How to share PC Internet over Wireless Router on Windows?

I have finally come up with the solution. It's simple really, as simple as anything! Internet Connection Sharing is the way to go. This is what I tried earlier, but it didn't work before due to some errors in the Router configuration.

• 4G Modem once connected will be shown in Network Connections as an Ethernet Adapter.
• The WAN port of the Router should be connected to the LAN port of the Computer.

1. Right click on the Adapter that is connected to the internet.
2. Select Properties.
3. Switch to the Sharing tab and check Allow other network users to connect through this computer's internet connection
4. Its important to make sure that the router is configured to "Obtain IP Address automatically." This can usually be done by connecting the router to a PC via a LAN port and using the web browser. The details should be in the routers manual.

Was trying to do the same thing. I have a Wifi adapter on my PC that connected to my buildings wifi. I needed to connect a printer to a router so I could print from my devices. This is how I did it.

1. Set the router WAN to DCHP.
2. Plugged the Router WAN port into my PC's Ethernet port.
3. In the "Network Connects" settings I made sure that the "Share" was UNCHECKED for the wireless connection.
4. Selected the Unknown connection (Ethernet Adapter) and while holding down the Ctrl key single clicked on the Wireless adapter (highlighting both).
5. Right clicked one of them (doesn't matter which one) and selected "Create Bridge".

That was it. Works great.
