Hi All,

Hoping someone can give me some insight into my issue. I am on Skinny Fibre max/max.

I have a desktop and Laptop at home. My issue is that I get very slow speed on the desktop as appose to the laptop. I am using speedtest.net as the bench mark for the tests.

When I plug my laptop via ethernet into the Edgerouter X I get the below speeds

When I plug my desktop via ethernet into the Edgerouter X I get this as the download speed
As you can see the download speed seems to be much lower but the upload speeds is about right.

Now if I run the CLI version of the speedtest I get this which matches the laptop speeds.

Things I have tried so far:
- Changed network cable
- I use Edge so tried Chrome and Firefox
- Disabled anti-virus
- Removed ethernet drivers from device manager
- Re-installed Windows 10

None of the above has helped sadly.

Does anyone know why would my browser show slower download between the two devices or anything else I can try?

Realtek Ethernet by any chance?

Try booting up in a live Linux distro. But my bet is it is the crappy TCP Scheduling that Windows has. Windows 11 I find is a little better at this.

Also run this in an administrator powershell window and reboot:

netsh int tcp set global autotuninglevel=normal

Using the browser test or the Windows app? There is a difference in results, with app being better.

OP is trying to fix browser speeds

It is worth mentioning that browser speed tests are limited. If the CLI shows max speed, then nothing on the system itself. The app may just confirm that.

Yes thats correct its Realtek Ethernet

I downloaded ubuntu iso and did a live test and the speeds are good, so the issue maybe related to windows and drivers?

I didn't actually think there was a difference between the app and broswer. To be fair I should have tested that as well since the CLI was different.
You are correct the speeds once again is great with the app. So i wonder why its only affecting my browser and does it affect browsing / streaming ?
