what speed does the card take? a b g bg abg?
You probably have bought the card and from somewhere and on the box or card should be a name/number
posted that and the vendor
you also can try to run
cardctl ident "Socketnumber"
or
cardctl info "Socketnumber"
that should give you some info, I can't give you the data of mine as a friend has my card at the moment.
Is it a Proxim you have? then look
here
almost all are available in Gold and Silver
