@dlockers So the TP-Link UE300 arrived today, I plugged it into my LG CX (I tried all the USB 2.0 ports) but no luck, I was only getting 30 - 50 mbps rather than 480mbps (I have a 500mbps connection). Anyway, I'm returning it to the seller, I think i got a faulty one or something or an incompatible one. That doesn't mean the idea doesn't work, it has and still does work for a lot of people, but its luck of the draw in terms of getting the right brand/adapter to work with your TV. The poster above recommended the Rankie gigabit adapter, you could also try the ugreen brand or the 'cable matters' brand and see how they perform for you.
