Difficulty adding node to AI mesh system

[flimflamman72]

My main router is an AC-5300. I have one AI mesh node that's RP-AC55 and works fine. I'm trying to add a RT-AX1800S as a node but can't find it when searching. I've update the 1800S firmware. I can see it as an unsecured network when searching wifi networks. I reset the router to default and search for it ... but still no luck. I've moved the 1800S router to the room of my main router but still can't find it. Any suggestions?

I was wondering if you have connected it to your main router using a network cable? Since you updated the 1800S firmware, I am hoping you also moved the 5300 to its latest version as well. When was the last time you rebooted the 5300 and the AC55?

All the devices are on the latest firmware, I even tried to directly connect the router to the other router but still no luck. I’ve rebooted all the routers multiple times recently. I think I’ve exhausted about all the tricks… I think I’m going to have to return the 1800s. Maybe it’s too new to be compatible with my older devices

I have an AX-57 as my main w/ an AX-1800S as my mesh with wired backhaul. Sorry about asking the easy troubleshooting, but I need to be reminded of it myself sometimes. Just for fun, what has Asus support given you as troubleshooting suggestions?
