<div dir="ltr">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.<br><br>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.<br>
<br>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 <i>2 SSIDs</i>, i.e. adhoc + 1 AP). What hardware are you using?<br>

The 'WARNING' message comes from the wireless driver.<br>
