Windows 10: Ethernet speed 1/3 what it should be

To preface this-I have gigabit, ethernet works on other laptops 950 Mbps up/down like normal, yet when plugged into my desktop it never goes above 300mbps. I have all ethernet settings default, speed is listed as full-duplex 1gbps, I don't know what's happening. I've followed every guide I could find. I've even bought a gigabit network card with the same results. Does anyone have any idea what's going on?

IP configuration not valid - interference from ethernet adapter?

Solution 1: No Internet Access In Windows 8.1or Windows 10

Step 1:

Go to Device Manager → Network adapters.
Step 2:

Expand it (Network adapters).


Step 3:

Select your network adapter


Step 4:

Right click on your wireless network adapter or Ethernet adapter and then tap “Update Driver Software”.
(in this case your network adopter is Ethernet adopter so tap your Ethernet adapter)
Step 5:

Now on a new window you will need to click on “Browse my computer for driver software”.




Step 6:

Then select “Let me pick from a list of device drivers on my computer”.



Step 7:

Now choose the “Manufacturer’s drivers” from the list of two and then click next.



Step 8:

After the completion of the process just restart your PC and check if the problem is solved or not. If not, goto solution 2.



Solution 2: No Internet Access In Windows 8.1,windows10

Step 1:

Open command prompt.
Step 2:

Just go on hitting the enter after typing the each command.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disable
netsh int tcp set global rss=enabled
Step 3:

Now to check if the settings are disabled type:
netsh int tcp show global
then hit enter.
Step 4:

Now the thing left is just rebooting your system and just check if the problem is solved or not and just give feedback.*chuckle*Thumbs

 

Limited Ethernet speed

I've reset my router. That didn't help.

I've reset network in Windows settings.

After Windows restart Ethernet speed was 100% but it started to brake connection and automatically connect again every few minutes.

After another Windows restart my Ethernet speed is again around 10% of what it should be until I fix it manually.

Also disabling and enabling Ethernet adapter in Control Panel\Network and Internet\Network Connections stopped fixing this problem.

Only unpluging and plugging in Ethernet cable works as a manually fix.

 

Slow Download Speed

Hi,

Thank you for posting your query in Microsoft forums.

• I would suggest you to test the speed using any of the speed test website or app to confirm the upload and download speed.
• I also suggest you to reset the wireless router to check if that helps.
  
• You may plug in the Ethernet cable if available and check the speed.
