Wifi Broken After Root
I successfully rooted my Kindle Fire HD using the tools found in this thread, then successfully installed Google services and the Play Store. Worked fine for about an hour, then I noticed I no longer had a WIFI connection. I went to Settings and saw that WIFI was turned OFF and that it could not be turned back on. Shut down for a couple of hours to let the WIFI radio cool off, but had no luck when I turned the Kindle back on.
So I did a factory reset on the device. Now I have no WIFI and can't even set up the device with my profile since there's no internet access.
