Please try this patch: From: Luis R. Rodriguez <lrodriguez@xxxxxxxxxxx> Subject: [PATCH] mac80211: do not trigger beacon work if scanning We were issues probe requests to the associated AP on the wrong band. This leads to finding not bitrate. We should not be doing this, so prevent the timer from stuffing beacon loss work on the mac80211 workqueue. Signed-off-by: Luis R.
