LG C2 intermittently disconnects from Wi-Fi

And I can't reconnect or even turn on/off wifi without hard reset (pulling plug).

Owned TV for 2-3 weeks and now this has happened 4 times. I've checked my wi-fi and all other devices are connected and have internet.

Any thoughts? Should I just return it?

I've been super pleased with the OS, picture quality, etc otherwise.
