It's difficult to help when you omit so many important details... like......
1: Used in a desktop or laptop pc?
2: Motherboard/computer brand and model?
3: Is the computer custom made or factory made?
Conexant doesn't make PCI modem cards, they make chipsets so the correct interface is "integrated on the motherboard".
And the correct chipset number is CX11252-11.
You need to take time out of your busy schedule to read our
Beginners Guide and
FAQ's posted at the bottom this page... then learn what the purpose of the
HOME and
SEARCH buttons are for at the top of each thread. And last, please realize that a forum is for
READING too, not just for
"Blind Posting".
