Summary: This post is a response to a request by a friend on how to use his modem on more than one computer. Here’s how…

Internet Connection Sharing

Some of us have more than one computer at home, but only one modem for browsing. With Internet Connection Sharing, we can easily plug in our modem, connect to the internet on the computer with the modem (let’s call this the Parent computer) and then connect to the internet shared internet connection with the other computer (let’s call this one the Child computer).

This applies to Windows Vista, Windows 7 and Windows 8.

Required: At least two PCs with wireless capabilities.


A:   Set up the Parent Wireless Network

  • Turn on the wireless switch on the parent computer.
  • Right click on the wireless connection icon on the right of your taskbar and click on Network and Sharing Center
  • Click “Set up a new connection or network”

You could also save the network if you plan to use it continually in the future. A dialog box displays for you to choose a connection option.

  • Select “Set up a wireless ad-hoc (computer-to-computer) network”. Click OK. Click Next to proceed to the next screen

  •  Give your network a name and choose your security options (Choose a strong password/passphrase).

B:   Bond your dial-up connection to your wireless connection.

  • Go to Network and Sharing Center. Then click on “Adapter Settings” at the left pane. This brings up a list of your adapters.

  • Right click the modem connection you want to share (in my case, it is Bhati) and click on Properties. This brings up a Properties dialog box.
  • Click on the “Sharing” tab (to the extreme right), and click on the check box “Allow other network users to connect through this computer’s internet connection”. Click OK on any User Account Control dialog box if it appears.
  • Select the Home networking connection you want to share this dialup connection with. In our case, it’s the wireless connection.

For security, uncheck the “Allow other network users to control or disable the shared internet connection”

Extra tip: If you click on settings, you are rewarded with the extra option of enabling interesting services (like FTP, IMAP, SMTP, POP, Telnet, Web Services and more) but that’s much more advanced, so I’ll stick with the basics of getting what we want right now.

  • Click OK. ICS is now enabled for your wireless connection.

Note: When you created the wireless connection (mine was called ECHONet remember?), there was a slight change when we click the network icon on the taskbar. ECHONet is now “Waiting for users”

All you need to do now is

  • Connect your modem and turn on the connection
  • Turn on the wireless switch on your parent computer (if it’s not already on) and Connect to your wireless network (if you’ve not already connected it)
  • Turn on the wireless switch on your child computer. After a while, it discovers the wireless network.
  • Connect to the wireless network and provide the security key you created earlier.

Finally, after a few seconds, you can begin browsing.
