I have a server running Windows 2008 R2 x64 with a total of three network cards: one on-board, one PCI, and one Wireless USB dongle (D-link DWA-140). The on-board card is connected to the internet, the PCI one is connected to my cabled home network and currently the USB dongle isn't connected to anything.
What I'm trying to do is to enable DHCP on the USB dongle so I can connect to my server through wireless devices and connect to the internet through it.
I have tried a third-party program called Virtual Router, which successfully turned the USB dongle into a DHCP-enabled hotspot, but it did this by stealing the connection of the PCI-card so I would basically have to choose if I wanted to connect to the internet through the cabled net or wireless only.
I have also tried this solution to share an internet connection on multiple networks but I couldn't get it to work (just like the original poster), and since it required disabling ICS I couldn't even try Virtual Router when this was set up. I did manage to get internet connection through the cabled network though.
Can anyone help me? I never imagined it would be this hard to share an internet connection on multiple nets with windows, I did it just fine with cabled cards using FreeBSD once upon a time.
