The Internet is only as good as its modem. Without the right modem, you will miss out on the opportunity to experience the highest level of speed and connectivity that your Internet service provider has to offer.
In 2017, Spectrum achieved a great feat through the rollout of its DOCSIS 3.1. Launching this latest modem meant customers could enjoy superfast internet speeds up to 10 Gigs without subscribing to fiber internet connections.
All Spectrum-approved modems must have the DOCSIS 3.0 or DOCSIS 3.1 interface and should be able to withstand internet speeds greater than 300 Mbps.
Spectrum Compatible Modems
Usually, Spectrum Internet® subscribers are not concerned about the compatibility of their modems because when new customers request equipment installation, the company sends them a new Spectrum-authorized modem for free. Subscribers are only required to pay a small sum of $5 per month along with their monthly Internet charges for the usage of this Spectrum-authorized modem.
However, if you already have a modem at your home and would like to save that little extra money every month, it is necessary to check whether or not you have a modem compatible with Spectrum Internet.
A rule of thumb should be to check if the hardware sitting at your home is a modem, router, or gateway. There are two kinds of modems; cable modem and DSL modem, so for people with limited technical skills, a good identification marker will be to check by counting the number of ports.
How to Identify the Modem/ Router at Your Home?
Usually, a DSL modem will have at least three ports. One port is for your telephone line, the second is the Ethernet (LAN), and the third is for the power connector. In contrast, a cable modem will have one threaded F-connector port to connect it to the primary cable connection, a second port for the Ethernet, and a third port for the power supply.
A standard home router will have four or more LAN Ethernet ports, one WAN Ethernet port, and at least one or two USB ports. LAN ports can are to connect your wired devices to the router. For example, your desktop or laptop. A typical WiFi router will also have antennas as its distinguishing feature.
On the other hand, a gateway supports the functions of both; a modem and a router. Hence, it has multiple Ethernet ports, a threaded F-connector port, a port for DSL cable connection, and single or multiple USB ports. In layman’s terms, if that tech box in the corner of your living room looks loaded, it is gateway hardware.
After you have successfully managed to identify your device, you must proceed to establish whether or not you have a Spectrum-approved modem.
Only the modems that can withstand the maximum bandwidth provided by your internet carrier can be used, and that’s why most cable modems do not work for DSL broadband internet. Similarly, a DSL modem will not work for fiber internet.
Spectrum Internet and DOCSIS Modems
As a Spectrum Internet customer, you will need a DOCSIS cable modem. A Data Over Cable Service Interface Specifications (DOCSIS) is the specified interface for cable modems. The first version of DOCSIS was launched in 1998 and could distribute the data by cable TV operators to connected devices like computers and televisions.
Over the years, DOCSIS modems have evolved. Today the most used versions are DOCSIS 3.0 and DOCSIS 3.1. The main difference between these two newer versions is the maximum internet speed that they can support.
| Modem | Download Speed | Upload Speed |
|---|---|---|
| DOCSIS 3.0 | 1 Gbps | 100 Mbps |
| DOCSIS 3.1 | 10 Gbps | 2 Gbps |
The maximum speed available to Spectrum Internet users is 1 Gbps (wireless speeds may vary). Therefore, any modem with the DOCSIS 3.0 and DOCSIS 3.1 interface listed under Spectrum-approved modems will be perfect for the connection.
