I have a Fujitsu Stylistic ST5112 Tablet PC that was working fine in Gutsy. I upgraded to Hardy the other day when the Release Candidate came out, and now the wireless doesn't work!

After I upgraded, Hardy found my Atheros wifi card and hardware abstraction layer drivers. Before then, in Gutsy, I'm not sure which drivers I was using actually... but I guess not the Atheros ones. Anyway, now I can see the wireless networks with my cards, but I can no longer connect to them. When I try, the icon just spins around for 30 seconds or so and then gives up. I've tried disabling the new Atheros restricted drivers but all that does is make me unable to do anything with wireless.

Does anyone know what might be going wrong, or how I might fix it?
