One of the Ethernet ports are disabled/turned off/bad, or you need a crossover cable. Many computer Ethernet ports don't automatically switch.

Save the packaging in case this goes nowhere. It's a $2 cable but most stores put it in a blister-pack and charge 5-10x that much.

You could also find/borrow another known-good Ethernet device and make sure both systems are at least seeing it. Don't restart each time you plug in the cable. Just plug it in and look for a link. If either end shows a link light or "plugged in" status then both are talking at the lowest level. If both seem okay to another device but not to each other then assume you need the crossover.

Edit: I forgot. You still need to determine what ip address your system acquires when connected. (ipconfig above) If airimba WAPs are handing out 192.168.0 addresses then it'll conflict with ICS.
