Comment (by anonymous):
Same issue here on an Archer C5 v1.20 (build r44918 with DFS enabled like
explained here:
http://wiki.openwrt.org/doc/uci/wireless#dfsradar_detection) when setting
channel to "auto" or to a channel requiring DFS.
After a while, it seems the wlan interface can't execute a scan operation
(error with {{{iw phy0 scan}}}).
After a while too (couldn't see if these 2 facts are related), the channel
is changed to "36" forcefully with:
{{{
daemon.info hostapd: wlan0: IEEE 802.11 driver had channel switch:
freq=5180, ht=1, offset=1, width=3, cf1=5210, cf2=0
}}}
When using a channel not requiring DFS, the log in the ticket is not
visible.
