Make and model router?
Who has full admin rights to the router?
Also run and post the results of "ipconfig /all" via the Command Prompt.
Ok so I have gotten it to work by setting the speed manually to 10mbps full duplex which as it seems its the exact problem I have had with my motherboard ethernet card. I cant see the router model and make since its attached to the ceiling and my isp has admin acess to it.
results from ipconfig:
