How to fix Windows 10 Wi-Fi lag spike issues for good

One issue Windows 10 users have often been vocal about is the Wi-Fi lag that often tends to spike beyond appreciable limits, leading to a below-par internet browsing experience each time that happens. That again is something that is very inherent to the way Windows update works given that it uses a peer2peer method of propagating the update among the masses.

That way, your PC might very well serve as a download location for other users to be provided the update. However, any drop in upload or download speeds might not be too perceptible with a fast internet connection though things can truly become a chore during days when your internet connection isn’t at optimum.

However, like with most other problems, there sure is a solution to the issue. And it’s simple and quick too. So, let’s get started right away.

Ways to deal with Wi-Fi lag spikes in Windows 10

1. Turnoff peer2peer system

As has been stated above, the peer2peer system is the reason Wi-Fi lag spikes. So the most logical method to deal with it will obviously be to turn it off. Here is how you do it.

1. Go to Settings > Update & Security.
2. In the Windows Update page that you are led to, select Advanced Options.
3. In the Advanced Options page, select Delivery Optimization along the bottom of the page.
4. Here, toggle Allow downloads from other PCs to Off.

While the above process has been designed to ensure you get your updates over even an unreliable internet connection, or when speeds aren’t that great, toggling the above setting off will still make sense if you find yourself at the receiving end of the above phenomenon.

2. Turn off Background Intelligent Transfer System

Just in case the above failed to realise the desired outcome, here is another method that disables Windows Update as a whole. Hence, this makes for a reliable method of dealing with the Wi-Fi lag spikes though what also needs to be kept in mind is that this will deprive the PC of key updates that Microsoft makes available from time to time to patch critical vulnerabilities.

This should effectively kill BITS forever so that the service won’t start again even when the PC restarts. However, as has been stated above, the user’s discretion is advised when turning off BITS. Also, downloading the updates manually is highly recommended to ensure protection against all emerging vulnerabilities.
