My issue with this router AXE5400 Tri-Band it it awful.

This is my 3rd router everytime I upgrade the firmware I lost Ethernet capability.

It is showing live but when browser the internet I got no internet.

All the Ethernet port are live when plug in just couldn't access the internet but wi-fi work fine.

I afraid to upgrade to the latest firmware and don't want to return this router again.

Anyone has tips  or did anyone test their Ethernet port after firmware upgrade.
