Has anyone else got one of these and if so have you noticed an issue where your devices stay connected via wireless but just stop working for a few minutes here and there. The internet connection never drops, and the talktalk router stats just show a huge amount of errors on the 5Ghz band. It's happening a lot to my wife's iphone 6 and my 6+. Just got off the phone with Talktalk technical support and they have "boosted my wireless signal" apparently, although I'm highly doubtful they did anything, how could I check?
