How to Set Up a Wireless Router With Time Warner Cable

by Jeff Grundy

In an August 2011 article, PC Magazine listed Time Warner Road Runner as one of fastest Internet service providers in the country. With average download speeds of over 12 megabits per second, a Time Warner cable connection not only lets you surf the Web and stream movies quickly on a single PC, but provides adequate bandwidth for connecting additional computers as well. With a Time Warner cable modem and a wireless router, you can connect multiple desktop and laptop computers to the high-speed Internet connection without cumbersome or unsightly Ethernet cables. You can add wireless support to your network whether you use a Time Warner modem/router combo device or a standalone modem and a separate router.

Connect and Configure Wireless Router

Step 1

Plug one end of an RJ-45 Ethernet cable into the “LAN” port on the back of the Time Warner cable modem, then connect the other end to the “WAN” or "Internet" port on the wireless router.

Step 2

Connect a second RJ-45 Ethernet cable port on the wireless router labeled "Port 1" or "LAN 1" and to the network port on the rear of the desktop or laptop computer. Power on the Time Warner cable modem, Wi-Fi router and the computer -- in that order -- and wait for the computer to boot into Windows. After booting the computer, Windows receives an IP address from the router automatically.

Step 3

Gather your Time Warner account information. Determine the IP address needed to configure your wireless modem by looking for a sticker on the side or rear of the router or referring to the device's user guide. For many wireless routers, the default IP address to access the router configuration page is “” or “” The IP address for your router may differ.

Step 4

Enter the router IP address in the address bar of the browser and press the "Enter" key. Enter the default administrator username and password for the router in the appropriate fields, then press “Enter” or click “Log In.” Again, refer to the label sticker on the router or the user guide to find the default login credentials.

Step 5

Click the "Setup," "Auto Setup," "EZ-Install" or other similarly named menu option on the main page of the router control panel page. Enter your Time Warner account information in the appropriate username and password fields if required. Follow the remaining prompts in the browser window to configure your account and connect the wireless router to the cable Internet connection.

Step 6

Click the "Wi-Fi Setup," "Wireless Network," "Wireless Configuration" or other similar menu option. Enter a descriptive name for your wireless network in the "SSID" or "SSID Name" field.

Step 7

Click the “Security” or “Wireless Security" menu option on the Wi-Fi or Wireless Network configuration page. Select your preferred encryption method for the network. To better protect your wireless network against hackers or those seeking to steal your bandwidth, choose the WPA or [WPA2 encryption](https://itstillworks.com/wpa2-encryption-2469.html) protocol if available or use WEP if the router does not support WPA. Regardless of the protocol you select, choose one with at least 128-bit encryption to make it harder for others to access your wireless network without permission -- 256-bit is even better if the router supports it. Enter a passphrase or security key in the appropriate field or allow the router to generate a random key and then memorize it. Record the key passphrase; you must enter it on other devices you wirelessly connect to the router.

Step 8

Click the "Apply Changes," "Save" or "Save Changes" menu option link or button, then "Reboot" or "Restart." Wait a few seconds for the router to restart and apply the configuration changes for your Time Warner account and the wireless network.

Test the router by opening a Web browser on the computer with the Ethernet connection and opening a few Web pages.

Connect Wireless Devices to the Router

Step 1

Click the wireless signal icon on the right side of the Windows taskbar next to the current date and time display. After you click the icon, a small pop-up window appears and lists wireless networks within range of the wireless network adapter in the computer. Click and highlight the network or SSID name you entered on the wireless configuration page for own router.

Step 2

Click the “Connect” button in the wireless network list window after selecting the network name or SSID of your wireless router. Wait a few seconds until Windows prompts you to enter the passphrase or security key for the wireless network, and then enter the value you entered in the wireless configuration settings or the one that the router generated automatically.

Click “Connect” again and wait for the computer to connect to the wireless router and receive a dynamic IP address. Open your preferred Web browser and test the connection by surfing the Internet as you normally would.


  • If your Time Warner modem has a built-in router, configuring it is essentially the same as with a stand-alone unit. You need only connect the first computer to the "LAN" port on the rear of the modem/router combo device then access its Web control-panel interface to configure the wireless network - just as you would on a regular stand-alone router.
