We've been able to reproduce it on multiple drivers: iwlwifi, rt2800pci, ath9k and iwl4965. I think we can safely say it's reproducible on most drivers, and thus probably something that needs to be fixed in kernel code outside of drivers' code.
Philipp; you may still want to run 'apport-collect 905748' to add extra information to the bug report which will make things easier to debug; as was suggested by Brad. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/905748 Title: Create WPA2 adhoc is Open, not encrypted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/905748/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
