Comment # 12 on bug 1187761 from Ivan Ivanov

Ok, so right now it looks like Wi-Fi chip itself is ok, 
but you don't have 'connection', right?

I am not a 'wicked' expert, but the following configuration
looks suspicious.

How did you come up with this?

To me WIRELESS_MODE looks incorrect. If you want to connect to
WI-Fi Access Point it should be 'managed', which is the default.
