Hi - I was hoping someone could help with my ethernet backhaul.

Current setup: 

Main router: Archer BE230 V1. 

Firmware: 1.1.1 Build 20240912 rel.12553(5553)

Satellite router: Archer AX55 Pro. 

Firmware: 1.3.1 Build 20240426 rel.31941

I recently upgraded my main router to a BE230 and daisy chained it to an AX55 Pro V1 that I updated the firmware to support ethernet backhaul (1.3.1 Build 20240426 rel.31941). I successfully added it as a mesh satellite router and saw the icon change from wifi to an ethernet cable but ONLY when I used the 1Gb port, not the 2.5gb port of the AX 55 Pro. 

I've troubleshooted this for hours now, trying to unmesh the device and use it as a standalone router and when I do that, I can access the 2.5gb port when connected directly to the BE230 2.5gb port (it has 2 - a WAN and LAN). The BE230 also show's it's connected to a 2.5gb LAN on the satellite so I know it's not the port on the 55 that's broken.

But when I change the setup back to Mesh with the 55 Pro as the satellite, the 2.5gb port isn't detected and the AX55 keeps trying to connect via wifi instead. When I swap the ethernet cable to the 1gb port, it finally detects ethernet again and changes the icon. 

Does anyone have any suggestions? Any advice is appreciated!!

Other things I've tried: 

1. Swapped the ethernet cable, which didn't work. And doesn't make sense, because when I unmesh the satellite router, I can use the 2.5gb port without an issue.

2. I've thought about switching the AX55 as the main and using the BE230 as the satellite, but that's not preferred since the BE is newer with wifi 7.
