How to Run a Modem and a Wireless Router Together

Not everyone has broadband Internet service. Thus, there are times when you'll need to be able to connect to a home WiFi network in order to access other computers in the home (for file sharing and printer sharing) but still connect to a dial-up Internet provider. To accomplish this, it will be necessary to run a modem and a wireless router together.

Difficulty: Moderate

Instructions

Things You'll Need:

• Wireless router
• Personal computer
• Modem

Run a Modem and a Wireless Router Together Using a Windows Operating System

1. Look for a router that supports dial-up modems. If you're purchasing a wireless router, you can look for this feature, but as dial-up modems and ISPs are increasingly replaced with broadband DSL or cable, these routers are becoming less common.

2. Set up a desktop computer with a modem and network. This computer, in addition to the wireless router, will itself act as a router. It should have the modem connection and either a wired network connection that goes to the WiFi router or a WiFi connection itself.

3. Set up Internet Connection Sharing, effectively turning the desktop computer into a router.

4. Set up one of a number of firewall choices to protect your computer from worms or other remote attacks. Windows XP comes with a firewall, but there are also a number of commercial and free firewall products you can get over the Internet. While Internet Connection Sharing will work without this firewall, be aware that your computer will be at risk.

5. Click on "Start -> Control Panel -> Network Connections."

6. Right-click on the dial-up connection (or another connection to the Internet) and select "Properties."

7. Click on the "Advanced" tab.

8. Choose "Allow Other Network Users to Connect Through This Computer's Internet Connection," in the "Internet Connection Sharing" section.

9. Select "Establish a Dial-Up Connection Whenever a Computer on the Network Attempts to Access the Internet."

10. Hit the "OK" button.

11. Configure the wireless router to run in bridging mode. While in bridging mode, the wireless router only bridges the wireless and wired connections, and does not act as a router. The technique varies depending on your router manufacturer and model, so refer to your manual before completing the process.

Tips & Warnings

• Be aware that the computer acting as a router will be directly connected to the Internet and will be vulnerable to worms and other remote attacks. This is usually not the case when connecting through a home broadband or wireless router, so be aware that you should take extra steps for protection when running a router and modem together.
