Windows 7 Capable Duplicate Network WLAN Card
With circulating of Windows 7 version RC widely through official sources or download through torrent not mean you can feel all the features of the system is operating. This feature does not seem to be good latest collection of wallpapers, Aero Snap or large icons with the taskbar in Windows 7. Microsoft has apparently embed technology into the latest network system Windows 7, but unfortunately due to lack of driver support for the feature at this time can not be used.
The actual technology has been developed since 2002 by a team of researchers is called Microsoft Virtual WiFi or VWiFi, initially called MultiNet, that is a virtualization architecture for the WLAN card (Wireless LAN) adapter that is capable of double / single wireless network card, so that in the virtual machine more than one adapter installed. VWiFi How it works is very similar to how application virtualization such as VMWare and VirtualBox is work in the operating system so that one computer can run multiple operating systems simultaneously. Technique is already widely used and can benefit from the efficiency.
You definitely think about what benefits can be obtained with the presence VWiFi technology for its users, such that you can set the computer connected with more than one wireless network/hotspot (IEEE 802.11) at the same time start with only one WLAN card only, connected with some of the computers in the ad-hoc mode, the computer as an access point ago share an internet connection to other computers on wireless, save the use of network devices, and may be much more interesting things with the different scenarios that can be used with the existence of this technology. However, there is also loss, is possible if more than one connected network to make the necessary effort will be more, and if you use the laptop that relies on the battery, the battery will quickly Low, more and more connected to the network will also affect performance and cause latency on the performance of the network card.
Windows 7 is the last RC version has VWiFi this feature, but as already mentioned above there is no wireless network card vendor that provides a special driver to be able to utilize, and later will get a special certification from Microsoft in the form of a logo. Unfortunately, the implementation of the Virtual WiFi in Windows 7 will be limited only to create a virtual adapter. May see the negative impact on performance WLAN card if too many are connected to a network that is different.
