Unable to access router through LAN port in BPI R2-Pro

Recently I have build image for BPI-R2 Pro from source code given by BPI-SINOVOIP which is mentioned on webpage of the BPI-R2 Pro but I am unable to access my router from LAN port after flashing that image on router even I have tried by changing multiple IP it is not accessible.

Why this problem occurs ? is there any other way to access my router.

I encountered the same problem. I found that when using kernel version ≥ 6.1, the LAN port speed is extremely slow or even inaccessible. It is normal when using kernel version 6.0 and below

Could you publish somewhere working image with fixed LAN speed issue? I tried to use OpenWRT images published by mj22226 (mj22226 · GitHub), but the images have LAN speed issue.
