GL-MT 3000 - LAN Port not working

Technical Support for Routers
1

Hello!
I use the router GL-MT3000, Firmware 4.5.16. I do have an issue with the LAN Port ETH1 which is not function.

The WAN port ETH0 is assigned an uplink to the WAN router and a WAN IP address 192.168.2. 209.

However, I haven’t been able to connect to a notebook via LAN cable for some time now. The interface on the notebook does not get a connection. The connection remains “off”. Of course I tested this with another PC or different cable without success, the interface stays “off”.
Even the router did not recognise the connection to the notebook, the interface stays off.

I’ve already reset the router to factory settings. Even without success.
I ask for your help.

Your Jo

Hello,
I have done an other check.

I connected the LAN ETH1 Interface of the Router with a small, unmanaged Desktop Switch Netgear GS105. The concerning Switchport stays down, the LEDs are off. Using an different LAN cable as above.

Crosscheck with the LAN Port of the Notebook, the Switch Port is going up, the LEDs are on. Using the same LAN cable. Even Windows recognized the LAN Port is up.

Yours Jo

any update with the above issue? Because im having the same issue. Lan port eth1 would not connect to anything. Just want to note I have reset everything back to factory default to make sure is not firewall or NAT forwarding released.

Check log it say the following.
mtk_soc_eth 15100000.ethernet.eth1: Link is UP - 1Gbps/Full - flow control rx/tx
br-lan: port1(eth1) entered blocking state
br-lan: port1(eth1) entered forwarding state
update: eth1(UP)->apclix0(UP), active path3:

Hi,
May I know if the question has resolved now?
Please contact support@gl-inet.com to let us provide the customer service for you if you still have.

Hi,

Could you please share more detail syslog with us, including the LAN from disconnect to connect the Ethernet cable. As according to your mentioned logs, seems the LAN/Eth1 port hardware is ok, please check if can the lower device DHCP process, such as discover/offer/request/ACK?

This look suspicious to me :thinking:, this is the psysical port lan we speak off not some sort of usb ethernet adapter?

normally you won't expect a ethernet port to be half duplex, when i think about half duplex my thoughts are pointing to wireless.

I would like to see the following configurations /etc/config/network and /etc/config/wireless and /etc/config/firewall would be nice to see if something isn't right here.

And if possible also show logs :+1:

^ also it is possible your ethernet cable is not good, on my mt6000 it reports under port: twisted pair, not MII, maybe it is a cross cable?
