We will need a better hardware description in order to help you. To my knowledge, there is no network adapter manufacturer named: "02UT21442401"

Give us something to work with... is this a retail boxed product or did it come as part of a pc system?

The only thing I can associate with is "128RC4" belongs to a Proxim Orinoco Turbo 11MB PC Card - Gold pcmcia card. However, these cards were sold by vendors (OEM's like Gateway) as well as retailed boxed products.

If your device came as part of a pc system, then you will probably need to go the vendors website for support. If it came as a retail boxed product, then you should be able to get support from Proxim Orinoco support. However, Proxim Orinoco is one of the most difficult sites I've ever had the displeasure of trying to find something on. It's almost like they don't have any support.

And your post is a bit confusing.... you chose a chipset manufacturer as a member name as well as a manufacturer that just isn't.
