I've shut it down, restarted, changed net name, and even did the 0.0.0.0 etc. Annoying to shut phone upon each disconnect. Sometimes it works, more often, not.
Foxfi Bluetooth fails to connect to my Razr. Razr's BT fails to pair. Prior to ICS I was able to BT a 4g connection to IPAD3!!!
That was great. NOw, my Smartphone is now a Dumbphone:-)
