I have a Netgear WNR834Bv2 router. My ethernet cable runs from my modem to my router, my laptops connect wirelessly, and I have one ethernet cable running to a desktop (Dell Optiplex) next to the router. The other day, I lost the wired connection to the desktop. I'm still able to connect just fine wirelessly on my laptops, but I cannot get the wired connection to work. The connection works just fine if I run the ethernet cable directly from the modem to the desktop.
I tried doing a hard reset on the Netgear with no success; tried releasing/renewing IP addresses; tried using a different router that I have (a Linksys WRT54GX) and had the same problem (direct connection from the modem works but connecting through a LAN port on the Linksys results in the limited or no connectivity message).
If anyone has any thoughts I would really appreciate it!
