I’ve had this older Samsung TV that never had problems with WiFi connections to my router, which is 10 feet away from it. I recently replaced the router with an Archer AX11000, which of course has 2.4GHz and 5 GHz access points, but now the TV fails to connect to either of them. “Wireless network connection failed”. I have the latest TV firmware installed. Anyone have an ideas of what could be done to get this TV to connect to my router via WiFi? I tried many of the suggestions that I found on websites about this topic, but still have no success.
