I use 2 methods: ping my webserver run ifconfig to check for existence of apclio and local IP address from result of both I could tell if I needed to call wifimanager to restart. Since b17* it's been stable enough to reconnect itself so I no longer use this and I cache data until I am able to connect again using urllib2.

Thanks for your replies. Let me describe a little better what I'm trying to do. I built a simple data logger, that I want to be smart enough to turn only attempt to transfer data to my server when it's "home". If I'm out driving in my car with it, I don't want it to be trying constantly to get to it's server. Heck, I could even turn wifi off at that point and conserve battery. Does this make sense?

Me too, would also like to know. Be great to be able to use the Omega as a WiFi strength mapper (maybe add in GPS and a second module also with GPS to implement a poor man's DGPS?)
