Any way to check if Bridge,Wifi broke on my Yun?

I'm pretty sure I supplied too much power to my YUN and broke my bridge/wifi part of the board. I supplied > 5V on accident.
I can run Serial/Digital/Analog commands, but when I try any sketch with Bridge.begin(). The sketch doesn't continue past this point.

I also can't connect to the YUN via my web browser via arduino.local/

Has anyone encountered this before? Any way to diagnose if my wifi hardware was fried?

Thanks!

Load YunSerialTerminal sketch to 32U4 through USB, open serial monitor, press Yun Reset.

If you don't see boot up then you killed it, could be you fried the AR9331 but it is possible you just got the voltage regulator, http://www.richtek.com/product_detail.jsp?s=282. Replacing surface mount components is beyond most people's soldering skills.

Bummer. Yeah, it's only reading back the serial when I print "~1" into the prompt.
When I press the yun reset, nothing happens.

I'm slightly interested in how to replace the part itself. Is there documentation on how to replace it?

Documentation is don't apply more than 5v. You can search for smd soldering replacement on Google but these are very advanced skills for a hobbiest.

Pretty much like buying a Rolls Royce if you need to ask what it costs, don't bother.
