I bought this product half a year ago. After I bought it, I put these three decos in place and the situation was not so bad. But now the network is unstable from time to time, causing my game to lag.

Deco mesh doesn't make wifi better and my computer can't connect to it

My computer can't connect to the deco mesh, but all other devices in my home can connect. My computer can connect to the original wifi but can't connect to the deco mesh network
