Thank you, I didn't see that there was a second image. The link button is on the basic remote. The image of the remote you posted is not a basic remote. This is what the basic remote looks like: https://www.amazon.com/XRT132-Remote-Control-Vizio-M50-D1/dp/B01LFUGYE4

With the remote you posted, seems like you'll just want to go into the TV menu and change the network settings to get it reconnected to the network.
