Wi Fi not working - greyed out switch and frustrated daughter using large amounts of 3G data allowance!
Straightforward repair as I had all the tools from a previous repair (my wife's 4S broken front screen).
I followed the 'reflow chip' repair from an iFixit member and removed more parts than necessary. I should have followed the Upper Antenna Replacement guide which would probably have been easier - once I realised where the wi-fi module was - it was a very easy swap & rebuild. Great part & service from iFixit as ever - Wi Fi working perfectly = happy daughter & lower data bills!!
