Comment 24 for bug 1005832

Just a note on one possible source of these kind of problems.

The upstream 3.4-rc1 kernel included a commit (7e79a39 iwlwifi: use valid TX/RX antenna from hw_params) that caused problems with the tx power in iwlwifi and could lead to these "authentication to xx:xx:xx:xx:xx:xx timed out" types of messages. This is fixed by "a5fdde2 iwlwifi: fix TX power antenna access" in 3.5-rc3 and in the 3.4.4 stable kernel. This wouldn't affect precise but could be a cause of problems when running quantal.

This problem should be fixed for quantal in 3.5.0-1.1, so if you're testing the quantal kernel be sure you're testing that version or later.
