Hello, 

I just bought a TP-Link range extender (RE450) which should be OneMesh compatible, but i can't seem to connect it to the OneMesh of the Archer AX20 router. 

As far as I can tell, when I connect the range extender for the 1st time to the wireless network, i should see OneMesh in the SSID name, but i don't see it. 

I've tried from the Tether app from the phone, and from the PC which was connected via ethernet cable to the range extender. 

The OneMesh option is enabled in the Router configuration menu. 

Note that the range extender is working properly, and it extends my wi-fi coverage, it's just that my devices do not switch automatically from router coverage to range extender coverage, and this is the only purpose i bought this range extender. 

According to this both the router and the range extender are onemesh compatible, so i don't understand why it's not working.
