After every power outage, my Obi202 connected via the Obi Wifi adapter never reconnects to my home network by itself and must be manually re-connected. I have to dial *27, connect to the Obi Setup network, and put in the information again. I'm using automatic DHCP. Any suggestions for an Obi newbie?
I suggest having your router always issue the same IP address to your OBi each time.
Having your OBi use a static IP address would seem to be best, but implementing that can be harder.
