I have the TP-Link Archer AX20 | AX1800 with 1 TP-Link RE605X AX1800 Wi-Fi 6 Dual Band Range Extender.. In my country, the AX1800 is out of stock and it has been like this for a long time. The TP-Link RE505X AX1500 is available and I'm wondering if it's ok to buy 1 or 2 of these and connect to my AX20 router and set it to OneMesh. This means that my AX20 router will have 1 AX1800 and 1-2 AX1500. Is it ok?
