 Hello,

 im using two TP-Link WDR3600 with identical configuration as dump AP's.
 Both have configured two VLAN seperated WIFi's on 2,4 GHz & 5 GHz each.

 Now i updated to the latest trunk version r45695 after running an earlier
 trunk for weeks. I noticed that my 5 Ghz WiFi's are now not coming up
 again on BOTH devices. Config seems fine, nothing has changed.

 Luci shows the WiFi's changes mode between unknown and master on start and
 end up as mode client, but are configured as Access Point.

 Here is my System-Log: http://pastebin.com/k26qi7fV
 There is a "Interface initialization failed" Error for wlan1 (5 GHz)

 /etc/config/wireless : http://pastebin.com/81WbrNVW

 iwinfo shows:


 {{{

 I dont see the Problem here. I managed to get it working again once by
 messing with the Interface Modes Monitor, Client and back to Master,
 enabling, disabling them but after a reboot, they dont come up again.
