Title: DIR-615 Hard wire disconnects
Post by: obliox9 on January 30, 2013, 06:32:31 AM
I am a new user of the DIR-615, it was a gift from a friend. I have had a rock solid internet connection for many years using a linux box as a firewall and router. Recently I decided to try netflix and replaced my linux router with the DLink DIR-615.
It was very easy to set up.
Every day or two I find that I have been disconnected from the MUD I play, and also folks get disconnected from the chat server I run. This had never happened before.

I have read the forums and have tried the following that I found in the forums as provided by FuzzyNutz:

Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can copy and paste these from under Status/Device Info/Wan section.
Turn off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices on the router.
Ensure devices are set to auto obtain an IP address.
   note: my chat server is a debian linux box and is set for fixed ip address my other
   two boxes..XP and Ubuntu 12.04 LTS are auto dhcp. All boxes are set in DIR-615 as
   reserved ips
Set Firewall settings to Endpoint Independent for TCP and UDP.

One thing I do notice is that at times (like now) all the hard wire link lights blink repeatedly (about once a second), all at the same time. I am sure this is not correct. The lights should only blink when there is activity.

This problem shows up on average about once  a day.
My best uptime lasted 2 days and then all hard wired machines disconnect.
I have had one disconnect on the wireless Roku device I have hooked up.

I am not sure what to do, this seems such an odd problem. I doesn't seem to matter whether or not it is wired or wireless.

Also, before retiring I was a network administrator for a small ISP so I am fairly familiar with how things should work?

Does anyone have any ideas on what I should try next? I like the product and would hat to have to go buy a different manufacturer. My cable provider (COX cable) recommends Netgear.

Thanks you.

No, I didn't want to have to set up the network all over again

What ISP Service do you have? Cable or DSL?
Cox Cable as stated in my original post

What ISP Modem make and model do you have?
Cisco DCP 3010

I am not using any wireless equipment other than a Roku player.

Any cordless house phones? yes, one on my desk.

Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
yes, 9 others...they are all on channels 1 or 3 or 6. My info says channel 6+10??
my signal strength is very good, all the others are -70dbm mine is -10dbm

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Currenly I am only running linux boxes, XP is off for now..so no firewall or anti virus stuff running.

It seems to me that the Dlink should NOT reboot or reset it self by itself. I am going to monitor the log files or perhaps there is a place where I can monitor the uptime of the router. I am not sure whether it is actually rebooting itself or just dropping all my connections for just a sec or two.

Based on your response I have changed my wireless channel to 11. I don't think this will solve the problem of the router disconnecting me or rebooting itself if that is what it is doing.

Thank you for the prompt reply.

Firmware Version :      3.11NA , Tue, 23, Jun, 2009 and router states this is the latest version.
v3.13 is available:
FIxed Blackberry RIM connectivity issue.
Support DLink DNSSEC Spec.
Add SMTP Server Port
Which includes fixes from:
3.12   Fixed: “User” access issue.
Fixed: Wireless connection issue.
Fixed: DHCP reservation issue.
Fixed: Static IP issue.

Let see if some troubleshooting and suggestions help resolve this first before updating FW.

What region are you located?
Arkansas

Has a Factory Reset been performed?
No, I didn't want to have to set up the network all over again
Save off the current router configuration to file, then try a factory reset and do a basic setup and configruation of the router. Test it and see what happens. Then load the Configuration file and test again.

What ISP Service do you have? Cable or DSL?
Cox Cable as stated in my original post

What ISP Modem make and model do you have?
Cisco DCP 3010
I don't think the 615s do Gb speed on the WAN port however you might set a manual WAN port speed of 100Mb and see what happens.

Setup DHCP reserved IP addresses for all devices ON the router. Including the debian server.
Did that already.

It is hard to do since I use my computers for work. Currently only my Ubuntu and Debian boxes are hard wired to the router.
Test two the two PCs online and all others off if you can. This might help to narrow down if something is causing the problem.

What wireless modes are you using? Under Setup/Wireless/Manual.
Mixed 802.11n 802.11g 802.11n
I recommend using Mixed G and N only if you dont have any devices using B mode any more. Most current devices mainly use G and or N.

What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support
Security Mode is WEP
I am not using any wireless equipment other than a Roku player.
WPA2 and AES only is preferred and is more secure and has best performance.

Any cordless house phones? yes, one on my desk.
Is it 2.4Ghz by chance? It's best to keep all other devices away 3-6 feet from routers.

Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
yes, 9 others...they are all on channels 1 or 3 or 6. My info says channel 6+10??

Hopefully by you chancing to 11 will keep your WiFi going. You maybe hitting a WiFi congested area on 2.4Ghz. Keep an eye on the amount of other Wifi routers near by, if you seem to see alot of issues or problems with WiFi on your router, you'll need to upgrade to a 5Ghz router and adapters.

Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Currenly I am only running linux boxes, XP is off for now..so no firewall or anti virus stuff running.

Only reason we can figure out why routers reboot is that there is a problem and they are having to stop and reboot due to something on the line is not right, or stop and try to change channels due to WiFi interferences.

Based on your response I have changed my wireless channel to 11. I don't think this will solve the problem of the router disconnecting me or rebooting itself if that is what it is doing.

Thank you for the prompt reply.

Keep us posted.
Title: Re: DIR-615 Hard wire disconnects
Post by: obliox9 on January 30, 2013, 09:00:04 AM
Thanks. I just had a disconnect while trying to post here.

The Dlink kept blinking away..just like everything was ok, except it dropped all my connections both wireless and wired. This is extremely frustrating.
I had to physically power the box down and back up to get it working. The other times I have seen this problem, it has been overnight, and when I come to my desk in the morning, my stuff is disconnected, but I can reconnect without a power down/up. Not sure why that is so.

So changing the wireless channel did NOT solve the issue.

It seems pretty difficult to make all those changes you recommend at one time and see if there is any difference...so for now I have done the following:

>I don't think the 615s do Gb speed on the WAN port however you might set a manual >WAN port speed of 100Mb and see what happens.
It is set for 10/100 I have set it for 100mb

>I recommend using Mixed G and N only if you dont have any devices using B mode >any more. Most current devices mainly use G and or N.
I have set it to mixed G and N only

I will wait and see what happens with these changes
If these don't work, then I will go ahead and do a factory reset and also change the wireless security at that time.

I currently have only my 2 linux boxes hard wired to the dlink. The roku player is also online.
I also have a wireless card in the XP box, and an ethernet card so I can use it either way but it is off for now.

Thank you

One thing to try for this test, turn OFF the WiFi radio. See if the wired connections still drop or not.

Keep us posted.
Title: Re: DIR-615 Hard wire disconnects
Post by: obliox9 on January 30, 2013, 09:08:29 AM
ok I have turned off the wireless stuff for now
I will keep you informed of my progress. It might take a day or so to find out.

Thank you for helping me.

ps I looked up the specs on my phone, here they are:

The Advanced DECT1580 cordless phone operates on the newly released 1.9GHz frequency band.
So I don't think the phone is interfering.
Title: Re: DIR-615 Hard wire disconnects
Post by: FurryNutz on January 30, 2013, 10:24:52 AM
Ok, phone shouldn't be a cause of interference however as a test, try to move the phone as far away from the 615 router as possible to be sure.

Keep us posted on the progress.
Title: Re: DIR-615 Hard wire disconnects
Post by: obliox9 on January 30, 2013, 10:39:49 AM
The phone has to be on my desk, which is in my dedicated computer room. It is 8ft away, as the crow flies. I can try and have my incoming line rewired, but I don't think that should be necessary to get this working.

As an aside, I used to have a linksys BEFW11S4 plugged in to my switch and used it as an access point for when friends came over. It worked flawlessly. My linux box did the DHCP and firewalling, the linksys did the wireless.

The only reason I removed it and started using the Dlink was that I could not get the Roku player to work with it, even after working tirelessly with the Roku support staff. Now that I have removed the linux box I suppose I could also remove the Dlink and then use the Linksys as my router, instead of just an access point. That would be an interesting test if I get really frustrated. I could also put my old setup back and try and use the Dlink as the wireless access point.

Again, thank you for helping me, I really appreciate it.
Title: Re: DIR-615 Hard wire disconnects
Post by: FurryNutz on January 30, 2013, 10:50:32 AM
Ok, 8ft should be good then, DLink recommends 3-6ft.

Is the Switch still connected to the 615 or is everything connected to the switch? Just want to be sure the switch isn't introducing any problems either. If it's connected,  I would remove the switch as well and directly connect to the 615 to test.

Seem some issues with Roku. Is the Roku wired or wireless to the 615? I presume the Roku worked on the previous router before?
Title: Re: DIR-615 Hard wire disconnects
Post by: obliox9 on January 30, 2013, 11:20:17 AM
I apologize, I didn't mean to be confusing.

OLD SETUP
-------------
Cable modem --> linux box --->switch
switch had 3 computers connected to it and the linksys
Linux box did DHCP and firewalling. Linksys did the wireless for when friends visited and brought their laptops or smart phones.
Worked perfectly for many (10+) years.

When I got the Roku player I had problems. It would find my wireless network but would not log onto the local network side. I never used passwords since I was using MAC address filtering. I worked very hard with Roku to solve the issue, including trying to use passwords,  but could not. The linksys was an old unit and no longer supported by Cisco.

So, I had the DLink that I had received as a gift so:

NEW SETUP
--------------
Cable modem -->Dlink router -->
currently 2 computers connected via ethernet and wireless radio off.

I really like the way the Dlink operates...port forwarding is working great. Reserved IP seems fine. The web interface is very intuitive and easy to use, especially if you turn off QoS. I would like to be able to keep using it, and would really regret having to put back my old setup, but I will if I have to.

Hope this helps you understand both my old and new setups.
Thanks so much

Wish more users would post there information like you do. LOL
Really helps us here to kind of get an over view of users network systems.

So using the Roku now, is it connected wired or wireless to the 615 when you have it connected? Have you tried the Roku with the 615 at all yet?
Title: Re: DIR-615 Hard wire disconnects
Post by: obliox9 on January 30, 2013, 12:04:58 PM
Thanks for the nice compliment, after working for many years in the isp and with people, I understand the importance of good information.

I have used the Roku with the Dlink wireless and it works pretty good. It has disconnected once while playing a Netflix stream, but it works excellently when running. I currently have wireless radio turned off.

My current connections are:
Debian irc server with myself and one other connected.

Ubuntu personal box:
3 instances of Mudlet running, one for each character.
XChat connected via ethernet to Debian irc server
Firefox web browser for google mail and Dlink Forums

Thank you.

Title: Re: DIR-615 Hard wire disconnects
Post by: FurryNutz on January 31, 2013, 07:08:45 AM
And this is with ALL wired devices connected?

Ok, seems like we have narrowed down some here. Wired router only seems to be working for you.

I would now turn on the WiFi radio and use InSSIDer application to see who's around you and find a clear and open channel if one is available. You said before that there are a few near by and channel 11 was open at the time? Try setting the router to 11 if it's still open and set mode to Mixed G and N. I presume you have devices that use G and N modes?
Title: Re: DIR-615 Hard wire disconnects
Post by: obliox9 on January 31, 2013, 07:20:58 AM
Yes, this is just for wired devices...wireless has been turned off.

I didn't want you to have to just sit and wait.....
I have to drive over to to the Walker Heart Institute in Fayetteville this morning
to pick up a friend and bring him home. I will post back once I return.

The only devices I have that are wireless are the Roku Player and my old XP box which is both wireless and ethernet. I will have to check and see what type it is.

Should be back in about 6hrs or so

Ok 5pm CST  back home.

Turned on the wireless radio, set it to  mixed N & G, lets see what happens. I have not turned on the Wi Fi Protected status yet.

Just did a doublecheck, there are apparently more wireless units in my neighborhood than I thought..and 11 looks busy so I decided to make a change to channel 5 which no other unit is apparently on. My inSSIDer shows me at 5+9, whatever that means. Also auto channel scan is off.

Currently have my XP box connected as of 5pm.

Thanks

PS Just turned on the Roku player, it works good.

6:39pm Dlink dropped all connections.
Had to unplug and restart the router to get back wired and wireless connections.
Uptime: 1 1/2 hrs.

Any suggestions?
Title: Re: DIR-615 Hard wire disconnects
Post by: FurryNutz on January 31, 2013, 05:53:40 PM
I'm wondering if your area is WiFi congested on 2.4Ghz. Won't really know this unless you can take the 615 to a different location, say a friend or families place and connect it there. I don't think upgrading would even help. We've kind of narrowed down that with out the WiFi running, the wired router is stable. Turning on WIFI, the router becomes unstable and drops connections probably use to many WiFi in the area and using up channels and being near or on the same channel.

You could turn down the output power under Advanced/Adv Wireless from high to low and see if that helps some.

I would like to see if you could try this in a different location if possible.

The only other thing I can suggest is that you turn off the 2.4Ghz WiFi and get you a 5Ghz AP and a couple of 5Ghz WiFi adapters for those devices you can upgrade to 5Ghz.  ::)
Title: Re: DIR-615 Hard wire disconnects
Post by: obliox9 on January 31, 2013, 06:41:53 PM
Thanks for the respone, I will try and turn down the power on my next test.

I don't know of anyone around that would have the ability to insert this into their own network and use it. My friends are all on windstream dsl. Most don't have the knowledge or the desire to test things out.

I have been watching the various wireless networks and yes, there are a lot of them around. most have very low signal strength to me. My XP box is about 1ft away from the router, and my Roku player is about 15ft with no obstructions or walls.

I have used the inSSIDer and watched all the signals and none seem to disappear, the only one that does that is mine, when the router drops all connections. None of the other networks are on channel 5. Most are on 1, 6 or 11.

You mentioned in a previous post about a possible upgrade to the firmware?

Update:
I have noticed that over the past few hours that the wireless connection to my xp box has been dropped but not the wired connections.
Title: Re: DIR-615 Hard wire disconnects
Post by: FurryNutz on January 31, 2013, 06:56:10 PM
Yes you could try upgrading FW. Again, upgrading FW will probably not solve anything since you seem to have a lot of other WiFi routers near by, upgrading FW will not solve the problem of other WiFi being and using up the channels. I do believe that the best solution for you would be to switch to 5Ghz. Being in an area with other WiFi routers and using up the channels is becoming more problematic in areas with more population as everyone is getting into buying WiFi routers.

I have read about the open source WW-DRT software. Many folks have reported that similar problems have disappeared after upgrading/switching to the open source software, do you have any opinions, either officially or unofficially?

So far just the one instance of the dropped connection so far.
The WinXP box with both ethernet and wireless seems to get dc'd when using the
wireless ( ethernet is unplugged). It seems to only last 5-10 min before dropping.
The wired connections have not dropped.

I have yet to try turning down the power on the radio. Also I was wondering about
location. I have the router sitting on top of the chat server and only about 1ft away from the XP box with the wireless card in it. I would not think that it would make much of a difference, but I do have a bit of latitude on where I place the Dlink.

I do find it strange that mine seems to be the only signal on the inSSIDer that seems to disappear.

Thanks so much for trying to help me, I really appreciate the excellent support even though I have not solved my problem.
Title: Re: DIR-615 Hard wire disconnects
Post by: obliox9 on February 01, 2013, 07:04:30 AM
Just another update.

I believe the WinXP disconnects are machine specific since it drops the wireless to it but not to the Roku player.

So far no more wired disconnects, and I have been playing with the Ralink turbo wireless card configuration in XP to see if I can solve that problem.

I have (as of 7:30am) moved the Dlink router off of the chat server box. Will keep you posted.

Thanks

I have read about the open source WW-DRT software. Many folks have reported that similar problems have disappeared after upgrading/switching to the open source software, do you have any opinions, either officially or unofficially?
DLink doesn't officially support WRT FW on any of there routers. I some cases it has resolved some issues, mainly people wanting other options like bridging and such. WRT might help resolve some of this however again, keep in mind that you have other WiFi routers near by and regardless of what FW is loaded, would probably not help. Also be aware that WRT is a bit more complex to use and has a lot more advanced features than you normally would see on these routers. I loaded it on a NG router I had a few years back. It is nice however even for me, I thought it was a bit too complex.

Also we are dealing with something called "Good Neighbor Polilcy" set down in stone by the WiFi organization for all Mfr to have there routers play nice near other routers. This is the main reason why your router isn't working well on WiFi. Since others are near by and using up channels, it's programmed to stop when this kind of interference is encountered so that it wont interfere with others. Now your nieghbors routers, should have this same policy, however some older routers did not thus they can be just like big bullies on the block, broadcasting a signal that any other router just can't deal with. And since we don't know what your neighbor routers are, made and model, kind of hard to tell.
So far just the one instance of the dropped connection so far.
T
he WinXP box with both ethernet and wireless seems to get dc'd when using the
wireless ( ethernet is unplugged). It seems to only last 5-10 min before dropping.
The wired connections have not dropped.

DLink recommends placing of WiFi routers 3-6 feet away from other electronic equipment.

I do find it strange that mine seems to be the only signal on the inSSIDer that seems to disappear.

Thanks so much for trying to help me, I really appreciate the excellent support even though I have not solved my problem.

You could attemp to at least update to the most current version on DLink web site and do some more testing. I think we figured out that there is a more resent one available for your Rev. If you do decide to, please follow this: FW Update Process (http://forums.dlink.com/index.php?topic=42457.0)

You might try a different WiFi adapter in that XP PC to see if it helps. Glad that your making progress.

24hrs later after relocating the Dlink - no hard-wire disconnects. 
I was getting disconnects on the XP box using it's wireless card so I turned it off and
disconnected it from my network. So far so good. Roku player works excellently.
I have yet to turn down the power.

Hoping for continued excellent performance. The router works really great when it runs correctly!

Next test, another 24hrs .. then I will reinsert the XP box via ethernet cable and see how that works.

Unfortunately, I had 2 hard wire disconnects right at the end of my test on the 48th and 49th hours. I really thought it was fixed. Oh well. I guess I will have to find a different router. Roku does not have a dual band capability.

You could attemp to at least update to the most current version on DLink web site and do some more testing. I think we figured out that there is a more resent one available for your Rev. If you do decide to, please follow this: FW Update Process (http://forums.dlink.com/index.php?topic=42457.0)

I continue to try and get the DIR_615 to not have disconnects. The best I have done so far is 2 days 2 hrs before it randomly disconnects both wired and wireless lan connections. I have managed to capture some debug log info and have posted it below.
I also know I can update the firmware, but have chosen to not do it yet. Is there anything in this that can help you understand why these disconnects occur? I can understand if there is a wireless conflict to reset the wireless part, but do not understand why it would ever drop a wired connection.

It looks to me like this might be the culprit.

Any chance you can gain access to the ISP modem logs? Might be some info here. I would contact the ISP service provider and ask them if they can see any thing on there side and with the modem logs during this time frame when this happens.


I would do the FW update and see if that changes anything.

Pretty unlikely that Cox Internet would give me access to their log files.
Can you tell me what dhcpc sent restart signal to rc means?

The ISP modem should have it's own logs and might be accessible. Try accessing the ISP modem at 192.168.100.1

Possible that there was an issue between the modem and router and thats a code that gets reported. I don't have any detailed information on what the log entries mean.

Maybe someone at Dlink could answer the question as to what the log entry means?
It would be nice to understand what the log debug info is telling us before doing the upgrade.
Also, 2 questions about upgrading:
1. Can I use firefox from my Ubuntu 12.04 LTS machine or do I have to do it from a firefox on the Xp machine?
2. I copied the instructions for the upgrade down, because I won't have internet when I do this..is there a page on what to do if the upgrade doesn't work and the router fails to come back?

Download the files you need before starting the upgrade. Disable all 3rd party security SW like anti-virus programs temporarily. Do this over a LAN wired connection only. Follow those instructions. I recommend setting up from scrach after the last Factory reset. I would even disconnect the ISP modem cable too.

Thanks so much for the information, I really appreciate it.
Last question, then I won't bother you for a few days at least. :)
I have not yet exhausted all the options you originally gave me, there is still the
hardreset back to factory defaults. If I do this, or the FW upgrade, is there a default password to get back into the web based interface?

One more thing, in the upgrade info it states:
If you're upgrading from minor to minor version, reloading of the configuration file shouldn't cause a problem.
If I go from 3.11 to 3.13 is that a minor to minor so I can use the previous config file or should I redo from scratch?

This time I want you to set up the router from scratch after the final factory reset has been performed. I want a clean update and slate on the router to see if we can get this going with out disconnects.

Hello Fuzzy:

Sorry for not posting here sooner.
Status:

Have yet to perform the upgrade.  I debated back and forth, and I have downloaded all the upgrades, downgrades etc and web pages for instruction.

I am not yet convinced that the cause is the firmware. My current up-time is
6days. It seems fairly stable so I am wondering if I was just being attacked by the script kiddies in the neighbourhood. Being the new router on the block, who knows.

The D-Link performs brilliantly when it runs. I enjoy using it as it is easy to configure and monitor.

I promise to keep you posted as to my progress and I apologize for not doing so sooner.

Ok man. Just checkin on ya. Seems like we might have helped the router work a bit better. Let it run as is. I wouldn't upgrade FW. Should work well. Keep us posted when you can.

Enjoy.

Uptime now almost 8 days. Small problem however...I can no longer get to the admin gui at 192.168.0.1
I have been able to access fine, and have just let it run for days now. Had to do a kernel update and after
I closed the page and rebooted my Ubuntu machine, I could no longer access the page. My XP box is also unable to get there. Any ideas on what to do?

I sure hate to do a hard reset now that everything is working fine.

Shouldn't have to do a hard reset, however you could just power OFF for 15 seconds and back on. Odd that the UI is not accessible though.

Update: After watching and waiting, I finally believe that the issue may be diagnosed correctly. Over the past month or so, I have had these random disconnects. Originally, because I had installed the new D-Link router I thought the issue was something to do with it. However, after watching everything, and especially the past 2 weeks when the disconnects got worse and worse, I saw my modem reset itself. I called Cox Internet and they sent the techs out. Three service trucks and a van showed up and they found some serious line interference on the run that feed my house and others. They will begin testing and fixing the line noise. I belive that once that is done, the d-link will be fine, without a firmware upgrade.

Fuzzy: I will keep you posted. I can say there is value in watching, waiting and observing rather than just running out and changing something.

Well hello again! I was hoping not to have to post here but I thought I would give
an update on my situation, especially since the folks here on the forum have been so helpful.

I have no clue as to whether or not Cox has actually fixed the line, however my modem is no longer resetting itself.

I have gone ahead and done a firmware upgrade to v3.13 and that seems to have fixed the issue of my all my connections dropping off and also some of the router lockups and me having to yank the plug on it. Not sure if that issue is actually solved but will continue to monitor it. I am very hopeful that it is.

As for my random disconnects goes...they still have persisted. They mostly show up when I play a MUD game, which of course is basically a fancy telnet session. I use mudlet which is a fine client. After careful watching and waiting, I finally discovered that it seems to disconnect every 10 minutes if I am in a situation where no data passes the connection. I searched around in the manual and found this:

Under Firewall Settings:
NAT Endpoint Filtering - Endpoint Independent - Any incoming traffic sent to an open port will be forwarded to the application that opened the port. The port will close if idle for 5 minutes.

I have tested this extensively over the past week and can confirm that idle ports are closed after 10 min. By idle I mean no data passes over the session in either direction.

Is there any way to turn this feature off? I don't want it to close any session unless I close it.  I have searched the manual but see no way to stop this unwanted action.
Title: Re: DIR-615 Hard wire disconnects
Post by: FurryNutz on March 28, 2013, 07:30:21 AM
I presume that if there is no data flow in either direction, that any router might close the connection due to inactivity and would keep the connection open if there as some sporadic data flow with in the 5-10 minute time frame to reset this time out. Does your faux telnet program have any sort of "Keep Alive" connection option?
Title: Re: DIR-615 Hard wire disconnects
Post by: obliox9 on March 28, 2013, 09:37:28 AM
This is the first router I have had that does that. I did set an idle out timer on my mud client and that is how I can confirm it closes the session at 10 min.

I was wondering if session limits are in effect if I choose the Address Restricted option?

Title: Re: DIR-615 Hard wire disconnects
Post by: FurryNutz on March 28, 2013, 09:40:30 AM
Possible...i would test each of the settings out.

I would check the following as well:
Turn off ALL QoS (http://vonage.nmhoy.net/qos.html) or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
Ensure devices are set to auto obtain an IP address.
If IPv6 is an option on the router, select Local Connection Only or Disable IPv6 options under Setup/IPv6.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Disable IPv6 Multi-cast Streaming if IPv6 is not being used.
Turn off WISH, and WPS under Advanced.
WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
Set current Time Zone, Date and Time. Use an NTP server feature. Tools/Time.

Well Hello Again!

I want to report that it seems all the issues that I have reported in this thread have been solved, and you can mark this thread as RESOLVED.

The issue of the router locking up, dropping all internet connections, and requiring me to pull the power plug to reset it was solved (I believe) by upgrading to the latest FW v3.13NA. This was described in the release notes as "fixed the wireless disconnect issues."

The issue of the router loosing connections when I was using my MUD client or with telnet sessions when I am logged into an internet server but idle is a router issue as detailed in the manual I referenced above. I have solved the MUD client issue by setting up an idle trigger. The telnet session disconnect issues persists.

The issue of troubleshooting these problems at the same time my cable modem was misbehaving was challenging, to say the least. I must confess that I was losing faith in the DIR-615 and had purchases a still shrinkwrapped Linksys WRT54GS2 for $15 as a replacement, however it will now be a backup. The DIR-615 performs quite well.

The only issue remaining for me is the date issue, but to be frank, I don't really care if it keeps the right date or not. All it needs to do is toss packets the way I want. I have plenty of other devices to keep time.

I would like to thank FurryNutz for helping me. I appreciate your
professional approach and patience. I don't know if your paid support or just a volunteer, but you should be congratulated for the effort you put in here! Thank you.
