Using Intel WiFi with Virtual PC

Specs: Vista Business, 3.5GB Ram
My laptop has an Intel WiFi link 5100 AGN network card that is used (successfully) to connect to wireless APs for Internet access.

On my laptop, I use Virtual PC 2007 to run several virtual machines. For each virtual machine, I have configured the VM to have one network adapter, and have set this adapter to the Intel WiFi Link.

About 85% of the time when I start up any of the virtual machines, the network connection in the VM will have "Limited/No connectivity" due to the fact that it hasn't been able to obtain a IP address. About 25% of the time, repairing the connection from within the VM will correct this. I have also tried going into Virtual PC's network settings (while the VM is running) to disable the network adapter and then reset it to the Intel WiFi link. This procedure fixes the problem about 50%.

This issue happens in all the virtual machines I have (ranging from Windows 98 to Server 2003) when I am using the Intel WiFi link connection. If I change it to my laptop's wired connection, the problem goes away.

Any idea as to why Virtual PC seems to not like using my Intel WiFi Link 5100 AGN connection?

I am kind of confused.

You have a virutal machine. The VM doesn't have a wifi connection it has a software version of a NIC. You simply let the VM manager offer dhcp and dns to the guest OS.

There are three ways you can allow VPC to have networking.

In Virtual PC 2007, the VM settings allow you to select up to four virtual NICs to present to the virtual machine. For each one you can select to map this virtual NIC to a real hardware NIC in the host computer, or set it as "not connected" or "local only". In my case, I choose to present one virtual NIC to the guest machine, and to map this virtual NIC to my real wireless card (in this case an Intel WiFi Link 5100 AGN). This creates the problem described above. If I instead map it to the real hardwired Ethernet adapter in my host OS, the problem doesn't occur. It also doesn't happen if I map it to another wireless adapter in the host OS.
