This issue is reproducible even without NM, using wpasupplicant directly to create a adhoc network, and is definitely true on iwlwifi and rt2800pci; so it deserves to be looked at at the kernel level.
FWIW, I though I had seen it work properly on ath9k, I'll test again tomorrow to be certain. In any case, I'm strongly considering blocking the creation of WPA/WPA2 personal networks in NM as a stop-gap measure to avoid people creating insecure ad-hoc networks until that's really fixed in the drivers. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- 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
