RT-AX88U to RT-AC88U AiMesh - No 5GHz WiFi

[ReignOfComputer]

Hi, I have an RT-AX88U AiMesh Router with an RT-AC88U connected as a Node. They are connected by Ethernet.

From the Web GUI, the RT-AC88U has:
Connection Priority: Ethernet
Connection type: Wired

Only the 2.4GHz LED is lighted on the RT-AC88U. The 5GHz LED is not lighted up.

2.4GHz devices connect fine to the AiMesh node, but all 5GHz devices connect to the RT-AX88U.

My working theory is that because the RT-AX88U broadcasts WiFi 6, the RT-AC88U isn't compatible and just doesn't broadcast at all. Any ideas would be appreciated, thanks!

Does the AC88U WiFi work normally when used as a standalone router? If not, then consider re-installing the firmware, resetting to factory defaults, configuring from scratch, and trying it again as just a router. If no 5 GHz signal, then maybe the hardware has failed.

Seems to work fine as a standalone router, but I've always had a weird issue where not every device could connect to it on 5Ghz (e.g. the iPhone would connect, but the laptop wouldn't).
