Comment 55 for bug 291271

Well, it seems you're right. HP is extending the warranty and replacing faulty wireless components in quite a few laptop models. (Not mine, though,.. at least not yet.) Here's the link -- http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=ca&docname=c01087277#c01087277_identify

It seems this is a hardware failure related to overheating. They have a new bios to run the fan more to try to prevent the failure if yours is still working. (I actually installed a bios update last year that runs the fan continuously, but it doesn't seem to have protected mine.)
