Hi Andrew,
Saturday so...Gone fishing!
Have you gone to the Inventel web site? If you register there you can
download the latest drivers for your model and see if that makes a
difference. Also, try going to Add/Remove Hardware and see if you can
install it from there as a network adapter, instead of using the Welcome
Screen app. I have never used this particular NIC so I can't be
of as helpful as I would wish to be. Also, were you running that card and
modem on the same computer that you are installing Vista on?
Best Regards,
Connie
