No internet connection on PC start

Every time I start the PC, GL-X3000 takes about 5 minutes to establish the connection. I tried both port (both are LAN) with the same problem with identical error.

I tried switching ports, changing cables, downgrading to 4.4.13 then to 4.4.9 with no luck. My old 5G router connects to the internet immediately.

Thanks

Hi

It appears there is an issue with Ethernet port speed negotiation.

Please try SSHing into the router and run the following command to set the LAN port speed to 1Gbps and see if that resolves the issue.

ethtool -s eth1 speed 1000 duplex full autoneg off

If the port is running stable, it can be saved permanently:

sed -i '/exit 0/i\ethtool -s eth1 speed 1000 duplex full' /etc/rc.local

Thanks for the replay

Sadly didn’t work, tried the method described above, still same error and long wait till the internet establishes.

Thank you for the update.

To help us investigate this further, could you please upgrade the X3000 to the latest beta version 4.8.2 and then provide us with the following information:

  1. Full Log File: Please export the complete log file and send it to us via private message.

    image1430×911 87 KB

  2. Network Card Model: Please also let us know the specific model of your PC's network card.

Additionally, as a troubleshooting step, we suggest you manually set your PC's Ethernet port to a fixed speed of 1 Gbps Full Duplex.
This can help us determine if the issue is related to the automatic speed negotiation of your PC.

Here are the steps to do this on Windows:

  1. Open the Device Manager (Windows + R, then type devmgmt.msc).
  2. Expand the Network adapters section and right-click on your Ethernet adapter.
  3. Go to Properties, then click on the Advanced tab.
  4. Select Speed & Duplex from the list of properties.
  5. Change the value to 1.0 Gbps Full Duplex.
  6. Click OK and restart your computer to apply the changes.

Please let us know if this adjustment makes any difference.

Thank you for the reply

  • X3000 updated to 4.8.2 beta.
  • Network card: Intel 2.5 Gb Ethernet, Internet Ethernet Controller i225-V, speed is set to 1 Gbps Full Duplex.

Now the X3000 behaves differently, connects after about 3 minutes then disconnects for about 3 minutes before establishing a stable connection.

Based on the current logs you've provided, we suspect the issue may be with the Ethernet cable itself.
Even when the speed is manually fixed, we can see that the connection repeatedly cycles through different speeds before it stabilizes.

Have you had a chance to test the connection using the Ethernet cable that came with the X3000, or perhaps a new, known-good Cat5e cable, or even SF/FTP cable?

Thanks,

Just tested 3 different cables, the included cable and two different SFTP cat 6a cables with the same problem. All these cables worked with the old 5G router with no issues.

We tested with an identical Intel I225-V network adapter but could not reproduce the reported issue. This suggests the problem may not be caused by the router.

Test environment details:

  • OS: Windows 11 24H2 (build 26100.6584)
  • Network adapter: Intel(R) Ethernet Controller (3) I225-V
  • Driver version: Intel, 2024/2/15, 1.1.4.43

Next steps you can try:

  1. Update your adapter driver to the latest available from Intel:
    Intel Driver Downloads
  2. Disable certain advanced adapter features, as suggested in Intel’s community forum:
    Intel Community Post
  3. Be aware that Intel has documented hardware-level issues with this NIC model related to TCP-IPv6 checksum offload, which may require disabling this feature:
    Intel Documentation (archived)

Dear will.qiu

I have two 5G routers side by side, the old one and the X3000

  • same PC, windows version, network card, drivers, etc.
  • same SIM card.
  • same cables.

I’m just switching between the above mentioned routers, I cannot understand how is this a network card or a driver issue. This frustrating as I’m able to test both routers with completely different outcomes. Where to test for hardware issues?.

Thank you

11

May we know whether you have tried to upgrade the driver or disable certain advanced adapter features as mentioned before?
Do them work?

This issue may only occur on a small number of devices, so it's possible your old router functions normally, but unfortunately the X3000 no.

The hardware issue means it cannot be fixed via software update, the only way to avoid it is that disable this feature.

12

Nothing helped, The driver is the current 1.1.4.45, and the features were disabled.

Thanks

13

We recommend trying a few different driver versions.
Some Intel users have reported that downgrading to an older version has actually helped resolve similar issues.

If the problem persists after trying a few different drivers, please contact our after-sales support team at [email protected] for further assistance.

I’ve received a replacement router, works as expected. Thanks to everyone involved.
