Fiber internet may also be an internet option, but this technology is typically found in larger cities. Those living in rural areas not serviceable for cable, DSL or fiber internet may find satellite or fixed wireless internet to be their only options.

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.

Wi-Fi extenders are handy when your router can’t project a strong signal to everywhere in your home that you need it. Your internet provider may offer Wi-Fi extenders for an added monthly cost, or you can purchase one online or from most electronics retailers.
