We have a Netgear Nighthawk R7900 router and 1GB internet speed. The PS4 only works on 2.5GHz WiFi in our house, and the maximum download speed is 23.1Mbps and the upload speed is 1.1Mbps. I installed a Netgear Nighthawk X6S Wi-Fi Extender in the back of my house next to my PS4 and saw a definite improvement. The extension cable can access the 5GHz signal, and then we connected the Ethernet cable to the PS4. Then the speed increased to 76.0 Mbps download and 3.3 Mbps download, which is three times faster! Setup was easy and worked flawlessly with our Netgear router. The devices recognized it without any problems and they didn't have to re-enter the password or anything like that, it just works.
