Question Slow downloading on 1 of 2 PCs with all the same hardware and drivers ?

[ToolPunkXS]

I built x2 PCs a couple years ago with ALL of the exact same hardware. Both are running fully updated versions of windows 11 and the same exact updated drivers. Yet, one of the PCs, downloads from the internet at only 3/4 of the speed. I thought that maybe the windows firewall could be to blame so i turned that completely off and no change. I dont even know what to think at this point.

Are both of these PC on the same type and length of wire for access? Could either of the data cables be running in parallel with AC power?

What does speed say under ethernet status, 1.0Gbps or 100Mbps?

Sometimes can come across network cables haven't had an end or ends crimped properly. It's happened to me, luckily i had a crimping tool and just recrimped rj45 plug so wires are making proper contact. Just 1 out of the 8 wires in a network cable not making contact will default to megabit. Gigabit requires all 8.

Try a different network cable.

Both PCs are using the exact same type and length of cable (cat6/10ft). Both just run across the desk to the router.

Ethernet status on both PCs is "1.0Gbps". An internet speed test on all my PCs returns 450 down and 35 up. On the troubled PC it returns, 45 down and 35 up. I will try another cable in the meantime but if you have any other ideas, thank you.

Tried a different cable and no changes.

I tried all of the below from a Microsoft thread and still no changes.

Enable WWAN and WLAN services, these services are essential to run the Wireless and wired connection perfectly.

- Open Services (Press Windows key + R then type in services.msc then click OK)

-Look for WLAN Autoconfig and WWAN Autoconfig> Right-Click Properties and set it to automatic (If it's already set to automatic, right-click then click stop then start it again)

-Restart the PC and check

If the issue persists, run the following command in Command Prompt (Admin). Follow the steps below to do so.

These sets of commands will reset the internet connection and re-calibrate the internet settings you have.

Press Windows Key + X.
Click on Command prompt (Admin).
Type the following commands, and hit Enter after each command:

netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Reading more about the problem I noticed others suggesting to instead run the command as "netsh int tcp set global autotuninglevel=normal" instead of as "disabled". This fixed the problem instantly!

Since running the originally suggested "disable" command did nothing and setting it to "normal" fixed it, I assume that some where in the threads of time this setting got set to disabled by who knows what.
