Another one:
root at tarzan:~# find /lib/firmware -name "iwl*"
/lib/firmware/iwlwifi-1000-3.ucode
/lib/firmware/iwlwifi-3945-2.ucode
/lib/firmware/iwlwifi-5150-2.ucode
/lib/firmware/iwlwifi-4965-2.ucode
/lib/firmware/iwlwifi-6050-5.ucode
/lib/firmware/iwlwifi-6000-4.ucode
/lib/firmware/iwlwifi-5000-5.ucode
/lib/firmware/iwlwifi-100-5.ucode

/lib/firmware/iwlwifi-5000-1.ucode
/lib/firmware/iwlwifi-6050-4.ucode
/lib/firmware/iwlwifi-6000g2a-5.ucode

(The above find command is so that you know if you have the proper
firmware installed)
