(sleep mode) so much so I end up having to turn unit off and on for it to find it again, as it just says Configuring IP Address, or words to that effect, it only began doing this yesterday (with the other arnova tablet I had which went back due to screen problems today) we have several other things running 100% fine on wifi, without drops in connection, so why has my tablet suddenly started dropping connection in standby mode when all was fine until yesterday?

TIA
