Thanks to an ArchLinux forum thread, I discovered that the issue is with multiple drivers trying to manage the Broadcom chip. I'm using the restricted "wl" driver, but the opensource drivers load too.
To fix this, I added the following three lines to the bottom of /etc/modprobe.d/blacklist.conf - blacklist bcma blacklist brcmsmac blacklist brcmutil I'm not familiar with how the restricted drivers are distributed in Ubuntu - it seems that the long-term fix is to blacklist the opensource drivers when the restricted one is enabled. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/863799 Title: Connect/Reliability problems when I create a WiFi Ad-Hoc network on Oneiric To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/863799/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
