I'm a new user to Linux in general and I feel like I'm in over my head. I decided to put Ubuntu 12.04 on this old system after it got hit with a really nasty virus. However, when the installation finished, it cannot connect to the wireless network at all. To be more specific, It can't even see the wifi period. It normally saw the wifi through a USB adapter. I've tried to do some troubleshooting but most of the instructions still feel foreign to me.
If someone could help me run through what to do, I would really appreciate it.
