After upgrade from 2.9.42 to 3.0 beta 10 we have problems with wireless on MDA/PDA devices. Device connect normally but after some time (eg. 1 minute) data don't pass across interface, but it's still connected. If I disconnect and reconnect again, some time everything is ok and then the same problem.
Tested on two RouterBoards with MDA Vario and HTC TyTn and problem is same... One RB run hotspot, one only simple DHCP...
After downgrade to 2.9.44 everything is fine...
Some suggestions ?
