My DLINK DWA-140 works fine. There was one in members market this morning for 8 quid but I think it sold.
I am in the US.![]()
Google seems to imply there are at least 165 US retailers selling the DWA-140, so I'm not sure that's a problem.
If you're interested in a PCI card instead then I can confirm the Edimax EW-7727IN works in 10.04.
For both of those adapters just make sure that if you're using WPA you set the version to specify WPA or WPA2, not WPA+WPA2. It took me ages to realise that was causing my connectivity problems rather than some inherent Ubuntu incompatibility.
Hmmm, I have it on WPA+WPA2 now, maybe I should change it & see if the freezes stop. I can't there are no options with just WPA or WPA2.
Maybe try turning of encryption completely for a while, but I doubt that's the problem. If you can connect to the wireless then I don't think using the mixed encryption setting is an issue. When my router was set to that neither of my adapters would connect at all. An older 3Com was fine though.
