Cable Internet connection uses the existing cable TV wires for Internet access. Since its introduction, Cable Internet has steadily become a popular Internet access technology worldwide. To access Cable Internet, you need either a modem or a router. A modem is usually used for a single computer. However, if you have a network of computers, a cable router is required. Cable routers can also connect networks to each other functioning as network gateways, determining the best path for a data packet, protecting against threats and include in-built switches or hubs. There are several cable routers available. Some of these also work with DSL connections. Here’s how you can buy a router to use with cable:

Step 1:
Buy the cable router from your Cable Internet Service Provider (ISP). Most ISPs provide a basic cable router. You may also be able to lease a router from your cable connection provider. Buying from the ISP is recommended as you do not have to worry about compatibility. Availing the cable router from the ISP would also be cheaper.

Step 2:
Alternatively, compare the features and pricing of cable routers online as well as in local stores. However, in such cases you will have to ensure that the cable router is compatible with your Internet connection and your computer (or network of computers). The steps below help to assess compatibility:

Step 3:
Evaluate broadband routers specially designed for Cable Internet. They are generally defined as Ethernet routers. Routers for DSL connections are called broadband routers. However, some Ethernet routers also work with DSL.

Step 4:
Know whether the network of computers is wired or wireless. Cable routers for wired networks cannot be used with wireless networks. If buying a wireless cable router, determine the underlying technology—Bluetooth or Wi-Fi. Make sure that the wireless router you purchase is compatible with your wireless network.

Step 5:
Buy a cable router that provides additional features, if required. For instance, a cable router with numerous ports can also act as a switch and connect to several computers. Other cable routers have built-in firewalls and support port forwarding ability required to host a web server. Cable routers can also be used to connect to a Virtual Private Network (VPN).

Step 6:
Pay attention to power requirement. High power routers can manage a higher workload.

Step 7:
Buy an ergonomic router with easy-to-use buttons. For instance, a clearly visible and easy to operate on/off switch is better than a concealed on/off mechanism.

Step 8:
Research the market for the variety of cable (or Ethernet) routers available, their features, top selling routers and customer feedback.
