There are two ways to share a single Internet connection among several computers within a network, that is:
This article discusses some common problems encountered while enabling and/or using Internet Connection Sharing in Windows 7, and their corresponding troubleshooting procedures. Internet Connection Sharing (ICS) is a built-in feature in Windows that enables multiple computers to share one Internet connection from a single computer (called host). This local area network setup consists of a modem connected to the host computer, and then the client computers connected to the host computer either thru wired or wireless connection. Below is a sample diagram on how ICS is setup in a Local Area Network (LAN):
Click the option below that matches the ICS problem you are currently experiencing:
If you are receiving this error message while trying to share your Internet connection on a Windows 7 computer, follow the steps below:

If this is the scenario you are currently experiencing on your network, try setting up a network bridge on the host computer as an alternative option. Creating a network bridge in Windows is a method that allows a computer to communicate and share its connection with other computers connected to it, whether wired or wireless in nature. For instructions on how to set up a network bridge in Windows 7, perform the steps below:
STEP 1: Right-click the network icon (computer icon) located on lower-right hand corner of your taskbar then select Open Network and Sharing Center.
STEP 2: Click on the Change adapter settings link.
STEP 3: Hold down the [CTRL] key then select the two networks that you want to bridge.
NOTE: When creating a bridge connection, there must be at least two networks to be connected (normally one Local Area Connection and one Wireless Network Connection).
STEP 4: Right-click on one of the networks that you want to bridge then select Bridge Connections.
NOTE: Click Yes when prompted by the User Account Control (UAC) authorization window.
STEP 5: Once the Network Bridge icon appears and indicates that it is connected, check if the client computer can now access the Internet.
