Previously I had Archer C20 - AC750 which had 2 extender TL-WA850RE & RE450(EU). Both Extender was able to extend 2GHZ network of my Archer C20, and RE450 was also able to extend my 5GZ network of Archer C20.
Recently 2 Weeks before I have bought AX10(US) Wifi 6 router, and replaced it with my Archer C20.
When I reconfigure my 5GZ Extended setting on RE450, it is not able to detect it, all settings of 5GZ is set to auto, and I tried with MU-MIMO activated and deactivated, also I tried all version of Mode on main router, but none got detected on extender.
Kindly help me what settings should I choose so that my extender is able to detect my AX10 5GZ.
