I have a very strange thing happening. I can connect through my dir-685 wirelessly from ONE (of 6) computers in the house. I CANNOT connect via lan from any of the computers plugged in that way, and shareport says there is a network error. Have rebooted everything several times.
Looks like this...
computer 1:
Plugged into lan port 1. Router screen sees and acknowledges connection. No internet access, cannot access router by typing 192.168.0.1
Computer 2:
wi-fi dlink (works with regular OR guest wi-fi access) can access internet and BUT NOT router (by typing 192.168.0.1)

Computers 3 and 4:
cannot access internet OR router.

Note: it was all working for all computers two days ago, yesterday noticed no connectivity, I initially figured internet was 'down' but with troubleshooting discovered modem works fine. I am on here writing to you via wi-fi through router, so it *is* sort-of working!!! No other computers (besides this one) work. They all say no IP adress is being assigned when I try to 'repair' connection at computer.

IDEAS???
