I finally got mine to work again using the AX11000. It started off doing just like yours and I saw no progress until I set the 86U as a wireless node and saw the big blue bar go across the top for about a minute. After that, I found and set the device as a node.
Next I changed back to the AXE 11000 and set it up again using the ethernet back channel, and it worked again with that.
It is almost like something is stuck in the Bios and won't turn loose. I do notice some confusion when you are searching for a node, a popup window shows up saying cancel or apply while the system is still searching for a node. There may be confusion as to what action to take when that happens.
Also, if you have two node devices, the number of nodes should show 2, not 3. The Router is set as a Router/AiMesh device and is not counted in that number. Remember, my attachment is from an AXE11000 so it may look a little different.
I was wondering, if you were to change the configuration to back to a normal router or one of the others, if you would not then be able to set it up again as an AiMesh node..
You might need to do the same thing to the other 92u and bring them back one at a time..
finally, i had for over 2 months a great AIMESH network with amazing coverage and speeds with 1 Aimesh router AX11000 and 2 AX92U via ethernet backhaul.
i was on my asus router companion and saw that i had 3 offline nodes that DID NOT exist along with one of my AX92!. i removed one and then i couldn't remove the other ones. once i removed then one of my AX92u was gone
I could find it on the ADD aimesh nodes but no matter what i did via LAN or WAN it coulnd't be added back. i tried hard reset but the results were the same
i need help. i have over 100 IP related devices and i will lose so much time if i have to factory reset my router and start from the beggining.
