I haven't figured out any kind of pattern yet, but it has happened quite a few times over the last couple days. Basically, I'll be browsing the internet or using the FaceBook App and I'll notice that I don't have WiFi bars and it just says LTE or 4G. WiFi will reconnect fairly quickly all on its own. I'm at home and in the same room as my 5th gen Airport Extreme router, which has never given me any issues, so I'm going to assume that isn't the problem. Is anyone else is experiencing random WiFi disconnects? *edit* I'm sure it is entirely possible that I'm having issues due to the 5s being 64 bit, but I'm not sure how that'd be related to WiFi. Additionally, I only have F.lux installed.
