I had been using Virtual Router manager for the last 2 months and it worked just fine. I use the D-Link DWA-510 adaptor. It is compatible with Windows 7 and there is a "Microsoft Virtual Wifi miniport" in the devices list.
But this morning, it suddenly stopped working, and I had a "Virtual Routeur Could Not Be Started" message :/
In between, I had been toying a lot with open vpns, so my computer is the host of many virtual networks, but... I haven't touched Virtual Router !!!
I uninstalled and re installed, but it just doesn't want to work :/
Thank you for your help :)
