iwn

I seem to recall I added this in a desperate attempt to get my WiFi working according to iwn()
Code:
if_iwn_load="YES"
iwn4965fw_load="YES"

Do I really need this?
 
Yes, you need to load the firmware specific for your card.

Code:
     Alternatively, to load the driver as a module at boot time, place the
     following lines in loader.conf(5):

           if_iwn_load="YES"
           iwn1000fw_load="YES"
           iwn100fw_load="YES"
           iwn105fw_load="YES"
           iwn135fw_load="YES"
           iwn2000fw_load="YES"
           iwn2030fw_load="YES"
           iwn4965fw_load="YES"
           iwn5000fw_load="YES"
           iwn5150fw_load="YES"
           iwn6000fw_load="YES"
           iwn6000g2afw_load="YES"
           iwn6000g2bfw_load="YES"
           iwn6050fw_load="YES"
This loads a bunch of different firmwares, you really only need the one specific for your card.
 
I have a number of FreeBSD installations, and I'm not sure what iwn4965, which is only installed on one gives me.

On one installation I'm currently using, I notice that I get a message

Code:
iwn0:  iwn_read_firmware: ucode rev=0xe43d0210

I am able to ping 8.8.8.8 so am not sure what I might be missing not having the driver loaded.
