Hub 5 update broke 2.5Gbps port

A week or two ago, my Hub 5 did a system update (in the middle of an online game, as an added bonus) and when it restarted the 2.5Gbps ethernet port was essentially useless. My PC is plugged into this port and was unable to even reliably connect to 192.168.0.1. There was still some data coming through - I was able to remain on a discord call and people could hear me just fine, but all incoming voice was a garbled mess so I guess I had upload speed but virtually no download.

Tried a different cable, same result. Switched to a 1Gbps port and everything works fine, but since my download speed is around 1.1Gbps I'm not really ok with the only port I have capable of handling that speed not functioning.

A factory reset fixed the issue, but the Hub 5 updated again last night and my 2.5Gbps port is again broken.

Any idea how to stop this from happening? I can do another factory reset but I don't want to have to factory reset my router after every update. Current software version is LG-RDK_7.6.15-2306.5.

    I wonder if connecting a PC with a 2.5Gb by 0.25M cable will be fine....

      Why would that make any difference?

        LOL I think the logic is a shorter wire could be more energy efficient. 😊 

        When our new kit in a data centre had it, we saved 6% energy and that includes the days systems were stuck on 10Mbps negotiation rate. It doesn’t factor in the 2 150 mile round trips wondering what was going on. It was the build config not applying correct on a 64 port Cisco switch hence I bet this is similar. We were baffled as the config showed it was off so it was not our first thing to check. Given the switch cost about £70 a year to run (before rates were quite as high as they are now), it was about a fiver in money. Hardly life changing but I guess it adds up around the world. If only it worked 

        the 6% energy saved cost me my sanity 🙂 had devices stuck at gigabit speed maybe it would have saved even less, or perhaps the slow speed meant the usage was elongated.

      Well it was going to happen if VM didn't do anything

    Any update on this or is everyone still unable to use the 2.5Gb port

      "Anyone managed to utilise their 2.5Gb port on Hub 5" my Hub5 works ok after the update. In modem mode connected to a UDM Pro router at 2.5G. Stats from my router show it’s working ok.

    There is another post about this. the use of a managed smart switch disables EEE - Energy Efficient Ethernet which is what causes the problem. 

    I upgrade a 8 port un-managed 2.5 Gbit switch to a Smart managed one back in March & have had no problems since. 

    You can get a 2.5 Smart Switch on Amazon for £66, but to take full advantage the rest of your network components need to rated at 2.5 Gbit. I got caught out by this for the first 18 months, after I renewed I made enquires to get the full speed.  -

    Here's a guide on how to disable Energy Efficient Ethernet (EEE) settings on your PC, which might help resolve connection issues without needing to buy a managed switch:

    Note: These steps are for Windows 11 version 23H2. If you're using a different Windows version, the process might vary slightly.

    1. Right-click the Windows button.
    2. Select "Device Manager."
    3. Expand the "Network adapters" section.
    4. Find your Ethernet network card (e.g., Realtek PCIe GbE Family Controller).
    5. Right-click on it and select "Properties."
    6. Click the "Advanced" tab.
    7. Look for energy efficiency options like:
    - Energy Efficient Ethernet
    - Green Ethernet
    - Power Saving Mode
    - Energy-Efficient Ethernet (802.3az EEE)
    8. For each energy-related option, select it and change the value to "Disabled" in the dropdown menu.
    9. Click "OK" to apply the changes.

    Your network connection may briefly disconnect and reconnect within 5-15 seconds after making these changes.

    Important notes:
    - Not all network adapters support EEE configuration, so you might not see these options.
    - While this solution can help with network issues, it also means your network adapter will consume more power when idle. However, this increase is likely less than the power consumption of an entire managed switch.
