I have an "Intel Wireless WiFi Link 4965AGN Adapter" on my laptop PC. And I've got an ucode package from Intel home site. But I don't know how to use it. I've copied the ucode file to /lib/firmware. But it seems not working for just doing this simply step. Anyone who can tell me the details, step by step. Thanks a lot.

ps. I've erased the ipw3945 driver which was installed by default.
