This is acontuation of my previous post.

I decided to reset the device and start again from scratch.

After resetting I can't get it to work at all.

I purchased a Mesh device (RE330), the set up was easy but didn't work more than 30 feet from the router.

So back to the WPA4220.

It's now plugged into a socket about 10 feet from the router but I can't get it to connect by pressing the pair button and then pressing the pair button on a nearby TL-PA410 device.

Any help would be appreciated.
