Aimesh node (RT-AX86U) is being dropped when RT-AX89X is the primary node

[faisal1969]

In my AiMesh setup, RT-AX86U's 2.5Gbps port is connected to 10G SFP+ port of my primary router RT-AX89X via CAT6 (in order to create MultiGIG Ethernet backhaul).

The setup has been working fine until I recently upgraded the firmware for all the nodes. After the firmware upgrade, RT-AX86U has been dropping frequently from the AiMesh network until I perform a reboot. RT-AX86U firmware version is 3.0.0.4.388_22068 and RT-AX89X's firmware version is 3.0.0.4.386_47468. Sometimes the backhaul speed of RT-AX86U reduces from 2.5Gbps to 10/100Mbps. I also have a pair of ZenWIFI AX nodes who are connected to RT-AX89X's 10G Base-T port via 2.5G switch. There are no issues with those ZenWIFI AX nodes. All nodes in my setup are using Ethernet backhaul.

Any idea/suggestion to resolve it? Should I downgrade the firmware of RT-AX86U?

Thanks in advance.

RT-AX86U firmware version is 3.0.0.4.388_22068

This firmware caused AiMesh issues on many different model routers. Test the new build or revert to what works for you.

Thank you, I have just updated the firmware you suggested. Let's see if this fixes my issue.

So far so good, it has been 12 hours when I downgraded the firmware of RT-AX86U. Everything seems to be running ok.
