Did anyone manage to solve this issue yet?
I have two GT-AXE11000 devices with a 2.5gbps ethernet backhaul, and like everyone in this thread 6e connection is only established from the router but not the aimesh node.
I’m having the same issue with new ZenWiFi ET8 nodes. 2 identical nodes connected via Ethernet backhaul and I can only get WiFi 6/6E from the router and not the node. Has anyone resolved this yet?
I don't have ET8s, but from experience with my AXE16000 and AXE11000 AiMesh, if 6 GHz/6E works with one it will work with the other. Try to place the device next to the node (if possible) on the far side from the router, then bind the device to the node. Upon my testing with the device right next to the node it will connect to the node.
I think I made some progress last night. Still need to do a bit more testing when the family isn't here and I am not in work meetings, but it's looking promising. I turned OFF "Ethernet Backhaul Mode" in my AiMesh System Settings (so I can add another node later that is WiFi backhaul only) then I set my ET8 to "2.5G WAN first" under "Management" of that node. All of this was done before without success, but I found something new this time. Go to "Wireless" in the left menu and then scroll down to the 6Ghz section. I am in "Smart Connect" mode but I think this will work if you aren't. I found that there is a drop down box for "AiMesh Wireless Backhaul". This WAS set to "Use as dedicated wireless backhaul" so I changed it to "Use as both backhaul and fronthaul connection." After making which change I was able to see the 6Ghz radio on my node.
I'll update later after I get a chance to do some more testing to see if there are better ways to do this.
