Try G with WPA2 and TPIK only as well.

Do you have any friends, or family you can take this router to and test temporarily by chance? Just curious to see if this problem follows.

Do ALL devices loose connection? Test one device at a time? Turn OFF ALL devices except for one and test, then graduate turning on the rest.

Mode G, WPA2, AES failed.  Unfortunately, my wireless printer does not like TPIK, so that's a no go.

Eventually, all the devices lose their connection.  I've seen where just one Android phone being connected to the router will lose its connection.  I'm unsure if just the printer connected to the router will lose its connection.  Have you tested an Android phone, mode N with this router?

For now, I'm going back to the safe and working firmware Rev 1.01, Mode G, WPA2, AES.  Thank you for the suggestion of trying a different location though.

Finally, another thing I found wrong with Rev 1.02 beta was that the router did not assign IPv6 addresses anymore.  Rev 1.01 works fine though.

Ok, I'll forward this onto D-Link support.

Please do a factory reset, then send the v1.01 FW file, then factory reset once more then setup from scratch. Please use IE or FF for doing this process.

I too, have the same exact problem as above. I do hope that a fix is soon in-bound. Would be a shame to have a wireless n router that can't be used with wireless n enabled.

I have been resetting it and trying different settings for months, as well. I actually have two of them. Both doing the same exact thing.

Link>Welcome!

What Hardware version is your router? Look at sticker under router.
Link>What Firmware version is currently loaded? Found on routers web page under status.
What region are you located?

What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.
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. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server 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.
 
Links>Wireless Installation Considerations and Managing Signal Congestion
Ensure the default (dlink) SSID name is changed. Can be anything and not something thats already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
What wireless modes are you using?
2.4Ghz Routers only: Try single mode G or N or mixed G and N?

Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Try setting a manual channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
Try turning off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.
Enable WMM Enable Under Advanced/Advanced Wireless.

[JoeKhar]

I've done all of the above. Plus some. Nothing but Samsung phones. I also have a surface pro that has the same symptoms when using nothing but N.

If this would help D-link support, or whoever looks at the firmware. The Surface pro uses a Marvell AVASTAR 350N Wireless network adapter.

One at a time, or all at once. They all lose connection at once when using nothing but wireless N and AES. Gigabit lan is still working properly. I've been troubleshooting it for about 2 months straight. I am at the limit at what I can do. I had to resort to G for my devices not to lose connection.

I actually have two of these routers. Trying each one by itself, both have the same exact result. Both are H/W Version: A1



I used a dir-655 before this. Only reason I replaced it was because one of the gigabit ports went out. Oddly enough, all my devices now (With exception to the surface pro, which I didn't have a couple months ago) were working beautifully with it.

Hope this helps.

Any status on this?

My Job is pretty busy sometimes. I haven't checked the forums in a bit. My apologizes.

[FurryNutz]

Understand about being busy.

Do wired connections go down as well or just wireless?

Be aware that Samsung and D-Link are tracking some issues with Samsung products:
http://forums.dlink.com/index.php?topic=54171.0

I presume this is one possible problem, however since you are seeing problems with a different HW client, this could be a mix of problems with the router and client devices.

I have forwarded this on to D-Link and they are aware of it. I would recommend that you phone contact D-Link support, ask for level 3 or higher support and see if you can get any information on this and see if any fixes maybe on the way and get some immediate help and information.

We've provided all that we can here in the forums and this needs to be addressed by D-Link.
I would recommend if you can get some time, find a local store that has a good refund policy and check out a different DIR series router as a test to see if a different model works. I would presume the DIR-655 would work however I'm not confident in its operation since you stated there is problem with it and it's on the list of effected products that Samsung seems to have issues with. Maybe try a DIR-636L, DIR-615, DIR-826L out and see if any one of these exhibits the same thing.
 
Let us know if you find out anything.

[JoeKhar]

The only issue with it was one bad gigabit port. It worked fine otherwise, I just used it as an excuse to get some newer hardware.

Two Galaxy S 3's and one Note 2. I had a sneaking suspicion that Samsung may have something to do with it. However, I did test my surface pro with my old Dir-655, then I have an old bekin N600 router that I haven't used in awhile, that worked without any interruption.

Only issues with that is, it's a basic fast Ethernet connection on the belkin.  I have always used D-link in one form or another. I would like to continue doing so. I thank you for forwarding it up.

The routers in my area have been the same since I have had my Dir-655 active. I tested every single channel.

Edit:
It was just wireless connections that went down. Regular internet continues to work. I didn't see that in the other post, sorry.

[FurryNutz]

How many other WiFi routers are near by?

Only channels to use that are preferred are 1, 6 and 11. Most of the others are side band channels that the routers and devices use as a secondary connection between them.

If you lower the power output of the 657 from High to Medium or Low, same thing happens?

[JoeKhar]

Yes, high, medium and low. All the same thing. I do use only 1/6/11. Indeed.

There are no other N routers nearby. All are G. They are on all channels between 1-6-11. 3-5 etc

Busted out an old blackberry tablet just now. It disconnects also. I'm about to try an old Dell mini 10. Every device I'm thrown at it so to speak has done the same thing.

[FurryNutz]

Hmmm..having those other wifi routers near by could also be causing problems. I would hoping the lowering the power might help. Darn it.

Ok, can you try this?
Set single mode N, then try single mode G then B.
Set a manual channel thats not being used if possible, pick one. Try 4 or 8 maybe?
Set the Band Width to 20Mhz Only.
Turn OFF WiFi security as a test, can turn it on later.

Do any of the device still disconnect after trying these modes with the suggested settings?

I'm attempting to see if any of these setting help or not.

[JoeKhar]

Dell mini 10 worked.. but I forgot it was only wireless g, not n. Seeing if I have an old wireless n usb card laying around.

[FurryNutz]

keep us posted...
might be narrowing it down to the N mode...test G modes with all devices if you can...Then try N later.
