Windows 10: Windows 10 upload to TrueNas capped at ~100 Mbps despite 1 Gbps hardware - reverse iperf ok

Hi, I've been trying to figure this out for quite some time and was unable to make any progress wanted to see if there was anyone who could help me figure out what's wrong here.

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

 

1 Gbps internet

I recently upgraded to 1 Gbps internet from 100/100 Mbps. Both of my computers run Win 10 Pro 64 bit systems. They are both connected via wifi and both have recorded speeds at around 100 Mbps using wifi. If I use an ethernet cable directly from the router
I get almost 987 Mbps. Why the big discrepancy from wifi to hardwired? Can you buy a better wifi card or something to make the wifi match or be as close as possible to the ethernet connection?

 

Ethernet speed capped at 100 Mbps

I have a Lenovo Legion T5 28IMB05, and my Ethernet connection is capped at 100 Mbps.

Things I have already tried and didn't work:

• Switch to another cable. Originally, I had a CAT5e and as my speed was capped, I bought a CAT6. It didn't help (though I'm still using it)
  
• Force the driver to use 1000 Mbps full duplex
  
• Try my cable and router with another PC. It works
  
• Try to boot from a live USB running Ubuntu 21.10. It also didn't reach full speed
  

The funny thing is that if a plug a USB Ethernet adapter (TP-link UE330), it reaches gigabit speeds with that cable and router; and then if I reconnect the cable to the Ethernet port on my PC, IT WORKS at gigabit speeds for as long as I have the PC turned on. When I restart, it goes back to 100 Mbps.

As of course, I prefer not to have to depend on a USB dongle to reach full speed on my network, what can I do?
