(wired) Network card configures only once then not again
 
Hello mighty linux warriors,
I have an unusual problem that I need some help with. (Long Post, sorry)

I have a small Lenovo ideacentre Q150 "netbook" computer that I have configured dual boot. It comes with Windows 7 Home Premium and I have installed Fedora 17. This is a low powered machine with everything, including the NIC, integrated directly on the motherboard.

I know the card works because I did a net install to install Fedora. First I installed everything and I found Gnome 3 doesn't work well with this graphics card so I switched to XFCE4. The first login must have worked because I logged in and installed software for XFCE (and other stuff). Eventually I decided I must have corrupted something by installing and uninstalling software so I decided to start over. I discovered the installer disk was no longer able to bring up the network card. I fooled around with it for awhile and eventually decided to start over from scratch and used gparted to delete the linux partition. After that the installer disk was once again able to bring up the network card. I was again able to login and bring up the card but only the first time. Once again the installer disk is no longer able to bring up the card.

My best guess is that the driver is leaving a node (or something) on the disk and subsequent attempts are failing to create a new one. I am hoping somebody can tell me what node to delete (as a short term fix) and what to do to prevent this problem from happening again.



Thanks for any assistance.
