I'm using a 7620n router(openwrt BB14.07 r43276) with a secondary SSID
enabled, after running for sometime I found these trace information in
system log. I remember there is already a ticket
https://dev.openwrt.org/ticket/17032 , I wonder if these two problems was
caused by a same reason?
Here is the error log:
