Hi,

I have a 3-floor setup with 10 users, all connected via WiFi. Here's my current configuration:


Current Setup:

  • 10G fiber → BE450 (3F, main router) → 1Gbps LAN port → AX80V (4F, satellite) → wireless backhaul → AX3000 (5F, satellite)
  • All devices running EasyMesh with same SSID
  • BE450 using 10G port as WAN for internet


The Problem: I'm told that to use ethernet backhaul between BE450 and AX80V, I must connect their LAN ports (not WAN). This limits the backhaul to 1Gbps, creating a bottleneck for 4F and 5F users.


My Question: Since BE450 has both 10G WAN/LAN and 2.5G WAN/LAN ports, and I'm using the 10G port for internet (WAN), can I configure the 2.5G port to work as LAN for ethernet backhaul to AX80V's 2.5G WAN port?
Some say 2.5G port cann NOT be used as LAN in Mesh mode, but some say it CAN be used.


Desired Configuration:

- Internet: 10G fiber connected to BE450's 10G WAN port 
- Backhaul: BE450's 2.5G LAN port → (ethernet cable) → AX80V's 2.5G WAN port 
- Result: 2.5Gbps ethernet backhaul for EasyMesh

Additional Info:

  • BE450 specs say "2.5G WAN/LAN" (not WAN-only)
  • AX80V has a 2.5G WAN/LAN port

Is this configuration possible with current firmware? If not, are there any workarounds or planned updates?

Thanks!

In general, under normal circumstances you should connect the main router LAN port to the satellite router WAN port.

This way you would have all four LAN ports on the satellite router free for connecting wired clients.

You already have that working: BE450 (3F, main router) → 1Gbps LAN port → AX80V (4F, satellite)

The easiest way to test this scenario is to move the ethernet cable as you intend to:

BE450's 2.5G LAN port → (ethernet cable) → AX80V's 2.5G WAN port and test if this connection is working as expected.

If this doeasn't work in your case, you can always revert back the ethernet cable to the previous ports.

Thanks! By the way, in my case, since most users connect via WiFi, I don't need to keep LAN ports free on the satellite router. However, I was advised that connecting to the satellite's WAN port would cause issues with the EasyMesh network, so I'm currently using LAN-to-LAN connection (BE450 LAN → AX80V LAN).

Is there any known issue with using the satellite's WAN port for ethernet backhaul in EasyMesh? Or does WAN-to-LAN connection work fine for mesh networking?

I'll test the 2.5G connection and report back!

There was a rule when setting up the ethernet backhaul, that initially you use LAN to LAN connection and when everything's confirmed OK, switch to LAN to WAN connection.

Sometimes there was a case when the etehrnet backhaul doesn't work properly on LAN to WAN and switching to LAN to LAN fixes that.

All you have to do is to move your cable to LAN=>WAN connection and test the ethernet backhaul stability and if it doesn't work that way to revert back the cable.
