Virtual WiFi helps a user connect to multiple IEEE 802.11 networks with one WiFi card. VIt works by exposing multiple virtual adapters, one for each wireless network to which connectivity is desired. Virtual WiFi uses a network hopping scheme to switch the wireless card across the desired wireless networks.
My Microsoft Virtual Miniport Adapter is not up to date (It tells me this when I try to connect wirelessly to something and also when I view it in Device Manager, it has a caution sign next to it.) and when I went to install it in Windows update, it failed several times to install so I gave up. Now I keep going to update the driver in device manager but it keeps saying it is up to date, even though it's not! I uninstalled the driver sofware completely and restarted my PC in hopes that it would install new driver software, but it didn't, it just reinstalled the old driver software and it still says the driver software is old and not functioning properly. By the way I am running WINDOWS 7. I can't even connect to the internet!
