If you suspect your slow speeds are the result of your internet provider throttling your connection, the easiest way to determine if you’re being throttled is to perform two speed tests. Run the first test on your regular network, then run the second one on a VPN. If the two speeds are drastically different (and the VPN test was higher), your internet provider may be throttling your speeds.

Downgrading services or cutting extras, such as Wi-Fi extenders or premium tech support, can lower your monthly internet bill. You can also try to negotiate with your internet provider for a lower rate. Switching internet providers and bundling internet with other services is another common way to lower internet costs.

Download speeds of 25 Mbps and above are considered broadband speeds, and can handle most online activities including streaming and gaming. For households with multiple devices using a Wi-Fi connection, speeds of 100 Mbps and higher are likely to offer a better online experience. Learn more about what speeds are best for your home.
