How to: Crte Wireless Hosted Networks in 7

What is a wireless Hosted Network?


Though the VirtualWiFi project disbanded before the fture was fully implemented, has included some of the underlying functionality in 7 and Server 2008 R2. coined the name, wireless Hosted Network, for this new fture.

The wireless Hosted Network fture uses the VirtualWiFi technology along with a software-based access point (AP) fture. Thus, it lets anyone with a supported Wi-Fi adapter and driver to become a wireless AP for other Wi-Fi users, while also having the ability to connect to another wireless network. It also includes a DHCP server, so users automatically receive an IP address.
One use of this new fture might be to extend a hotel’s paid-Internet connection to other Wi-Fi users for free—not that I advoe this practice. Another more legitimate use might be to “rept” a network’s signal. In any case, it serves as a quick mobile AP.
Others might suggest that you can use this virtual AP as a Wi-Fi hotspot. Just remember, even though the wireless Hosted Network is encrypted, giving out the comprises the security. People with the can snoop on the other users that are connected. Plus the users might give the to others.
End-users can interact with the wireless Hosted Network via the netsh command-line tool. Software developers can also write front-end utilities, like Connectify, or use the capabilities in other third-party appliions. In this article, we are going to experiment with the netsh tool.
Getting started with wireless Hosted Networks

In order to use the wireless Hosted Network fture, your wireless adapter must be using drivers certified for 7. If detects a supported adapter, it will automatically add a connection to the Network Connections window, named Virtual WiFi Miniport Adapter, such as Figure 1 shows. If multiple supported-adapters exist, will automatically choose the one to use for the wireless Hosted Network.



requires all wireless Hosted Networks to use WPA2-PSK (AES) encryption. However, there is not a mechanism put in place to prevent file sharing. Hosts and clients should manually protect shares if not all users can be trusted.
In addition, keep in mind that wireless Hosted Networks do not automatically restart after the computer resumes from sleep, hibernate, or restarts. However, if used, a third-party utility might initiate a reconnection. If you manually start the wireless Hosted Network again, will use the previously entered network details though.
Manually crte a virtual AP with netsh
If you want to experiment with the wireless Hosted Network fture with text commands, click the Start button, enter “cmd” and hit Enter. Once the Command Prompt window apprs, you can enter the following to set the network details:

netsh wlan set hostednetwork mode=allow ssid=YourVirtualNetworkName =YourNetwork
Of course, replace the SSID and placeholders with your desired network name and WPA2-PSK encryption .
Before you enable the Hosted Network, you can configure the rl network adapter to share its Internet access using the Internet Connection Sharing (ICS) fture of . This way people connecting to the virtual AP will receive Internet access. You can lve the Command Prompt open so you can start the Hosted Network later.
To enable ICS, navigate through the Control Panel or Network and Sharing Center to bring up the Network Connections window. Then right-click the network adapter that’s connected to the Internet and select Properties. Then select the Sharing tab, check the Allow other network users to connect through this computer’s Internet connection, choose the Hosted Network Connection from the drop-down listbox, and click OK. See Figure 2 for an example.
Figure 2.
Now return to the Command Prompt and enter the following to enable the Hosted Network:
netsh wlan start hostednetwork
To manually turn the Hosted Network off, enter the following:
netsh wlan stop hostednetwork
To see the Hosted Network details (see Figure 3), including the MAC addresses of connected users, enter the following:
netsh wlan show hostednetwork
To change the WPA2-PSK , you can enter the following:
netsh wlan refresh hostednetwork YourNewNetwork



It’s a virtual APNow others nrby should see the Hosted Network appr in their list of available wireless networks. They can connect like normal and enter the encryption when prompted.
Remember, you’ll have to manually start the Hosted Network again, if desired, after rebooting the computer. Most importantly, remember sharing isn’t blocked; make sure you only invite people you trust.
