Hi, I got some weird issues with our router and I came to conclusion it might be faulty but not really sure about it so I decided to write here and listen to advices from here. We've received our new Hub 3.0 router on 15. January 2017 so its basically new. Our old hub is being used as access point upstairs ( I turned off dhcp and set 192.168.0.2 ) Both stayed operating dual band and everything was fine until 21. February. Around 8-9 PM I started to have slowdowns on both 2.4 (skype using laptop) and 5 GHz (game on playstation) then I was disconnected completely from internet but I stayed connected to wifi. Then connection came up down up down several times when I lost my patience after hour and reboot our router. Laptop on 2.4 Ghz connected with slowdowns but worked. But 5 Ghz wasn't working at all on any device I tried. I mean I could connect to wifi but it wont allow me to access internet. I could load webpage like once in 5 minutes. After few hours of changing channels and testing everything we got in our house also reseting both routers and setting them up again I came to solution that I had to turn it off (5Ghz) because otherwise I got issues with connection on some devices even on 2.4 and also connecting to internet via our old hub 2.0 which is upstairs and shouldnt have anything to do with it. Its really weird and I never witnessed something like this but on other hand on cable everything is perfect. Is it possible router overheat itself? Just to mention there are 6 phones, 2 chromecasts, playstation, two laptops and one stationary PC so its rather important to have good wifi around. Sorry for long post I couldn't explain it differently. What do you think about it?
