Hmm okay things are starting to make sense. A NIC can be either wired or wireless. In this case the "012938/d" is in fact a PCMCIA card only for a notebook like the one below.

Okay, that orinoco silver PCMCIA card is entirely separate from the Ipaq so we'll leave that part out since it will not affect the function of the networking capabilities of the Ipaq.
Is the network card that you speak of on the Ipaq a wired or wireless card and does that have a model number? It is an expansion card correct?
