Linksys - Connecting Pc To HUB, Says No Network Access

I recently moved downstairs in my household and was overjoyed to finally be able to use the network hub downstairs. Ive been using wireless lately which has served me well for my pc, but not for my Xbox 360.

Anyway I decided to plug in the ethernet cable and see if I might be able to set it up on my pc and then save the settings to a USB stick so I could use it for my 360 (right now it wont connect, says it cannot get an IP adress).

I didn't set up the network (my father did) so at this point I cant fiddle with the settings. Everything should be working, but its not.

When I plugged my pc directly into the hub upstairs it worked perfectly, but for some strange reason down here the connection comes up as

Unidentified Network, No Internet Access

Has anyone else had this problem before? The hub should be working (i even plugged it in after taking the cables out, resetting it if you will, no dice).

Also, forgot to add, it says that there is no connectivity, but I checked the connection and it automatically gets the ip and subnet address, which works fine with the wireless.
