Internet Sharing on Mac via Airport to Windows XP (OS X Leopard)

Ever since my Dad bought us an unlimited Sun Broadband wireless, my sister and I sometimes fight over who gets to use the modem for the time-being. I later discovered that it was possible for a Mac(I have a white Macbook, OSX Leopard) to share its Internet Connection via Network Devices.

Ways of Sharing Internet Connection via Airport:

1. Sharing the DHCP connection.

on Mac:

1. Open System Preferences.
2. Click on the “Sharing” icon
3. Click on the “Internet Sharing” item list.
4. On the “Internet Sharing” item list, make sure that there’s a written name(i.e. ruzette) in the Computer Name field, selected source of connection (i.e. HUAWEI Mobile) in the Share your Connection from Combo Box and check the Airport Check Box in the To Computers Using list.
5. On the “Airport Options”, make sure that the “Enable encryption (using WEP)” remains unchecked.
6. Check the “Internet Sharing” check box.

on Windows XP:

1. On your Wireless Connections, Click on the Network name provided on the Mac.
2. Click Connect.
3. If it is not entirely connected (i.e, Limited Connection), go to Command Line Prompt (Start->Run->Type “cmd” -> OK) then type “ipconfig /renew”(It renews all your adapters’ connections). Hit the Enter key.

2. Sharing the WEP connection.

on Mac:

1. Open System Preferences.
2. Click on the “Sharing” icon
3. Click on the “Internet Sharing” item list.
4. On the “Internet Sharing” item list, make sure that there’s a written name(i.e. ruzette) in the Computer Name field, selected source of connection (i.e. HUAWEI Mobile) in the Share your Connection from Combo Box and check the Airport Check Box in the To Computers Using list.
5. On the “Airport Options”, check the “Enable encryption (using WEP)” box. Set the WEP-length to 40-bit.
6. Now this is the fun and vital part. After setting the WEP-length to 40-bit. You can only create hexadecimal passwords, meaning that only numbers from 0-9 and letters from A to F are allowed. Also, make sure that the “$” (dollar sign) is in front of the password (i.e. “$09342ABF”). Click OK. (Any combination using the mentioned numbers and letters is allowed. )
7. Check the “Internet Sharing” check box.

on Windows:

1. On your Wireless Connections, Click on the Network name provided on the Mac.
2. Click Connect.
3. If it is not entirely connected (i.e, Limited Connection), Right click on the “Wireless Connection” icon, Click on Properties.
4. On the Properties window, click on the “Wireless Networks” tab. Select the Network name on the Mac then select the “Configure” button. Check the “Data encryption (WEP enabled)” and the “Network Authentication (Shared mode)” boxes. Enter the network key we provided on the Mac except that we remove the dollar sign(“$”) in front of the key.
5. Make sure that the “Enable IEEE 802.x authentication for this network” remains unchecked in the Authentication tab.
6. Click OK.
7. Restart your connection if it still does not work.

The procedures on Windows XP can also be applicable on Windows Vista.
