How to test if Xfinity is throttling Netflix and other services with a VPN

To detect if your ISP is throttling your internet

To detect if your ISP is throttling your internet connection, you will need a VPN.

A VPN is a Virtual Private Network that helps you hide or encrypt your data from your ISP.

Thanks to the VPN, ISPs will not be able to detect the traffic coming to and from your connection, which is useful if you’re experiencing a slow connection when streaming or downloading movies.

Once you’ve selected your preferred VPN, run a speed test on your connection twice: once with your VPN turned off and once with it turned on.

If you notice discrepancies between the two tests, your ISP is likely throttling your internet connection.

However, this test is not conclusive; it only helps when your ISP throttles your connectivity for specific websites or activities.

In addition, there may be other reasons you may experience slow connectivity, such as paid prioritization, network congestion, or data caps.
