In Windows, when you enable the WiFi connectivity, the PC keeps scanning for available WiFi networks. You can click on the small WiFi icon in the notification area to find the list of all the available WiFi access points and you can choose any one of them to connect after supplying the proper authentication. But once the connection has taken place, there is no real use of the operating system continually scanning for the available networks. Scanning for the available networks consumes a little WiFi bandwidth and interferes with the internet connection bandwidth available for your use.
Usually this does not matter much, but if you want to make full and complete use of all the available WiFi network bandwidth to access the internet connection, you would want to disable or stop Windows from continually scanning for the wireless networks. This can be done easily by disabling or stopping the Windows service labeled “WLAN AutoConfig”. You can do this through the services manager or by using the free WiSwitch application.
The WiSwitch makes enabling, disabling, starting and stopping the WLAN AutoConfig very easy through its small window. After launching WiSwitch, you can view the status of the WLAN AutoConfig service whether it is running or not. If you have already connected to a WiFi network successfully, then you can click on the Stop button to stop this service.
If you want to disable this service altogether, then you can click on the Stop/Disable button. Disabling this service is not recommended though because it will stay disabled even after Windows has restarted. And if in the future you want to connect to a different available wireless network, then you can start the service once again and pick one of the wireless networks as usual.
Conclusion: WiSwitch is a handy application to maximize the use of the available bandwidth from your WiFi hardware. It makes it very easy to start, stop and disable the WLAN AutoConfig service.
