I have the DIR-655 Hardware version B1, Firmware version 2.00NA and everything has been working fine for about 3 months.  Lately the internet connection to all the computers would just stop.  All the computers are connected to the router and the router is connected to the cable modem and their is no indication of a problem.  The lights are all on and the router status shows the cable status as connected and the network status as established.  I can't open any webpages, or all the ping would time out.  It happens on all device, Windows Vista/7 PC, Mac computer, Linux laptop, and iPhone/iPad.  The problem gets fixed when I reset the router or just wait about 5-10 minutes and the problem goes away.  That normally isn't a problem, but it's starting to happen twice a day now and it is really really annoying when I'm playing games.  Anyone else have this problem or have a solution?  I tried the FAQ and searching the forums, but the FAQ didn't help and the I spent 3 hours searching the forum (Not sure what keyword to use, only have generic ones that yield too many results).

Ensure DNS IP addresses are being filled in under Setup/Internet/Manual?
Turn off QoS options.
Turn off Advanced DNS Services if you have this option.
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.
Set Firewall settings to Endpoint Independent for TCP and UDP.

What wireless modes are you using?
Try single mode G or mixed G and N?
What security mode are you using? WEP, WPA or WPA2? Preferred is WPA2 and Cipher type to AES only if your device support this.


Let us know how it goes.

Did you ever figure out what was wrong? I'm having the same exact issue.

I am also having the same exact problem.  My internet works fine when connected directly through the Cable Modem, but not through my DIR-655.

Make sure you power cycle the cable modem when switching back and forth from connected to the PC and connected to the router.

Anyone have any comments ? I have the same exact issue and cant figure out why im getting these connections timeouts while playing games etc. Ping just jumps through the roof for several seconds then comes back down to normal.
