The beta is going well.  About to plug in the final new feature: non-managed networks.

This will let you designate a network for Wifi Fixer to turn itself off while you are connected to it, for networks where Wifi Fixer’s connection checks don’t work. 

(It’s possible you might be on a network where icmp echo/ping to the AP isn’t allowed, and there’s no route to the internet for the HEAD check.)
