Ohh man. Get this: normally when I'm home, I get my two routers and one neighbor's. But then all of a sudden, my Icon couldn't find one of mine: saw the other one, the one neighbor's.......... AND THE ENTIRE NEIGHBORHOOD'S, including the various cable company WiFi hotspots. Just one reboot after turning off WiFi and it's been normal ever since.
But seriously, this WiFi thing is going to be nuts. My wife recently upgraded to the Icon herself, so we both now have smartphones and only 4GB to share. As for me, I was upgraded to an Icon by accident due to my second 822 bricking with the 'Bootable Option' error. Let's just hope Nokia's firmware updates fixes this issue someday...
And yes, this is coming after a phone reset after installing 8.1-u1.
