Topic: 11.04 Connection Issues - Wireless Works / Ethernet Won't (Read 1619 times)

Thank you for the assistance! I figured it out about 30 minutes ago and thought I would post an update. I was talking to a friend of mine on the phone and it just sort of hit me. I turned the onboard lan, amongst other things off in the bios of both machines to save power. I restarted both machines, changed the bios, plugged in the ethernet cable, and it automatically connected (which for now kind of resolves my issues with not being able to see the network manager). I mentioned before that it might be really simple, but I couldn't figure it out. DOT, but at least they're running again and without connectivity issues.

There is no network card listed in your lspci output, because its (internally?) connected to the USB hub apparently.
Can you post the output of

I've been mining from my neighbors wireless network (with permission). I'd run roughly 2x40 feet of usb extension cables to antennas outside. My signal strength is pretty good, but I was having stability issues and minor disconnects turned into huge issues as some changes with Catalyst 11.6 removed part of my GUI menus. One of which contains the Network Manager. Any disconnect would prompt me to simply click reconnect, but if I wasn't home... The machines would run full tilt, but not hash a damn thing. DOT!

Today, I had my local internet provided come out and run a new internet line for my house. The line works great on my Windows machine, but neither of my 11.04 machines will work. I have the line coming out of the wall into an arris router --> dlink wireless router with 4x ethernet plugs on the back. When I connect the ethernet cable to my windows machine the light on the dlink comes on, but not when I connect to either linux machines. I've done a lot of reading and done some testing, but the output still kind of confuses me. These commands are with my wireless network plugged in as I was using the machine to browse for issues as well.
