If you are someone who has access to multiple wireless connections and wish to connect to multiple wireless connections simultaneously using the only WLAN interface card, this article is a good read for you. Alternatively, you can always go for installing multiple WLAN cards for connecting to multiple wireless networks simultaneously, however, that will be a costly deal and will also drain out quite a lot of battery power of your precious little laptop. Some legacy laptops might not even allow addition of extra WLAN interface card.

VirtualWifi is a free software offered by Microsoft which abstracts a single WLAN card to appear as multiple virtual WLAN cards to the user. The software then allows the user to configure each virtual card to connect to a different wireless network. Therefore in short, VirtualWiFi allows a user to simultaneously connect his machine to multiple wireless networks using just one WLAN card.

Virtual WiFi uses a network hopping scheme to switch the wireless card across the desired wireless networks. Switching between networks is transparent to the applications, such that the user feels she is connected to multiple wireless networks simultaneously.

    In a corporate environment – is this practical?? Aren’t there bandwidth/throughput issues for QOS and 802.11n with having multiple AP’s/wlan’s co-existing in same airspace?

    Where these aren’t a concern, great way to connect to multiple wlans!

    I would be interested to incorporate this in my project.

    Are there any commercial software solution providers for Wifi dual band width monitor and control? If yes, i would like to get connected and buy one.
    There are other solutions like mad wifi for linux however all are R n D concepts.

    Let’s suppose i have 2 neighbors how agreed to share internet with me, letting me use their wifi connection. With this program, could i bond the connections somehow to increase download speed?

  • Faizi5000

    Would it enhance the speed if connect two multiple networks ?

  • dev

    Article clearly says switching is transparent that means still at a single point of time you are connected to only one wifi network
