I’m experiencing an issue with Ethernet. Initially, Ethernet works correctly—I can successfully ping 192.168.1.1 from a PC connected to the board. However, after some time, it stops working. Even though the LEDs on the Ethernet port are still active, there’s no response to ping requests. I’m confident this is not a hardware issue, but rather a software-related problem.
Here is the relevant output from dmesg:
