I wouldn't trust the ORiNOCO combo card. You're better off with one that's strictly 802.11b, like the ORiNOCO Classic cards.
(Sounds like you have a pre-ORiNOCO Classic card and a post-ORiNOCO Classic card. The combo card is made by Proxim, right? The Agere ORiNOCO card is better - that's who makes the ORiNOCO Classic.
)
