Windows 7 Ad Hoc Network: Share Internet Connection Wirelessly
Creating a Wireless Ad Hoc Network in Windows 7
There are instances when a Wi-Fi connection isn't accessible for your portable devices, or when file sharing between wireless computers becomes necessary. This guide details how to establish a wireless ad hoc network in Windows 7 to address these situations.
An ad hoc network represents a localized area network that can be rapidly constructed when needed. It facilitates direct communication between computers and devices within a limited range. The capability to form such a network has been available since Windows XP, offering a swift method for data exchange and Internet connection sharing with other wireless devices. For this process, the host computer should be connected via an Ethernet cable and possess wireless functionality, like a laptop or netbook.
Setting Up the Ad Hoc Network
Begin by opening the Start Menu and entering "wireless" into the search field. Select "Manage wireless networks" from the results.
To initiate network creation, click the "Add" button.
Next, choose "Create an ad hoc network…
A message explaining the nature of an ad hoc network will appear; click "Next" to proceed.
Network Configuration
Assign a name to your network and configure the security settings. Selecting "Save this network" is recommended if you anticipate frequent use, avoiding repeated setup. The available security type is dependent on your wireless adapter’s capabilities. For quick connections with diverse devices, disabling security can be simpler. However, for continuous use, enabling security is strongly advised.
Allow time for the network to be created…
The network creation was successful and is now ready for use.
Connecting Client Devices
Confirm the network’s status by clicking the wireless icon in the Taskbar. You’ll see that it is awaiting connections from users.
On the client computer, select the wireless icon to view available networks and connect to the newly created ad hoc network.
The host machine will then display the connected client computer.
Sharing Internet Connection and Files
File sharing between the connected machines is now possible. To share the Internet connection, right-click the host’s wireless adapter icon. Navigate to Properties, select the Sharing tab, and enable "Allow other network users to connect through this computer’s Internet connection."
Within Settings, you can specify the network services accessible to the client machine.
Documents and the Internet connection can now be shared between devices. This example demonstrates connectivity between a Windows 7 desktop with a wireless card and a netbook running Windows 7 Home Premium.
An XP machine can also be connected. Here, an XP laptop is connecting to the ad hoc network.
Creating an ad hoc network provides a convenient solution for quickly sharing your internet connection, particularly in situations like meetings or hotels lacking Wi-Fi. Remember that devices should remain within approximately 30 feet of the host computer, and the connection speed may be reduced, especially with multiple connected devices.
