Me and my freind both have our desktops at our school. I have a WiFi card, and he does not, so we've run a cable from my ethernet to his ethernet port and then i set up shared internet on my computer.
I'm running windows 8, he's using windows 7, and it used to work right up untill he patched his windows 7. Also, last weekend, I went home and he stayed so we put my WiFi card in his computer, and set up his computer to share network with me. From this point, the system stopped working.
Those are the only other changes to our setup. We've both tried running sfc /scannow commands, where some files where fixed. We have also checked with different laptops to see weather one of our ethernet ports may have broken which does not seem like the case.
Anyone have any suggestions on what we can do?

If you typed any DNS servers into your IPv4 properties window you should remove that entry and just let the router handle the DNS instead. I believe that may be the reason you are showing two of the same default gateways for your DNS server, there should just be one gateway showing up there. You should make sure you have two functional DNS servers typed into your routers settings for DNS servers.
Hope can help you.
