Windows 10: Windows 10 Upload speed capped at 100 Mbps

Hi,


For some reason my upload speed is capped at 100 Mbps, it should reach 250 Mbps. I tried restarting in Safe Mode with network, and the speed was as it should be, but in normal mode it isn't. What else can I do?


What I tried:
1. Uninstall all network drives, and reinstall them;

2. "netsh int tcp set global autotuninglevel=normal"

3. "ipconfig /release" + "ipconfig /renew"

4. "netsh int ip reset resetlog.txt"

5. "netsh int tcp set global autotuninglevel=disabled" now it is set back to normal

:)

 

Upload speed capped on windows 10

Okay so, for some unknown reason, my computer and brand new laptop both running on windows 10 home, are capping my upload speed at 7.9mbps (exactly 0.6mbps from my router's upload sync speed). At first it may seem normal to be running slightly lower than
the upload sync speed, however on all my mobile phone devices, speed tests show that my phones are reaching between 9-10mbps. The exact same speed tests (And other speed tests) on my computer and new laptop show that the upload speed is being capped at 7.9mbps.

The router is new. I have recently had the line fixed so there's no issue there. The fact that my new out of the box laptop is also capping it makes me believe there's no malware or virus issue going on here. The only thing I have narrowed it down to is
that Windows itself is capping the speed somehow. I have also tried connecting to the router via ethernet cable however the speed is still capping at 7.9mbps. It is ALWAYS capping 0.6mbps under the sync speed and I'm not sure what is causing it.

I'm using ADSL like you suggested, I'm also using the talktalk wifi-hub, however I have also tried with the talktalk super-router and am receiving the same issue. Upload speed is being capped at 7.9mbps.

Nope it uses Wi-Fi. I have tried taking Data off incase it was also getting into there to increase the speed, however even so, it shows that it has a greater upload speed and can seemingly utilize all of the upload speed it is acquiring from the router,
whereas both my computer and laptop cannot. They are both capped at the exact same speed.
