So... I checked when I got home this evening. I still have an RT-AX68U, but all of my RT-AX58U have been put to use elsewhere for friends, family, ... The RT-AX68U is a "lesser" device than the RT-AX58U since it does not support 5 GHz/160 MHz wifi. I WPS reset the RT-AX68U, and I installed the "latest" Asus firmware, v3.0.0.4.388_24646, dated 2024/02/26 — yes,
@Tech9, it's from February of this year, and the device has hit EOL designation, but... I added the RT-AX68U as an AiMesh node to my GT-BE98 Pro using 1 Gbps wired backhaul. I was able to add my two IoT VLANs — one 2.4 GHz and one 5 GHz — to the RT-AX68U, and devices connected using the proper VLANs, Ip address ranges, and isolation. The screenshot shows the connected devices:
I rebooted the RT-AX68U with the WAN cable disconnected, and the AiMesh node connected using 5 GHz backhaul. The two devices in the screenshot above (
temporarily bound to the RT-AX68U) reconnected the same way as with wired backhaul.
I'm convinced the RT-AX58U would do the same, but even better!
