Recently, I have bought deco e4 (3 packs) and set up them by following the instruction in the app. But after just 1 day, the node in my bedroom had a confusing issue. Sometimes i can use youtube but i can not use browsers and sometimes i can use browsers but youtube stops working although the internet is working normally. Though this issue will disappear after 30 mins or 1 hour but it affects my experience a lot. Can you help me solve it?
