@luke3 The Archer C9 is "End of life" so doubt TP link would be doing any further enhancements to its firmware, Further more the hardware would not be compatible with WPA3 I would think.

@rafaelsdev I use the AX20 (AX1800) with a RE300 extender with no problems, I get my full WiFi speed when connected to the extender.

@Solla-topee Can't see that firmware is available to download yet and extender is not prompting any update? How long till the new firmware appears on the TP link website? Thank you.

@Nkol7 great stuff 👍

Ah no, sorry about that!

@Nkol7 I see on the Deco app when setting up Deco's if there is an issue with Bluetooth perhaps, if you connect to the Deco's wifi and then try setup like that, it might help? So turn off Bluetooth...
