Let's play a little game I like to call "One of these things is not like the other" Windows 7 Laptop: iPhone 6S Plus: iPad Air 2: 2015 15" rMBP: Were you able to figure out which one is not like the others? You did, congratulations! You win, but the answer is so obvious Stevie Wonder would be able to win this game. All 4 devices were near each other and all about the same distance from the WiFi hotspot, about 5 feet. Turning off WiFi and turning it back on in Sierra seems to resolve the issue temporarily, but soon, it's back to being crap again. And I've found articles online that suggest deleting a few files would fix it, but I've tried that, and it hasn't. I never had this problem before upgrading. Anyone else out there had a similar issue and found a working solution?
