>Does this issue still occur for anyone using Edgy?

>Basically, what cards don't quite work with wpasupplicant yet?

Yes, this still happens in Edgy. If I understood it correctly, it is a driver-related issue. On my particular case, I am using the open source acx driver shipped in ubuntu and I am affected by this bug. I can connect to a WEP network using iwconfig & co., but I cannot connect with network-manager (although n-m can scan networs and show their ESSIDs).

According to their webpage wpasupplicant has not yet been tested with this driver:
