This router wifi signal is very weak, and the wifi speed will degrade once in a while, the only way to fix it is to restart. Fedup with this and upgraded to Asus RT-AC68U, even web browsing is so much smoother and responsive ( FYI, my house all using wifi, total got about 12 devices but not all using at the same time ), even streaming 4k movie through wifi is not a problem right now with the Asus router
