My laptop (Dell Latitude PP01L ) was running Ubuntu 10.10 32 just fine (installed from CD worked right away) but it's cd drive was getting flaky.
After making a mistake I decided I just wanted to reinstall so I installed Ubuntu 10.10 over the network ethernet boot. After finishing everything works except networking. Ethernet port is dead and wireless cannot see anything.
However when I was able to boot from CD these devices worked just fine. Any idea what is causing this? I tried installing over network boot a new install of 10.10 and then Ubuntu 10.4 and exact same thing.
