Windows 10: Slow Ethernet Speed

My computer is getting slower internet speeds on the same network as other computers. When running a speed test on my laptop on speedtest.net it shows download speeds of 500+ Mbps on the ethernet cable. Now taking that same ethernet cable and plugging it into my desktop I am only getting internet speeds of 250 Mbps so it is not the cable or the router. The motherboard is an "MSI Z490-A Pro" gaming and the Ethernet is "Realtek PCIe FE / GBE / 2.5G / Gaming Ethernet Family Controller" so it should support up to a gigabit network connection which is far above what I am getting. I have checked to make sure all the drivers are installed and updated to the latest versions but this did not help. In the driver network properties, speed and duplex is set to Auto-negotiation, I have also tried setting it to 1.0 Gbps full-duplex but this did not help so I changed it back to auto. I also have flow control set to Rx & Tx Enabled. When running the tests no programs were using the network in any major way. I have tested the network on both the speedtest by ookla app, I have tested on their website, and I have tested on the spectrum site using the ookla test. Motherboard bios is also updated to the latest version.

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.
  

Hope the information is helpful. Feel free to write to us for any other assistance with Windows, we’ll be glad to assist you

 

Ethernet internet speed is slow

Hi JadenLay and thanks for reaching out. My name is Joseph. I'm an independent advisor. I'll be happy to help you out today.

I would suggest you refer to the below steps and check if it helps to resolve the issue.

Solution 1. Refresh Network.

1. Open CMD as an administrator mode.

2. Type in the following,

ipconfig /release <Press Enter>

ipconfig /renew <Press Enter>

ipconfig /flushdns <Press Enter>

ipconfig /registerdns <Press Enter>

nbtstat -rr <Press Enter>

netsh int ip reset all <Press Enter>

netsh winsock reset <Press Enter>

3. Check to see whether or not the problem has been resolved.

Solution 2. Disable Large Send Offload (LSO).

If you’re experiencing slow LAN speed on your Windows 10 PC, the issue might be a Large Send Offload feature. In order to solve the problem, you just need to disable this feature by doing the following:

1. Press Windows Key + X and choose Device Manager from the list.

2. Double-click on your Network Card and click on the Advanced tab.

3. Select Large Send Offload V2 (IPv4) and set the value to Disabled.

4. Do the same for Large Send Offload V2 (IPv6).

5. Click OK.

Solution 3. Change your DNS settings

If you’re having issues with slow LAN speed, the problem might be your DNS.

This issue is usually related to your ISP and its DNS, but you can always change your DNS. This process is relatively simple, and you can do it by following these steps:

1. Type Network and Sharing Center. Select the first result.

2. Go to Change adapter settings, right-click the Ethernet network interface, and select Properties

3. Select Internet Protocol Version 4 (TCP/IPv4) and go to Properties.

4. Select the “Use the following DNS server addresses” option and type your preferred and alternate DNS addresses.

5. You can use Google’s Public DNS addresses 8.8.8.8 and 8.8.4.4, OpenDNS addresses 208.67.222.222 and 208.67.220.220 or other DNS addresses.

6. Check to see whether or not the problem has been resolved.

internet speed slows down

Hi Barry,

Having an outdated Ethernet card driver, faulty Ethernet cable, and outdated modem firmware are a few factors that affect the internet speed. If you have a spare Ethernet cable, then I suggest replacing the one you're using to determine if its the cable
that's causing your internet speed to slow down.

You may also update the driver of your Broadcom Gigabit Ethernet card. If the issue is triggered by having an outdated driver, then you can have Windows to search automatically for updated driver software to help fix and address the problem. Kindly check
out Update drivers in Windows 10 and follow the steps provided in updating the drivers.

If the above steps won't help, then I recommend that you get in touch with the WOW support team to check the modem. Since they're your Internet Service Provider, then they are the appropriate support to look into the modem and perform necessary updates or
troubleshooting on the device.

Should you have further queries, feel free to post back.

Regards.
