Known issues:

Motorola Droid 1, 2 and 3 – Works reliably if wifi module is configured for ADHOC network or module is ‘connected’ to an existing access point. Yes, Droid 1,2,3 DO support adhoc networking! Something in the WiFi module used is flaky when connected to the tiwlan drivers used on these phones. I have been working with the manufacturer to resolve this. Other Android phones using the tiwlan chip/driver may be affected.
