Windows 10: Ethernet speed suddenly went from 300 mbps to 0.4 mbps

Until today everything was fine but today suddenly my computer won’t get more than 0.4mbps. I checked on my phone and laptop and they still get between 250mbps - 300mbps. I tried to do everything I know but nothing worked, its so bad that I couldn’t even send this question from the computer and I had to use my phoneIf anyone can help me I will really appreciate it

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?

 

Ethernet Link Speed at 10 Mbps

Hello, I have been having some slow ethernet. I went through the settings and in the properties for mt connection it says the link speed (transmit/receive) is at 10/10 Mbps. When I try wifi its capped at 520 Mbps but its very unstable most of the time, so I want to use ethernet. Here is some information about my situation:

• Using a Cat.6 Cable
  
• Tried reinstalling ethernet drivers
  
• I tried resetting the network through the settings
  
• I tried all of the steps on this page Fix Ethernet connection problems in Windows - Microsoft Support
  

I would really appreciate additional ideas on how to fix this problem.

Thanks

 

Ethernet Link Speed at 10 Mbps

Hello Marco,

I actually tried that already, but I tried it again (For me the option is called Speed & Duplex) I set it to the max value of 1.0 Gbps. I also disabled the 'Auto Disable Gigabit' option and it still shows a link speed of 10/10 (Mbps) and when I run a speed test both values come in at just under 10 Mbps.

Anything else you suggest?

Thanks
