i got my A3 Wifi some months ago and now finally found the time to set it up.
for some strange reason, my device has no wifi-antenna nor a SMA connector for one but since i can connect to it from my computer, i assume wifi works fine.
however, the device does not connect to my access point (WPA2, 26 characters pass). coming across your post here, i feel this might be the solution. i will try tomorrow (now is 21:00 and the A3 makes horribly loud beeps every time it fails connecting or restarting).
will let the forum know how it looks tomorrow
