10.04: Does not recognize wireless usb adapter

[Necis]

Ubuntu 10.04 does not recognize my wireless usb adapter at all. Its a linksys WUSB100 ver.2. How can I solve this?

Did you just upgrade from a previous installation of Ubuntu? If so, did this wireless adapter work under that one?

I don't think a linux-native driver exists for this (I could be wrong, it's happened once or twice before) so your best bet is ndiswrapper:

Good luck.
