MT1300 WAN port not connecting

Technical Support for Routers
1

The WAN port on my MT1300 is not showing a link when I connect to a Meraki MS2010-48LP or the Ethernet port of a TDS Telecom fiber NID. I verified that the WAN port does work by connecting my laptop to it. I discovered that if use a Netgear GS308P to connect the MT1300 and the fiber NID, that works. This is not ideal, but at least I've got it working. Output of "logread -e link" shows "Interface 'wan' has link connectivity loss". Looks like the MT1300 has some sort of hardware handshake issue with my two devices. Are there any configuration changes I can make?

Firmware v4.3.19
Architecture: MediaTek MT7621 ver:1 eco:3
OpenWrt 22.03.4 r20123-38ccc47687
Kernel Version: 5.10.176

Try these commands in the SSH:

#Check the WAN interface name
ifconfig
#If the WAN is eth1 (Subject to actual conditions), and fixed to 100Mbps
​ethtool -s eth1 speed 100 duplex full

The WAN link is connected at 1Gbps when I have it in the Netgear switch. The WAN interface device is "wan" so I set it using:

ethtool -s wan speed 1000 duplex full

I verified this still works when in the Netgear switch. I then connected the WAN port directly to the fiber Internet and it doesn't link up. The ifconfig shows:

How about the to fix 100 for the interface 'wan'?

And please export the syslog and PM me if the wan of MT1300 does not work with the fiber device.
