Please try my suggestion. It will work.

Really!? What rule would that be, as I seemed to have broken it repeatedly without any effort - and all without the help of some random “TCP optimiser”.

Jeez it’s not even April 1 🤣

Some applications manipulate registry settings to suit there own requirements. Often it’s the one that decides how many multiple connections that windows can make. I tend to find for people reporting speed of 250 - 350 it’s set to 2. TCP optimizer sets it to 10. It fixed my issues.

Not needed on a clean factory install of Windows, so I suspect some broken third party security software. Third party security software is now becoming the problem, even blocking Microsoft's security updates and making the computer less secure.

Completely agree. All tcp optimiser does is restore things to default settings.

I had the same problem as the poster when I upgraded to 1 gig Speedtest was stuck at around 280. I am an analyst by trade so obviously did further digging and solved my problem.

I was however able to replicate on my brothers laptop when he moved in with me.

Was literally down to registry settings.

Intersting you say about that. You also but there no meation of you network cable connection. Now I going say something that could be dead end but go with it for moment.

On SB2 on Windows browser go to google and type in What my ip and make note of that IP. Then do very same thing on SB2 but this time with Ubuntu webbrowser. Is that pubic IP the same?

Don't publish the IP on thinkbroadband I am just curious if they are same.

Just following your helpful suggestion to update firmware on Surface Dock 2 and found that the update is for the first version of the Dock because , "Surface Dock 2 ... receives updates automatically via Windows Update or by using Microsoft Endpoint Configuration Manager or other MSI deployment tools. " See https://docs.microsoft.com/en-us/surface/surface-doc...

But tx for the tip. I appreciate that that information was a bit far in to spot.

The real question is what software had you and your brother both installed that screwed up your W10 network settings so badly?

As said, a clean/vanilla install of W10 (on sufficient hardware / decent NIC) will easily handle gigabit connections without adding further tuning software or messing with the registry.

What firmware version is your dock running?

Edit:

Microsoft Surface Update History (all devices) is summarised here.

Current Surface Dock 2 driver version looks to be 20.054.xxxxx.0 or 20.062.26674.0 (for WMI support) based on this update page

I wonder if both your laptops came from a retail company that pre-installed some security product?? The names McAfee or Norton spring to mind.
