There is one room in my house that the wifi signle is very weak. I now need it to be strong because it's the kids play room and my son has playstation 4 and it will not connect. Does Comcast offer some type of solution for this? I extenders will just slow down the games while he is playing them.
There are other options. Google for WiFi repeaters / range extenders, WiFi mesh systems, powerline ethernet adapters, MoCA adapters. Good luck !
