 	Assuming you have 4965 chipset,
 
 yes, I do:
 
 iwn0 at pci0:3:0:0:        class=0x028000 card=0x11108086 chip=0x42308086 rev=0x61 hdr=0x00
     vendor     = 'Intel Corporation'
     device     = 'PRO/Wireless 4965 AG or AGN [Kedron] Network Connection'
     class      = network
 
 iwn0: <Intel Wireless WiFi Link 4965> mem 0xdf2fe000-0xdf2fffff irq 17 at device 0.0 on pci3
 
 and I have:
 
 device          iwn             # Intel 4965/1000/5000/6000 wireless NICs.
 device iwn4965fw
 
 in the kernel config.
 
 	this seems to be some weird firmware
 	error. I see many users (including linux) reporting similar issues but
 	could not find any definitive solution.
 
 	At most you can try getting the latest firmware for your chipset and try it out.
 	Probably from http://wireless.kernel.org/en/users/Drivers/iwlegacy

 According to your link, this is the latest version.
 However, there is a question mark (?) against it.
 I don't know what it means, perhaps that they are
 not sure if it works correctly.
 I wonder if an earlier  version should be used instead?
 
 Thanks
