Cable Modems

Cable modems are network devices that create links between local networks in homes or businesses and service provider public networks. They support a variety of communication protocols and are compatible with many different ISPs. With the selection of networking and Wi-Fi® accessories offered by Staples®, it's easy to find a cable modem that meets your communication needs.

Cable Modems Deliver High-Speed Network Access
Almost all these products support the DOCSIS communication standard, which ensures compatibility with a broad range of internet service providers. Up to 8 upstream and 32 downstream channels deliver up to 1Gbps download speeds, fast enough to provide high-definition video streaming to multiple devices, lag-free gaming, and quick access to web resources. Many devices also have built-in support for voice communication, so users can take advantage of cable company bundle deals that include phone service.

Cable Modems Are More Than Communication Links
Many of these products have additional networking features. Models with built-in routers have Ethernet ports and Wi-Fi® support, making it simple to access the internet from multiple tablets, desktops, network-enabled appliances, and media devices. Modems with Wi-Fi include features such as dual-band communication and beamforming technology that extend range and improve wireless transfer speeds and signal reliability. Some models also have USB ports. Use them to share a printer or external hard drive between computers.

Do All Cable Modems Work With Your Cable Service?
While most modems conform to industry standards and are compatible with the majority of ISP networks, many cable providers list approved communication hardware on their websites. In most cases, these devices have been tested for compatibility with ISP networks. Get the best cable modem performance and ensure service technicians can help solve technical issues by choosing a recommended product.

Are Cable Modems and Routers the Same Thing?
Modems and routers have similar functions: They transfer data between devices. However, modems translate signals between two different formats, in this case, cable communication and IPv4 or IPv6, the standard protocols of the internet. Routers connect multiple devices that use the same communication protocol. Accessing the internet from multiple devices using a cable provider's network requires the capabilities of both devices, making a cable modem with a built-in router an attractive option for most homes and businesses.

Are Cable Modems Secure?
Many modems, especially those with router features, have security options that help protect home or business networks and the systems that connect to them. Firewalls with stateful packet inspection and network address translation capabilities guard against malware threats and unauthorized access attempts. WPA and WPA2 encryption provides password protection to Wi-Fi networks, and parental controls help parents manage their children's internet access.

Are Cable Modems Hard to Set Up?
Most of these devices require just a few physical connections and come with software that guides users through the installation process. Enabling the cable connection may require a phone call to an ISP customer service representative. Models with router capabilities take a little computer know-how to create custom configurations, but manufacturers pre-configure most to provide secure network access right out of the box.
