1. The Internet Speed of Your Package

All routers and modems display the amount of internet speed they offer. You must pick a modem that can efficiently handle the offered speed. The speed you get must match with the speed offered by Optimum.

Be precise in what you require from the modem in terms of coverage area. The range for smaller spaces is different than those required by bigger spaces.

The modem you pick depends largely on the amount of people using that network. The number of devices connected to one network impacts the overall speed offered by the modem. If there is only one device to stream at a time, you can consider buying a modem with standard features. But if the requirement is more, you must purchase a modem backed with multiple rich features. You can check this article on best router for multiple devices.

4. Speed
