MAC address not seen
I'm trying to connect a Samsung TV to a wifi network. The TV sees the 2.4GHz network SSID. Entering the password in network setup does NOT establish a connection.
At the router there are 10 systems connected to the network. In Advanced, Network, DHCP Server there are 10 MAC addresses shown. None of those is the MAC address displayed by the TV. The TV can connect via hard wire but this is only useful to determine if the TV can establish a network connection. (25' cable snaked via door way to next room.)
The TV is a 5 year old model UN40MU6300FXZA.
Standing at the TV my iPhone 8 speed test shows 84 Mbps download speed. At the router speed is 100 Mbps.
Is there any hope for a wifi connection?
