have now a second device were after a TC70 GA2  update the WIFI is disabled and refuses to be enabled.

first device is a Symbol Branded EV1 GA1 unit which was updated to GA2  K12-01  release.
it was running release MV 092214  build with correct ROWETSI wlan ID and Wifi was working before the update.

the second one is a MVT GA1 TC70 whihc was first working ok on GA2 K12-01 release  but now after update to GA2 K13-01  is failing in the same manner.

what can we check

also the downgrade to GA1 releases is somehow not possible as there is some kind of protection on GA2 images.

see some messages  in log files..
