Three best modems
Modems are fairly simple machines, helping to connect your devices to the internet, but that doesn't mean they don't come with their share of varieties and features. While your internet service provider (ISP) may have given you a modem, you are most likely paying monthly rent on it that can quickly get expensive. Your modem needs to be capable of supporting the download speeds of your internet service, especially if you are paying for a high-speed gigabit service. Some modems have built-in routers so you don't need an additional device to deliver WiFi. In this concise guide, we break down the basics of modems so you can find the right model for your budget and your internet needs. Our top recommendation is from Motorola - it's expensive but if you're paying for upgraded internet speeds then you need a modem like this to match.
Considerations when choosing modems
A modem is a major factor in your internet speed. It doesn't matter how fast your ISP claims your internet service is if you don't have a modem capable of supporting a fast enough upload/download speed. You should also consider whether you plan to purchase a separate router or will opt for a modem/router combo.
Choosing a modem for your internet speed
When shopping for a modem, take note of its upload and download speeds to ensure that they match or exceed the speeds offered by your ISP.
Modem/router combo vs. separate units
Many modems have built-in routers, eliminating the need for an additional unit to provide WiFi in your home. While this is convenient, wireless routers are upgraded more frequently than modems, so you may be sacrificing speed for simplicity.
There are two main modem speeds: basic high speed and gigabit speed.
If you are paying your ISP for gigabit-speed internet, you need a gigabit-speed modem to keep up with it. Gigabit-speed modems, called DOCSIS 3.1 modems, are the current standard for gigabit internet services. For basic high-speed internet, you need a DOCSIS 3.0 modem or a DOCSIS 3.1 modem, which is backward compatible with lower speeds.
If you use a landline phone, you will need a modem that offers telephone service.
You should also confirm with your ISP that the modem you are considering is compatible with their service.
Just as you need to compare the speed of your modem with your internet service, you should also consider the speed of your Ethernet cable.
A basic high-speed modem typically costs $50 to $100 and usually offers few additional features. For a gigabit-speed modem, you will usually need to spend between $100 and $350. These modems may have features like built-in routers or USB ports.
Q. How do I find out my internet speed?
A. You can call your ISP or log into your ISP account to see the speed of your internet service.
Q. Why should I buy a modem rather than use the modem provided to me by my ISP?
A. There are two main reasons. Your modem may be out of date, and you are likely renting this modem from your ISP for a rate that costs you more per year than a new modem would.
