[Commotion-discuss] Connectivity issues

I get that chan.c warning message from time to time with UBNT Nanostation M
radios (and I think also sporadically on TL-MR3020) using the ath9k driver.

This warning doesn't appear to affect connectivity for me, and it seems to
occur most commonly when I issue "wifi restart" command.  There is mention
of similar warnings from the mac80211 driver stack on various threads on
OpenWRT-devel listserv, so this might just be an ongoing issue with OpenWRT.

Also, I have so far only verified Commotion's multi-SSID setup works on
ath9k, ath5k, and ath9k_htc drivers (with the latter only supporting *2
SSIDs*, i.e. adhoc + 1 AP).  What hardware are you using?
