I have a small single level ranch about 1200 sq ft. I currently have a Nighthawk router with a Wi-Fi extender. Overall, it is pretty good however I get some lag with streaming TV in my garage. I have a single car garage attached, which is furthest from the router. The extender is in the kitchen, but isn’t that effective. In addition, my outdoor Wi-Fi cameras are not consistently connected likely due to decrease signal. Would I be better off with a stronger router or should I go with a mesh system? Any advice is appreciated. Thank you.
