I've just bought a logilink firewire 2 port card bus for my Acer Aspire 9420
laptop to download recordings from my videocam. The packaging states that it
works with Vista. When I insert the card I lose my wireless internet
connection (the router simply disappears from the wireless menu) and have to
take the card out and reboot the laptop to get it back . Internet connection
aside, Movie Maker cant find the card and videocam. The card doesnt appear
on 'my computer'. However in device manager both the host controller and
card show as working. The former has the latest driver update, the latter
doesnt require a driver as it runs off the operating system.

Acer couldnt help. Logilink just suggest I try and get my money back (which
I cant as the product isnt faulty per se).

Any advice would be much appreciated as I seem to have come to a dead end.
