Windows 10: Windows 10 limiting network speed to 100Mbps

Hi everyone,

So, this thing is driving me crazy.

-I've got a 300mbps internet.

-My network adapter is gigabit capable.

-The ISP router to which I'm connected via a perfectly good cable is also gigabite capable.

However, apparently randomly, Windows 10 limits my Gigabite connection to 100mbps.

Then, after running some commands like ipconfig /flushdns , netsh int ip reset all,netsh winsock reset and stuff like that, my connection goes back to full speed, and my adapter settings go back to 1.0Gbps stats...But this fix only works sometimes, meaning that sometimes I have to repeat these commands and restart the PC a few times to get it fixed.

Anyway, I've got this old notebook running Ubuntu that I always use for these kinds of tests, and guess what, whenever I connect it to the same main router, it gets gigabit speed instantly, using the same cable.

So yes, I'm sure it's a Windows 10 issue.

Things I've tried (literally every possible fix I've found on the internet):

-Changing cable (it's a short distance anyway, before someones asks, like 2m)

-Changing adapter advanced settings (Speed & Duplex) from "Auto Negotiation" to "1.0Gbps Full Duplex". Does't work.

-Uninstalling and reinstalling the network adapter. Sometimes it works, but not for too long.

-Disabling global autotuning level.

-Swapped the network adapter with another one from my wife's computer. Didn't work.

-Tested the same PC using a live Linux CD. Instant Gigabite speeds.

Could you guys please help me out?

Thank you,

M.

Windows 10 Pro Internet Speed Limitation?

Hi guys.
I've had to mark this as unresolved and bring it back up as the issue has returned. I am not sure what it is that is causing this as I haven't installed any program that would limit, manage/handle bandwidth usage.
Below are a few screenshots of my Programs and Features list and the list of Windows Updates:








To also note; I have done a few speedtests and the result is the same as before I reinstalled Windows. (100-144Mbps) After reinstalling, for a few weeks I was getting my full speed. (380Mbps) Then it suddenly capped. My iPhone XR (being connected to my 5GHz WiFi network) gets the full speed.

I have also redone the "tweaks" for trying to remove the limitation as in tutorials on Google. No help. None of these "fixes" actually work. That is to say; updating my network card driver (in this case my TP-Link TG-3468 Gigabit Ethernet PCI card), using Command Prompt with the few commands suggested to use, GPEdit.msc, etc. None of these work. Windows 10 is still limiting/capping my Internet and it is beyond frustrating. Delivery Optimization is also disabled and Limit Reservable Bandwidth in QoS Packet Scheduler is set to 0%.

I should also note that my Private Internet Access VPN is disabled.

Update: Typing this into an elevated command prompt seemed to allow me to use more of my speed, but not 350Mbps+.

I'm assuming it is peak times at the moment.

 

Network card of Giga and shows only 100mbps on network connections

I've set my jumbo Frame to disabled.

Still 100 Mbps... ^^

I've bought a new Network switch of Gigabit and it changed my Network Connections speed to 1 Gbps but still not changed my internet test, it still gives under 100 Mbps.
