[BPI-R3 Mini] LAN Port Disconnects Everything

Hello All,

I have a BPI-R3 Mini that came preinstalled with OpenWrt. After setting it up, it seems the LAN port is having issues with using a network. Currently while trying to find a fix, I’m connected a Raspberry Pi 5 and an HDHomeRun to a switch, to the BPI. They will connect and then after using the network from the RPI5 (usually for less than a minute), it will become unreachable via SSH or Ping (as well as the HDHomeRun, the other hard connected device).

I’ve looked at various logs and nothing seems to indicate that anything happens, nothing says it disconnected or throws an error, it just looses the connection to the BPI. I’m happy to post any logs to see if anyone else can find an error, but right now I’m at a loss.

You may want to upgrade to the official OpenWrt

Could you check ARP beaviour of your Banana PI. Discovered some weird ARP behaviour on mine (provide ARP replies where this shoudn’t happen) tha could cause (depending circumstance) that devices become impossible to connect to.

Check with tcpdump -i eth0 arp -ne
