MT3000 Beryl AX 4.7 beta LAN port speed

Seeing some posts about negotiated port speeds I tested using the LAN interface.

The 100Mb/s link negotiation took numerous cycles where the PC reported that there was no cable connected. It eventually fell back to 10 Mb/s and connected.

Hi,

  1. Please replace a new one network cable.
  2. Please plug and unplug the network cable several times.
  3. What PC port highest speed is? 1000Mbps or 2.5Gbps port?

The cable was a new, out-of-the packet, CAT 7 STP cable.

Which also worked fine with the Opal.

I did think to do that. And I tried another new CAT 7 STP cable as well.

This was between the 2.5 Gbps Beryl port and a 1 Gbps PC port.

Given the way the link came up I took it to be a link negotiation issue.

Is there a way to fix the speed/duplex on the Beryl?

This should have read:

This was between the 1 Gbps Beryl LAN port and a 1 Gbps PC port.

You are running a Beta firmware so there will be unforeseen issues. You need to test the router with Stable firmware, latest firmware is 4.6.9.

Try a Cat5e cable, they tend to have less issues, or a Cat6 patch cable. But start with Stable firmware. Make sure you perform proper reset of the router through Luci.

You can also try these commands.

Try executing the commands in the SSH:

Check the WAN interface name:
ipconfig
If the WAN ifname is eth1, and fix 1000Mbps:
ethtool -s eth1 speed 1000 duplex full autoneg off

With the router running 4.6.6-op24 it connects without issue at 1 Gbps.
