Configuring windows 7 to provide secure wireless access point services to wi fi

  1. 1. Configuring Windows 7 To Provide Secure Wireless Access Point Services to Wi-Fi Clients - Turn Windows into an Access Point PREPARED BY RAVI KUMAR LANKE Page 1
  2. 2. Not many people are aware that Windows 7 has built-in capabilities that allow it to be transformed into a perfectly working access point so that wireless clients such as laptops, smartphones and others can connect to the local network or obtain Internet access. Turning a Windows 7 system into an access point is an extremely useful feature, especially when there is the need to connect other wireless devices to the Internet with no access point available. When Windows 7 is configured to provide access point services, the operating system is fully functional and all system resources continue to be available to the user working on the system. In addition, the wireless network is encrypted using the WPA2 encryption algorithm Even though there are 3rd-party applications that will provide similar functionality, we believe this built-in feature is easy to configure and works well enough to make users think twice before purchasing such applications.

  3. 3. Creating Your Windows 7 Access Point While there is no graphical interface that will allow you magically to turn Windows 7 into an access point, the configuration is performed via CLI using one single command. We should note that when turning a Windows 7 station into a Wi-Fi access point, it is necessary to ensure the station’s wired network card (RJ45) is connected to the local network (LAN) and has Internet access. Wireless clients that connect to the Windows 7 AP will obtain Internet access via the workstation’s wired LAN connection and will be located on a different subnet network. To begin, click on the Start button and enter cmd.exe in the Search Programs and Files area as shown below: PREPARED BY RAVI KUMAR LANKE Page 3
  4. 4. Next, right click on cmd.exe and select Run as administrator from the menu. This will open a DOS prompt with administrator privileges, necessary to execute the CLI command. As mentioned earlier, a single command is required to create the Windows 7 access point and here it is: netsh wlan set hostednetwork mode=allow ssid=”myssid" key=”mykey” keyUsage=persistent The only parameters that will need to change from the above command are the ssid and key parameters. All the rest can be left as is. The ssid parameter configures the ssid that will be broadcast by the Windows 7 operating system, while the key parameter defines the WPA2-Personal key (password) that the clients need to enter in order to connect to the Wi-Fi network.

  5. 5. Following is an example that creates a wireless network named Firewall.cx with a WPA2 password of $connect$here : C:Windowssystem32> netsh wlan set hostednetwork mode=allow "ssid=Firewall.cx" "key=$connect$here" keyUsage=persistent The hosted network mode has been set to allow. The SSID of the hosted network has been successfully changed. The user key passphrase of the hosted network has been successfully changed. C:Windowssystem32> PREPARED BY RAVI KUMAR LANKE Page 5
  6. 6. When executed, the above command creates the required Microsoft Virtual WiFi Miniport adapter and will setup the hostednetwork. The new Microsoft Virtual WiFi Miniport adapter will be visible in the Network Connections panel as shown below. In our example the adaptor is named Wireless Network Connection 2. Note that this is a one-time process and users will not need to create the adaptor again: PREPARED BY RAVI KUMAR LANKE Page 6
  7. 7. Next step is to start the hosted wireless network. The command to start/stop the hostednetwork is netsh wlan start|stop hostednetwork and needs to be run as administrator. Simply run the command in the same DOS prompt previously used: Notice how our Wireless Network Connection 2 has changed status and is now showing our configured SSID Firewall.cx: PREPARED BY RAVI KUMAR LANKE Page 7
