I couldn't find my old post so here's the skinny. I installed 12.04 yesterday because 12.10 was causing problems. The installation went smoothly. After rebooting, there was no mouse control and the network wasn't recognizing my computer (wired connection). I was having difficulty pasting outputs and such due to no internet. However, I just booted the flash drive with 12.04 on it and selected "Try Ubuntu W/O Installing." I now have full control and internet. Can anyone help me figure this out?
