I have a DIR-655 that was working for the longest time, then out of the blue it just decided to stop getting a connection to the internet.  I can connect to the router, but for some reason, it will not get any network settings.  When I check the status/device info/WAN section, it just shows:
IP Address :     0.0.0.0
Subnet Mask :     0.0.0.0
Default Gateway :     0.0.0.0
Primary DNS Server :     0.0.0.0
Secondary DNS Server :     0.0.0.0
Advanced DNS :     Enabled
I have tried disabling the Advanced DNS setting, but still no luck with getting network settings.  I've tried messing around with the firewall settings, but no luck with that either.  
When I do an ipconfig /all, all of the DHCP Enabled are set to "no".  I have tried a release/renew without any luck.  Running out of ideas here.  Any help would be appreciated!  
EDIT:  Should probably mention that I have tried changing the router IP address and updated the firmware to 2.0.7NA
