How to Select a Modem

What’s a modem?

A modem, short for modulator-demodulator, serves as a bridge between your home network and your Internet Service Provider (ISP). The primary function of a modem is to convert digital data from your computer or router into analog signals that can be transmitted over phone lines, cable systems, or fiber optics, and vice versa. This conversion process enables the communication of data between your local network and the wider internet.

Types of modems:

1. DSL modems: Used for Digital Subscriber Line (DSL) internet, these modems connect to phone lines.
2. Cable modems: These modems connect to the internet via the same coaxial cables that deliver cable TV.
3. Fiber optic modems (ONTs): Used with fiber internet, these modems provide the fastest internet speeds by using light to transmit data.
4. Satellite modems: These are used for satellite internet, which is often available in rural areas where other types of internet might not be.

How do I choose the right modem for me?

There are a few important things to consider when you’re trying to choose the right modem for you.

1. Service provider compatibility: Before buying a modem, make sure it’s compatible with your service provider. Most ISPs provide a list of compatible modems on their website (see Lightcurve’s list of approved modems). Using an incompatible modem can result in poor performance or no connection at all.
2. Internet speed: Modems have speed ratings, and it’s crucial to choose one that can handle the maximum speed offered by your internet plan. For instance, if you have a gigabit internet plan, you need a modem that supports gigabit speeds.
3. Channel bonding (cable modems only): For cable modems, channel bonding refers to the number of channels the modem can use simultaneously. More channels mean better performance and higher speeds. For example, a modem with 32 downstream channels and 8 upstream channels will perform better than one with 16 downstream and 4 upstream channels.
4. Built-in router: If you prefer to have fewer devices or need a simpler setup, a modem with a built-in router might be a good choice. However, standalone modems paired with separate routers often provide better performance and flexibility.

When should I upgrade my modem?

Upgrading your modem can significantly enhance your internet experience. Here are some signs that it might be time to upgrade.

1. Slow internet speeds: Older modems may not support the higher speeds offered by newer internet plans. If you notice a significant drop in internet speed and your ISP has confirmed that the issue is not on their end, your modem might be the culprit. 
2. Spotty connection: A modem that frequently loses connection or needs frequent resets might be failing. Upgrading to a newer model can provide a more stable connection.
3. Outdated technology: If your modem uses an older technology standard (like DOCSIS 2.0 or 3.0), upgrading to a newer standard (like DOCSIS 3.1) can improve performance and future-proof your network.
4. Your service provider is upgrading their service: If your ISP has upgraded their infrastructure and offers higher speeds or new services, you might need a new modem to take full advantage of these improvements.
5. More devices in the home: Modern households often have multiple devices connected to the internet simultaneously. If your old modem can’t handle the increased load, an upgrade can provide better bandwidth management and performance.

Investing in the right modem and knowing when to upgrade can make a significant difference in your internet experience, ensuring you enjoy fast, reliable, and uninterrupted connectivity.
