Samsung Smart TV suddenly stopped connecting to internet

I have been using my Samsung Smart TV for a couple of years with no problem. However, yesterday it decided that it could no longer connect to the internet. It tells me that the "network is not connected" and I need to set up a "wireless network using an internal LAN adapter". When I start the process my router name shows up and I can click on it. The tv shows that it is checking the connection and then has the message that it is "connected to the wireless network but not the router". The following settings are found automatically by the tv:

MAC Address: 5c:a3:9d:02:d5:43
IP Address: 192.168.1.72
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.254
Server: 192.168.1.254

I did an ipconfig and PING test for the tv and the router and these are the results:
