madwifi multiple mode issue

[simonnewton]

Binary package hint: madwifi-tools

MadWifi driver states compatibility with multiple mode interfaces (VAP's). Only one station interface may exist on the wifi0 device, but multiple AP's may exist, or AP and Station together (source: http://madwifi.org/wiki/UserDocs/MultipleInterfaces).

I'm sorry that nobody has cared about your bug yet. Are you still affected by this bug? Thank you for telling us!

[simonnewton (simon-simonnewton)]

Wow thats a blast from the past. That hardware was retired years ago, so im unsure if the bug remains.

[Thomas Hotz (thotz-deactivatedaccount)]

Then I'll close this bug.
