There are many factors that can influence internet speed. In many cases, restarting your router will resolve speed and connectivity issues. Other factors, such as peak usage times and speed throttling can also cause temporary speed issues.

According to the FCC, 93% of households have access to three or more providers. In many areas, a cable, DSL, satellite and possibly fiber-optic provider may be available. You are unlikely, however, to find multiple providers of the same internet type, such as two cable providers, in the same location because operating expenses in an area already served by another provider can be too high to be profitable.

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.
