Any Ethernet wireless adapter capable of being configured as a client or bridge will work. This will simply connect to the Ethernet port on the TV and connect to your wireless network.

Plenty of options in the ~$40 - $50 ish mark from various brands incl TP-Link. If you want 5GHz support for better performance you'll pay a little more. 

Thats what I thought, so I connected the old TPLink via ethernet but TV doesn't recognise it, still asking for a USB device.

You're obviously doing something wrong, no idea what. 

If the wireless bridge is confiured correctly connected to your wireless network and plugged into Ethernet the TV will get an IP address automatically. I don't know why you'd be in a menu that says anything about USB devices.

If you plug your laptop into the Ethernet port on the bridge and disable WiFi in your laptop do you get an IP address and have internet access? If not the bridge isn't configured correctly.

Simplest fix for older Sony TVs if you want to use them as a DLNA renderer over wireless is a Blu-ray player, bonus being if the player is pretty recent like a BDP-S6500/6700 they are compatible with a lot more formats, both via DLNA and and for USB playback. Just a thought. Works well here with a 8yo NX720 panel. 

Ok it pains me to say it, but what I have is a TP Link range extender, not a TP Link network adapter, so I need to buy a network adapter I guess.  

Hey Radiotron, not sure how the blu-ray fits in, what I have been doing is plugging in my MacBook to watch Netflix on the Sony TV screen but the quality is poor.  So I was hoping that if get a network adapter then I can bypass the need for the laptop and watch Netflix on-line using the TV.  

I posted a recommend for using a BDP because app support for that generation of TV is pretty much dead. Assumed you'd be using TV for DLNA render, not built in apps, such as they were, and you had a dead UWA-BR100 you sought a replacement for.

Pardon me, never mind. If it had working Netflix app still, I'd be a bit surprised - that model generation was on sale before Netflix...

You want a device that can act as a wireless client, i.e., station infrastructure mode. For example, a Ubiquiti Nanostation Loco M2 or M5. Legacy so can obtain cheaply.

Hey Radiotron, thanks I needed to know that, perhaps it's not worth paying the $50 or so bucks to get a network adapter just to find out that the TV won't stream Netflix anyway.  I don't know what DLNA render means but I'm assuming you mean using it as a screen, I can play DVDs on the Xbox.

What does Legacy mean?  I took a look online and the Ubiquiti Nanostation Loco M2 or M5 cost more than the TV is worth. https://www.nzgameshop.com/network-wireless-access-points/ubiquiti-unifi-nanostation-m5-mimo-wireless-bridge-base-station 

Legacy means end of line, i.e., not manufactured. Also you aren't looking at the Loco version which is cheaper. Better off buying a new TV.
