How to Connect a Wireless Router to a Time Warner Cable Modem

By Dean Lee

The downside to many DSL or cable modem connections, such as a Time Warner cable modem, is that only one user can connect to the Internet at one time. However, if you add a wireless router, you can increase the number of users who can connect either wirelessly or through a wired connection. For a wireless connection, you need to configure both the wireless router and the computers using that connection with the same network name (called the SSID) and the wireless security key. The procedure for connecting and configuring a wireless router is generally the same regardless of what DSL or cable modem you use.

Things You'll Need

  • Time Warner cable modem
  • Coaxial cable
  • Ethernet cable
  • Wireless router
  • Computer

Step 1

Connect the Ethernet cable from one of the LAN ports on the back of the wireless router to the computer.

Step 2

Open a web browser and type in the address for the router utility. The address looks similar to "192.168.X.X." Refer to the router's user manual for the specific address. If you are required to log in, the default username and password commonly are "admin" and "password," respectively. Refer to the router's user manual for specific login information.

Step 3

Navigate to the router's wireless settings, most likely named "Wireless" or "Wireless Settings."

Step 4

Enter the SSID for your network in the specified box under the Wireless settings. If you can enter the wireless security information here as well, select the Wireless security type you wish to use, then enter the security key. The router utility will give you parameters you need to follow for creating a wireless security key. If the security information is not under the same tab, click on "Security" under the wireless settings, then enter the wireless security information there.

Step 5

Save the settings, then exit the router utility.

Step 6

Disconnect the Ethernet cable from the computer and the LAN port on the router and reconnect it to the WAN port on the back of the router and to the Internet port on the Time Warner Cable Modem. Turn on both the modem and the router.

Step 7

Open your computer's wireless utility. Double-click on the icon for the wireless utility in the system tray at the bottom right corner of your desktop. The icon looks like a computer with a signal coming out of it, though it could also look like a series of increasing bars depending on your computer. Refer to the computer's user guide for the specific wireless icon for your computer.

Step 8

Double-click on SSID that you configured for your wireless network, then enter the security key when prompted. Click on "Connect" or "OK" to connect to the Internet wirelessly.
