Comment 29 for bug 572777

I'm one of the people with an Intel chip (5100) in a Lenovo x200s. I'm sorry to say that compiling and installing wpa_supplicant 6.10 did not fix the problem. (But thank you also Nils.) I am basically unable to connect to WPA networks. I can usually connect to WEP, but the connection is slow and almost unusable. Following Nils I installed wicd and killed network-manager and nm-applet. That didn't help either. The wicd connection attempts fail with a "bad password" error.

This strikes me as a pretty serious issue.
