Upgraded Wi-Fi from spectrum last month had to reset router almost everyday as it lost connection got new modem and router from them now PS5 lags to the point where I can barley play anything or even watch YouTube had guy come check everything said who ever did it last time left the old wires there causing interference issues but he took them out put new connectors in said everything was good played for bout an hour and back to the lag bs
What could it be and how do I fix it?
