I’ve been getting a few emails from people who have had their Android 4.0+ devices get stuck at -200 dBm while the network shows as connected.   It appears to be a bug in Android, since Wifi Fixer is just showing the relative signal that Android WifiManager reports.

If you have this error, please turn on logging in the app for a while, then send me the log. I am attempting to collect as much information on this as possible to file a bug report with Google.

I have an experimental workaround in testing.
