Here is the situation I need assistance with: I have ATT Unverse and they provided the Modem/router. The WiFi connection from router provided is not dependable nor will it reach my pool area. The router keeps dropping and it is disconnecting my external cameras when it does. I was thinking that I could connect a new router to the Modem/router they provided but I am not sure what to get. My house is about 4000 square feet and I want the wifi signal to reach my pool area. Would it be better to get the top of the line router, would that help with the signal dropping? Would I need an extender with it? Should I get a mesh system? Should I just get an extender for my current Modem/router that is provided by ATT?
