Yesterday I noticed Wifi wasn't working on my iPhone 5. Couldn't play a radio station with TuneIn or run a speed test. Toggling Wifi didn't work. Switching between my 2.4GHz and 5GHz Wifi networks didn't work. Nothing fixed the problem. I powered the phone off and back on. Everything worked suddenly. Has anyone else had this happen? I kinda hope I'm not the only one, which would suggest it's a software issue that will be fixed.
