Yes. Fiber-optic internet is a completely different technology than DSL or cable internet, and therefore requires a different type of modem. In many cases, you can get the required modem from your internet provider at no extra cost.

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.
