A wireless router is the device used most often to broadcast Wi-Fi signals to wireless-ready devices within range. However, not all networks are wireless, and routers sometimes die without warning. Windows 7 includes a feature called Internet connection sharing that allows one or more wireless-capable devices to connect wirelessly to the Internet using a computer linked via an Ethernet cable to a wired network. You can set up an ad-hoc, or point-to-point, network on a PC and enable ICS to turn the computer into a wireless hotspot.

Step 1

Connect the PC to the router via an Ethernet cord. Click "Start" and then type "sharing" in the search box. Click "Network and Sharing Center."

Step 2

Click "Set Up a New Connection or Network" under Change Your Networking Settings.

Step 3

Select "Set Up a Wireless Ad Hoc (Computer-to-Computer) Network" from the Choose a Connection Option screen. Click "Next."

Step 4

Review the information on the screen and click "Next." Create a name for the hotspot and choose "WPA2-Personal" from Security Type.

Step 5

Create a password for the network. Click "Save This Network" to use it in the future. Click "Next" to establish the network. Click "Close."

Step 6

Choose "Manage Network Connections" in the left pane. Right-click the ad-hoc network and select "Properties" from the context menu.

Step 7

Click "Sharing" and then select "Allow Other Network Users to Connect Through This Computer's Internet Connection." Click "OK" to begin using the PC as a wireless hotspot.
