What internet providers are available at my address?
No matter where you live, your address is likely serviceable for satellite internet from providers such as HughesNet and Viasat. You will probably also have the option of at least one cable provider, such as Cox, Spectrum and Xfinity, and DSL providers such as Frontier and Verizon. Roughly a third of households will be eligible for fiber internet from AT&T, CenturyLink, Windstream or other providers.
Is my internet speed being throttled?
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.
Do I need a phone line for broadband?
The only broadband internet type that requires a phone line is DSL and dial-up, which use phone lines to deliver service. Other internet types, such as cable, fiber-optic and satellite, require no phone line for broadband service.
Do I need a new modem for fiber internet?
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.
