Got it today mining at 100M, having some problem with Wi-Fi option and failover seems to be the only option with multiple pools. More to assess though.
Which pools are you trying to use?
Wifi is very buggy right now, but should work with most b/g WPA2 networks.
Currently wifi will NOT work on open networks (i.e. needs a password), and you'll have mixed results if your router is in mixed mode etc
