Recoomend me a Win 7 compatible USB Wi-fi access point thing

I can't be strawberry floated changing my wireless security from WPA to WEP every time I want to play DS games online, so I'll be needing one of these. Already have the official Nintendo dongle, but it isn't compatible with Windows 7 and Nintendo have stopped supporting it with software updates. Needs to work with Windows 7 64-bit.

Anyone know of any?
