MacBook Pro (late 2016) 5Ghz wifi network issue I have a two moths old the new 15” MacBook Pro and basically I”m happy with it. My main issue is with WiFi networks. I have an Airport router with two networks defined (with two different names): a 2.5 Ghz and a 5 Ghz. Each time after restart I’m getting connected to the 5 Ghz, however after couple of hours the MacBook switches to the 2.5 Ghz network, and the 5 Ghz network is NOT included in the list (I can’t select it). I’m almost sure it’s not a router definition issue, as at the same time, in the same location, all my other Apple devices: MacBook Air, Mac Pro, iPhones, iPads, Apple TVs have both networks as an option. I also didn't face this issue with my previous 4 years old MacBook Pro that has been replaced by this one 2 months ago. Until today all my attempts to solve this issue failed. My MacBook Pro is a 15-inch, Late 2016, 2.9 GHz Intel Core i7,16 GB 2133 MHz LPDDR3, Intel HD Graphics 530 1536 MB, Sierra 10.12.2 Any ideas?
