I just got this set and whilst I can get it to work, pushing the WPS button on my router doesn't copy over the settings.

Hi,

To clone the router's Wi-Fi settings to the TL-WPA4220 you first push the WPS button on your router and then (within 2 minutes) push the "Wi-Fi" button of the TL-WPA4220 for about 1 - 2 seconds.

I've tried to go into the device settings and change the SSID manually to my current Router/Wifi settings but the problem is when I do that, it creates 2 networks with the same name.

 

How do I get it to just extend the current one please?

If you mean that you see two Wi-Fi networks with the same SSID when using a Wi-Fi Scanner/Analyzer software, then yes, this is normal.

Every Wi-Fi AP broadcasts its own network. Whether the network names (SSIDs) are the same or different makes no difference.
