Internet Connection Sharing Not Working in Windows 10

Internet Connection Sharing Also Known as ICS, is a built-in Windows feature that allows multiple computers to connect to the internet using a single Internet connection on one computer. If you are using multiple computers for your small business then you can use ICS to connect all the computers to the internet. It is very cost-effective. ICS is basically a Windows service that helps you to share the Internet connection from your Primary computer to the other computer via Local Area Connection (LAN). Instead of Switch or Router here your Primary computer act like a Default gateway. All your network traffic transfers over that Primary computer. Basically, ICS uses NAT technologies to achieve this and works with most connection technologies, including DSL, cable, ISDN, dial-up, and satellite. The device with the modem or broadband interface that establishes the connection to the Internet is called the ICS host, or gateway while the other devices that connect to the Internet via the network and the ICS host are called ICS clients. If the ICS host fails, then all of the ICS clients lose their Internet connection. If the ICS Service fails then you can’t share the internet connection. This article will guide you to fix Internet Connection Sharing Not Working in Windows 10.
