A cable modem router acts as an access point for cable internet and a network router, allowing multiple computers to share internet access. Wired models offer better speeds and security, while wireless models are simpler but slower. Preconfigured options are available, but buying your own allows for customization. Prices range from $35-$75.
A cable modem router is a device that not only acts as an access point for cable Internet access, but also acts as a network router. The cable modem’s built-in network router allows more than one computer to share Internet access by routing traffic to two or more computers in a single location, such as a home or office.
A router can be purchased separately from a cable modem and connected in tandem, but a cable modem router is more manageable, more efficient, and typically easier to set up. These devices come with software that allows the user to access the configuration tables. Through these tables you set the parameters that allow the modem to successfully connect to the Internet cable signal sent over the cable wires. Network options are also set here.
There are two basic types of cable modem routers: wired and wireless. A wired model requires all computers that need internet access to be physically connected to the device via Ethernet cables. A wireless model can communicate with all computers using radio waves, eliminating the need for cables.
A wired modem router offers the best speeds and the best security, but it has the disadvantage of being limiting and in some cases impractical. You may need to route unsightly cables to different levels of a home or office building. One solution is to run cables inside walls, ceilings or floors, but this can be expensive. It may be best for a business, however, if security is paramount and the speed and bandwidth of Ethernet is a requirement.
A less expensive and much simpler solution is to get a wireless cable modem router. Once configured, the device can be disconnected from all computers and placed in a central location. Internet access and network traffic is transmitted to any computer within range via a wireless network card. The downside here is that radio transmissions provide slower speeds than wired Ethernet, and the network is open to snoopers if unencrypted. Luckily it’s a small thing to set the encryption options in the configuration tables.
When purchasing cable Internet access from a provider, most companies offer the customer the option of renting a cable modem that is pre-configured to work with the service. Read the terms carefully because not all modems have a built-in router. You can add a router later, but if you want the whole shebang up front, check out the fine print. In some cases the wired model is “free” but the wireless model requires a fee.
A preconfigured cable modem router can be a good option because there is little you do after you receive the modem but plug it in and set up the network. On the other hand, if you enjoy setting up your own devices and are comfortable setting up hardware and software, buying your own cable modem router is a good way to go. You can get the model you want and don’t have to worry about returning it. Manufacturers typically list major compatible Internet service companies that will work with their devices. Prices vary but generally cost $35-$75 US dollars.
