It's funny how people are so eager to generalize from "my wireless card didn't work on Gutsy out of the box" to "Ubuntu [has] very broken wireless driver support".
My generalization stems from the number of comments with peers and countless internet searches for fixes.
In the case of peers, wireless card support was a common complaint.
In the case of searching, looking around the forums will give you a pretty good idea that wireless card support is pretty bad. I bought a standard Belkin wireless card from the local Staples. It should have worked, but didn't.
