Whenever Microsoft releases a cumulative update for Windows 10, the OS downloads the updates in the background. While the OS downloads the update file, other applications that require internet connection provide bad experience. For example, the download manager tool may take ages to download a file. The browser will not open our favorite web page. These problems occur because Microsoft has configured Win 10 OS to use 80 to 90% of network bandwidth.

The best way to fix the network bandwidth issue in Windows which results in slow internet browsing speed is by changing the QOS settings via the Local group policy editor.

If you’re using Windows OS for a long time, you might know that Pro version of MS OS provides a powerful Group Policy Editor tool. The GPEDIT utility lets you tweak important settings of the OS.

I switched from Windows 7 Pro OS to Win 10. Unfortunately, the home edition users of MS OS doesn’t have the gpedit tool. To fix this problem, I installed this patch developed by a DeviantArt user jwills876.

The patch installs gpedit on Windows 10 home OS. You’ll have to copy the following three files from the c://Windows/sysWOW directory to C://Windows/System32 so that Windows recognizes the Local GPE. Once you move the files, you can run the tool by typing gpedit.msc and hitting the enter key.

Now, follow the below steps to reserve minimal bandwidth for the system processes (svhost, wisvc, etc).

  1. Select QOS packet scheduler entry under the Administrative templates option.
  2. Click Limit reservable bandwidth limit.
  3. Select enable option and set the bandwidth percentage to any value below 30%.
  4. Click on the save button.
  5. Reboot the computer or laptop.

Here’s a screenshot which explains the steps mentioned above:

If the QOS bandwidth value is set to an optimal value, follow the below steps to fix slow internet speed issue in Windows 10 OS.

Change Ethernet card: For some reasons, the new gigabit Ethernet card on my PC didn’t work with one of my ISP’s CPE device. I paid 20 USD for 3 Mbps connection but network speed test results showed the broadband connection speed as 10 to 20 KB/sec. I bought a third-party LAN card and installed it on the PC. The connection speed was up to 300 KB/sec.

Updating WiFi driver: Outdated WiFi hardware driver caused frequent connection drops when on my laptop running on the Ubuntu OS. I updated the Realtek Linux WIFI driver to fix the inconsistent connection problem. If you use Windows 10 OS, make sure that you update driver software regularly with Snail Driver or a similar tool.
