Ethernet to HDMI instead of wifi?

Purchased a Visio TV recently. Sporadically I have had issues with connecting to my wifi, usually when I first turn on the TV. I hit the power button, the TV hangs during boot up, and then I get a message indicating that it couldn’t connect to the internet. If I power down and power back up again it almost always connects immediately, and everything is normal from there. I think I’ve only had one instance where I lost connection mid viewing, or had to re-power up more than once.

The TV doesn’t have an ethernet port. Just HDMI and USB. My router doesn’t have HDMI or USB, just ethernet. I’ve seen ethernet to HDMI adapters. Before I go out and buy one, has anyone successfully used one of these adapters to convert ethernet to HDMI on their Vizio TV for internet connection?
