Your modem and router need to be able to handle the bandwidth and speed of your ISP’s network to reach their maximum potential. First, you need to know the speed of your plan. Many ISPs offer Gigabit internet in addition to packages with lower speeds. For example, if you are on a 400 Mbps plan, you’ll need a modem and router designed to handle that speed. Your ISP will ensure you have the right equipment for your plan if you rent. If you are purchasing the devices yourself, check with your ISP for help choosing ones that can handle the speed.
