Sending this from the Ultimate Edition 1.8 Live DVD.

The newer 1.9, although also based upon Ubuntu 8.04, wouldn't connect
wirelessly. Perhaps the 1.8 version will solve your problem?http://ultimateedition.info/Ultimate_Edition_1.8/I'm not sure if we can count on Linux Mint 5 KDE getting out of Beta
soon. They still have Mint 4 in beta stage for XFCE and Fluxbox.

Also, this Ultimat Edition 1.8 is holding a wireless connection that
wasn't consistent in the Linux Mint 5 KDE Beta 045.
