U330 Ethernet not working, wireless works fine

I have an Ideapad U330 that will not get online using ethernet in windows. Before you ask, no it isnt my router. When I use an Ubuntu bootable disk, the ethernet works fine and I can surf the web without issue. I reformatted and installed windows 7 x86 (It had windows XP previously and the ethernet didnt work there either), installed all the drivers, and updated the BIOS, the ethernet still does not work while the wireless works fine. I thought this was a hardware issue until the ethernet worked with no issue in Ubuntu.

No go, still the same issue. I can connect to network computers over it, transfer files, just no internet. It seems it's not resolving the DNS server (and no, it's NOT a problem with my network).

Re: U330 Ethernet not working, wireless works fine

Alright well I booted it up in Ubuntu again to get the details, got an IP of 192.168.1.142 and DNS of 192.168.1.1. When connecting through Windows, I get an IP of 192.168.1.198 and DNS of 192.168.1.1. The only difference that it pulled up that was different from Windows' ipconfig /all is that it pulled a slightly different IP.

 

But, lo and behold, manually putting in the IP pulled from Ubuntu worked. But each time I try to go back to automatic IP in Windows it keeps delegating it to 192.168.1.198. Is there any reason why it keeps doing this? I would imagine that the router could have a setting having that out of an accepted range, but since that's the only IP it'll obtain otherwise, I'm wondering why that is.

 

I guess all there is left to ask is whether there's a way to keep the IP and DNS as automatic settings rather than manual. This is a college campus and I'd like to make sure that it wouldn't interfere with other computers or locations, including off-campus locations. Any thoughts?
