- 1). Determine how many ports you need by counting all the devices you need to connect. Each device has an Ethernet cable that plugs into a "port" (plug-in) on the router. If you have two printers, a fax machine and another computer, you need a minimum of four ports.
- 2). Determine if you need modem capabilities to connect multiple devices to the Internet. Accessing the Internet requires a modem, and if you have multiple computers, you will need a router-modem that can route the Internet connection to all your computers. If you only want to connect your computer to a printer and other non-Internet-connected devices, you can forget about modem capabilities and just select a router.
- 3). Decide if you need wireless capabilities by double-checking your components for wireless capabilities. Many laptops and printers have wireless ports on them that accept a wireless signal. A wireless router can support an indefinite number of devices, so you don't have to worry about not having enough ports.
- 4). Compare security by checking the router's security specifications in the owner's manual or on the back of the box. Routers employ a firewall that blocks intruders from accessing your computer network. Wireless routers, however, prove less secure, so you need to check for Wi-Fi Protected Access (WPA) or Wi-Fi Protected Access 2 (WPA-2) that allows you to set up a 25-key code users must enter before they can connect.
- 5). Compare prices at sites like tigerdirect.com. Basic routers without modem or wireless features cost $39 to $49. Wireless routers cost $59 to $129. Routers with modem capabilities or with wireless-modem capabilities cost $89 to $199.
- 6). Compare expert reviews by visiting sites like cnet.com, consumerreports.org or consumersearch.com. Some manufacturers, such as 2wire, Linksys or Netgear, have specialized in routers for many years and have established a reputation for quality products, but you should read reviews that rate each product's actual performance.
