I’ve now upgraded three of my four machines to (k)Ubuntu 8.04. My print server / desktop upgraded flawlessly. My daughter’s laptop, however, had one issue.
We have been using a Linksys WPC54G wireless card in this machine. Upon reboot, the wireless did not work. Plugging into the wired network didn’t seem to work as I tried different cables. After I pulled the wire from another laptop and plugged it in, the wired connection worked as it should.
I found help on the Ubuntu Forums. All I needed to do was
sudo apt-get install b43-fwcutter
which obtained the firmware for the card from the web. This turned out to not be a major issue, but I would have hated to be where I couldn’t get to a wired connection.
