I decided to go with ubuntu on my desktop that I mainly use to watch media on and also occasional other functions. I have a wireless card installed that is not immediately supported by Ubuntu, so I brought the whole machine into the other room to connect it directly to my router, and started trying different suggestions from online searches. After not getting very far I gave up for the night and went to bed. The next day I turned on the machine to try a different solution, and had no connection through eth0 I checked the settings and made sure that ethernet was still enabled in my systems bios. I gave up and just re-installed Ubuntu, and I still cannot get it to connect to my router. I tried again to install, making sure that the install was reformatting the drive. Would the setup keep the config files from a previous install? what should I be checking here?

Bizarrely removing the wireless card from the system fixed the issue and I'm now connected.

Hi, welcome to LQ!

Strange solution, but if it works for you, all the better. =o)

Only time I have ever seen that is when the card is in hibernation and wont wake up. Pulling the card or depriving the computer of power at the mains should also work.

The really strange part was that the ethernet port is integral to the motherboard, but pulling the pci wireless card fixed the issue. When it showed no connectivity to ethernet it still showed a no wireless symbol for the network connectivity icon at the top right. after removing the wireless card it then showed the normal two arrows and allowed connectivity to the router through an ethernet cable.

I still haven't gotten the wireless card working, there are linux drivers for it online, but i'm not at all familiar with compiling a tar and haven't been able to find a tutorial that really makes sense to me. I did try a tutorial for this card using ndiswrapper and using the windows drivers, but that resulted in not working. apparently the linux drivers that are available don't work, or don't work correctly or something according to most of what I've been able to dig up.
