I have a 2016 Samsung series 8 4k SUHD TV. I recently switched over to Verizon 5G Home Internet. The tv has connected and worked ok for a week, disconnecting at times. But today TV won’t connect. All other devices (Romulo TV, IPad, iPhone) are connected.

The TV’s IP address now shows as 169.254…. I have rebooted the Verizon gateway and have turned the TV.on/off and also unplugged both. 
what am I missing?
