Do you have Mac filtering? Remember, the wireless Mac address is different from the ethernet address. Mac address filtering does pertain to ethernet connected computers. I had an Airport connected iMac that I wanted to connect via ethernet. The router had Mac filtering, but for the Airport Mac address. I could not get the iMac to connect to the internet until I turned off Mac filtering. If you have Mac filtering, try turning it off.
