[BPI-R64] WAN port not working

For some reason the WAN port on my BPI-R64 doesn’t work, though the LAN ports do.When I plug in a LAN cable the LEDs do not light up and I do not see any messages from the kernel.

I’ve tried several different images (Ubuntu, OpenWRT) and none of them work.

Do I have bad hardware, or am I missing something?

This is what the linux kernel sees (WAN & LAN1 are plugged in):

maybe you need to set wan up

ip link set wan up

I’ve tried that, both running in OpenWRT recovery environment, and in the normal environment.

I do see that WAN is being set up in dmesg:

[   10.706954] 8021q: adding VLAN 0 to HW filter on device wan

I then see messages for the LAN ports:

[  128.169883] mt7530 mdio-bus:00 lan4: Link is Up - 1Gbps/Full - flow control rx/tx
[  128.177409] br-lan: port 4(lan4) entered blocking state
[  128.182628] br-lan: port 4(lan4) entered forwarding state

But nothing for WAN.

right, i do not see wan-port in dmesg too…so try it manually first with the command i’ve posted. if that works we have a config issue…

Setting via ip link does not work.

No LEDs on WAN port, which leads me to believe it’s a kernel or hardware issue.

sad…then indeed it looks like a HW issue…can you check soldering-points/circuits of wan-port?

It was a bad solder joint on the ethernet transformer.

8 pins were not making contact, after resoldering it the WAN port now works :smiley:

Thanks!
