. Most problems users see are in mis-configurations and external environment conditions that effect the router. I have this router and have tested other users routers to ensure the HW is working well with success.
Any other WiFi routers in the area? Use InSSIDer to find out. How many?

Furry, I located my original install CD. It did not contain any version of SharePort, because the DIR-655 HW A1 - FW 1.0 did not originally have SharePort. My FW 1.21 has support for SharePort, but is that only for HW A2?

You might get a hold of DaveVT here on the forums and ask him if SP works for his Rev A 655. He's one of the few I know that has a Rev A model. Not sure if he's using SP right now however I Think he's got the last FW version for Rev As. I don't want to have you update to v1.35 before we can check to see if SP will work with that version. If he recommends updating and SP works with v1.35, then go for it. Ask him first and get his opinion. I only have a Rev B and use SP v4.

Hi again and thanks for the reply. Since yesterday afternoon, I've lost wireless connection 4 times (3 times while working at home today). I am now connected via LAN cable at work so I don't lose wireless connectivity.
Please review this: FW Update Process<=I did and followed closely.

Can I restore all my settings after a hard reset? Will the firmware be reset to the original?
Honestly, this is very frustrating for a customer to have to go through all this to resolve a problem.
-
Do a factory reset then setup the router from scratch.
-
Factory reset completed and rebuilt from scratch.
The wireless connectivity is now WORSE than it was before!!! Computers (Vista, 7, and 8) are all connecting and disconnecting randomly. I'm am wired to the router right now on a Windows 7 machine. Cannot connect wirelessly! However, phones are connected.
Also Teamviewer link takes me to a download page to download software. Who is connecting to me and how?
The Comcast DNS issues link you supplied is a dead link.
Very frustrated!

Update: The "Enable Channel Scan" was set to enable. This may have been causing the issue (I've indicated this selection doesn't work for my network). I have no encryption set-up. Seems to be up right now. I will keep pumping wireless connections tonight and tomorrow and then will post an update. :-\
I'm on channel 6. The only other network my PC identifies is a wireless G on channel 1. I'll keep on channel 6 for now.
Do you think encryption has anything to do with this? Just curious....
-
Did you have encryption setup before?
Try w out tuen try w WPA and TPIK then try WPA2 w TPIK.
-
Yes, I had WPA2 encryption before all these issues. I removed it during troubleshooting.
Right now, I'm up for about 2 hours on wireless on channel 6 with several PCs and phones. My signal is between -50-60 dBm amplitude. The closest router on channel 6 is at about -90-95 dBm amplitude. Seems channel 6 is clear.
I'll post tomorrow with an update.
-
Ok. Keep us posted.

Disconnected again! :'( After about 2 hours and 15 minutes, the windows 7 and Vista machine disconnected. The XP machine stayed connected. I had to unplug the router to get the network back up. It is now back up and running.
Here are some of the log entries from just prior to disconnect:

I'm at a loss. I'm thinking this router is what is known in the router industry as garbage. I would think D-Link would offer to help me on the phone versus this forum. I'm not a happy customer.

One thing you can try, disable IPv6 on the 7 and Vista PCs under there networking adapter settings.
If anything, if this is the Rev B router we might try to down grade the FW from 2.10 to 2.03 or .07.
If the XP PC is working and the other 2 are not, I might presume someone on those 2 PCs is not configured write.
Also we might have someone review the routers settings with you using teamviewer. It's a remote control access program that is safe to use with another person.

Ok, well, you could update and see if that helps. Just know that you cant downgrade back to v1.21 after.

Update: I tried the suggestion to disable IPv6 on the Windows 7 and Vista machines. Did not have any impact on losing wireless connections. I've already tried to go back to FW 2.07 and that also did not have any impact. Same results no matter what I do!
I just lost wireless connection at 10:52AM ET on the XP, 7, and Vista machines AT THE SAME TIME. I checked the modem and it was still up and running for over a day, so this was the DIR-655 router that dropped wireless. Nothing was contained in the router log. It simply stopped broadcasting the wireless signal!
Yesterday, I lost connection three times during the day (XP, 7, and Vista machines AT THE SAME TIME). Nothing was contained in the router log. It simply stopped broadcasting the wireless signal!

Hi,
Well I don't think it's a Dlink - Router problem, this issue can happened with any router brand IMHO.
I experience the same problem (WAN drops only not LAN) when generating high traffic like playing online (Ie: World of Warcraft) or doing intensive web site request. I'm still investigating.
For myself, I observe a "1014 DNS Client Event: Name resolution for the name xxx timed out after none of the configured DNS servers responded." in the windows event log. You can see in Control panel\Administration\Event viewer\System if the connection drop is following a 1014 DNS Client Event.
Here what causes i'm investigating so far:
- TCP/IP Offload is enabled for a network adapter
- TCP/IP v6 is enabled and ISP's does not yet support TCP/IP v6.
- The spanning tree “portfast" setting is not enabled on your servers switch ports.
- Router and PC communicating on different channel or standard.

Question to Furry:
I'm curious about the first potential cause mentioned above which is the TCP Offload. I know that the DWA-552 does not support TCP Offload, but the fact it is enabled by defaults in Windows 7 / Vista, can this have an effect on the present issue?
Thanks

Thank you for posting the good information.
We've found by experience on here with users that most of the wireless problems dealing with improper operation and sporadic connections with WiFi is usually having to deal with more than a few other neighboring WiFi routers near by using up all the channels and AUTOSCAN and the programming behind it, has to stop and try to find another usable channel. This seems to find one for a time, however even at some point, even if the channel is used by another router at a longer distance, the channel is still being used and there is interference on the channel. So again the AUTOSCAN function kicks in and stops the connections. All this seems to be happening on the 2.4Ghz frequency as more and more people acquire WiFi routers and devices and in higher populated areas like a apt complex or metro areas. There are lots of WiFi and congestion in these areas and not enough channels to handle them all on 2.4Ghz. So as users complain about the problems with there HW here on the forums, we try as best as we can to figure out the problems and see if we can help alleviate the problems however most of the problems are not HW related persae, most of the problems are external conditions as mention above. In these cases we recommend switching to the 5Ghz freqency with other WiFi routers and adapters as this frequency isn't as crowded.
I'm sure there are some other conditions as you mentioned that can effect any Mfr router, networking and the like. As for TCP OFF Load, I would presume this could also be an issue, to what extent, I don't know. I would presume that most Home and or Small business products may or may not support this OFF LOAD option as the average home user would not have any such needs or use for it. Maybe. I would think that a Mfr would want the easiest end user experience for that product line and not have to deal with such options that may be used at higher levels of networking that might be seen more in bigger business or enterprise class networks. By the looks of it, TCP OFF LOAD would be handles at the OS or LAN NIC level and seems to be mainly used on 1 and 10 Gb networks. So I presume that WiFi and any thing less than 1Gb shouldn't be effected by it.
TCP/IP Offload (http://en.wikipedia.org/wiki/TCP_offload_engine)
My 2 cents.

Musart: Thanks for the info. I looked at the system event viewer for the time I had the wireless drop for three computers at the same time (reviewed on the Vista machine). There was nothing logged at the time I lost connection! It did log my reconnection to the network a few minutes later, however, it did not log the reason the connection was lost at 10:52AM. Weird.
-
Tnb:
Indeed weird, surprised that windows did not log anything. I'm not at home right, but I will post a screenshot tonight to make sure that we look at the same screen in the event log, there are so much page to look.
Furry:
Interesting facts. I was to buy a new DIR-655 with HW B (there is a rebate now at BestBuy in Canada) to be able to updgrade to the 2.10NA FW for IPV6 support since I only have the HW A version which can only be upgraded to 1.35NA. I thought that might be an issue...
Also, I was thinking of the packets size management when playing online games, there is so much streaming information in a short time that I was thinking that a setting might be set to better manage the data flow.
But I'll test the channel settings. If I understand, on some occasion, the router might intentionally drop the connexion to do a channel rescan when set to AUTOSCAN isn't it? I thought it was only at the initial connexion.
I might look at the DIR-825 which support 5g but the DWA-552 cards does not support 5g and my cordless phone are on DECT 6.0
As I soon as I get some infos on my findings, hopefully positive, i'll post them.
Thank for the support.

IF you get the Rev B router, Please do not update to v2.10. Please run the Rev B router. IT's not always necessary to upgrade FW. Run the router out of the box first to see.
For gaming, review this:
Gaming and QoS for XBL (http://forums.dlink.com/index.php?topic=42011.0)
If you look at the 825, there are other 5Ghz alternatives for adapters, DWA 160, 182 and DAPs that can go 5Ghz.
Are the DECT phones on 5Ghz? Can you find the specific freqency?

@tnb: Sorry I can't find a way to upload a picture...

Ok, then shouldn't bother 5Ghz.

This shouldn't bother using a 2.4ghz router-Wireless card neither.
Anyway, I'm trying some setting you suggested on post #5 (One by one, btw). One of my concerns is DNS Relay was OFF, so I'm trying it ON now.

Never use NTP but I've just set the ntp1.dlink.com to see if it's works over time.

To Furry and all posters,
I've read this string and I see one important consideration is missing, HEAT! When I first bought my DIR-655 HW A1 back in 2005, it dropped connections all the time. I exchanged it for another at the store and the new one dropped too! Then it dawned on me that where it sat on my closet shelf, with the modem flat on top, was not allowing enough air circulation. (Linksys products were designed to stack in those days) So I wall mounted it where it was clear of any air flow blockage. Problem solved! I suggest that the posters with extreme connection dropping problems reposition their router and even try a small fan directed at it to see if that makes a difference, because it did for me.
-
Good catch Hi-Def.
I should have posted this sooner as well:
Link>Wireless Installation Considerations (http://forums.dlink.com/index.php?topic=48327.0)
Ambient room temp could play a role however usually it shouldn't.
Any chance if you posting temp numbers?
I know that the DIR-857 is being effected by temp heat.
Anyone try the Wireless Consideration as a test and see if this helps. I do run one of my routers like this in my bedroom. Works well.
-
Good points here.
But keep in kind that is a WAN issue I observe, not LAN. Meaning that no wireless connectivity is lost, just Internet connectivity.
So far, I've test Multicast Stream ON (was off) => Still have connectivity drops on high traffic so this is eliminated.
Now, I've disable the IPV6 protocol in Windows since the DIR-655 A4 doesn't not support it, I observe a lot of " UPnP renew entry 255.255.255.255 ... UDP timeout:-1 'Teredo' " in the log. So, I'll see in a couple of days.
Feedback to come.
-
We've see it were some routers don't support IPv6 and new OS's do and are enabled in the OS by default. Disabling IPv6 in the OS seems to help.
-
Follow-up:
With IPv6 disabled I got two WAN drop during the night (about 40 minutes between the the drops)
I immediatly observed in the log: Blocked outgoing ICMP packet (ICMP type 3) from ... to .... on each occurence. On the two occurences, they are right at same time as the drops but I can't figure out if it's preceding the WAN drop or it's following it...
Will try other settings tonight.
More feedback to come.

I too am having the SAME exact symptoms as everyone else has replied with the router. I've tried every solution given, and still no luck. I'm starting to think the router is defective, it was at first working wonderful when out of the box, then a few months down the road it just started disconnecting on wireless; the wired is solid as a rock too, no disconnects on that end.

Hi,
I have had my DIR-655 for a long time. About a month ago this issue started happening randomly. It is really bad. My internet connection drops constantly. Sometimes I have to power cycle the router and other times I think it eventually comes back up. What is causing this problem? The other access points in the area have really weak signals and are in different channels than mine. I checked using a wifi analyzer. And the wired connection works flawlessly. It is just the wireless that randomly drops internet. This router has worked solidly at two different houses over the past years but now within the past month it decides to randomly drop internet connections. What is causing this?

No, the hardwire PC is perfectly fine, as if it was connected straight to the modem, never one disconnect, and online game play does not lag at all...the wireless pretty much does not connect at all at this rate.

Furry, DaveVT31 replied he does not use SP.
UPDATE: I loaded firmware v1.31 (the next step up from my v1.21) and SharePort works now! Note the "Check Online Now for Latest Firmware Version :" button never reported a newer version while I had v1.21. Now v1.31 will report v1.32 is available when I click that button. Maybe that should be reported to the firmware server's webmaster.
FW v1.31 also cured my wireless clients' connection drop everytime I closed the lid to sleep my laptop. Seems the router no longer resets the wireless in an attempt to keep from losing my Intel Centrino Advanced-N 6205 adapter's connection as it goes to sleep. All is good now, at least with my DIR-655 A1!

Glad thats working well for you. Ya, v1.35 is the latest and should be reporting that however they may have wanted it to report that way as to graduate the version instead of directly going to the latest.
I recommend that you keep what is loaded for now and see how it goes.
Keep us posted.
Enjoy.
UPDATE: I loaded firmware v1.31 (the next step up from my v1.21) and SharePort works now! Note the "Check Online Now for Latest Firmware Version :" button never reported a newer version while I had v1.21. Now v1.31 will report v1.32 is available when I click that button. Maybe that should be reported to the firmware server's webmaster.
FW v1.31 also cured my wireless clients' connection drop everytime I closed the lid to sleep my laptop. Seems the router no longer resets the wireless in an attempt to keep from losing my Intel Centrino Advanced-N 6205 adapter's connection as it goes to sleep. All is good now, at least with my DIR-655 A1!
