AX6000 (RE900XD) WiFi 6 Mesh Range extender will not tether
Received new AX5400 (VX420-G2h) hybrid WiFi 6 Modem Router from iiNet and trying to connect AX6000 (RE900XD) WiFi 6 Mesh Range extender to the router via the TP-Link Tether App without much success. Within 'My Devices' on the Tether App the AX5400 (VX420-G2h) router appears as an 'unknown' device.
1. The Power LED status on the RE900XD extender is solid on (Blue).
2. Within the TP-link tether App, 'Tether' wants to Join Wi-Fi Network "TP-Link_Extender". This is despite the phone Wi-Fi already connected to "TP-Link_Extender" network. I selected the "I'm connected" within the "Connect to your network" stage. The App searches for the extender but fails to find it.
Having searched online, couldn't find much helpful information about tethering capabilities of the AX5400 (VX420-G2h) hybrid WiFi 6 Modem Router to the AX6000 (RE900XD) extender.
Has anyone had similar issue with same devices and found a working resolution?
