I have just purchased a tp-link wi-fi 6 Range Extender and can't get this to link to my new Telstra modem.

The Tether app is detecting the extender and my modem. I enter bpth passwords for 2.4ghz and 5ghz but it fails to connect.

I've even tried to push thew wps button on my modem and the extender but still doesn't connect to the internet. Does anyone have any ideas to try?
