OK, Please take out the wireless, that (at this point) would only confuse our search for the problem.
Delete the network connection(s) you currently have. Point is to force W7 to identify a new connection. Reboot, boot up with the lan cable connected (for the first time).
Please check that, when you connect the lan cable, the green light stays on and the orange starts to flicker.
Make a note of all the LAN related things W7 asks or shows you upon booting.
