Intel wifi 5350AGN not cooperating

Hey all,

I recently upgraded the wireless card in my laptop to the intel wifi 5350.  From what I can tell, I received an engineering sample (it was from ebay after all).  Unfortunately, the iwlagn module refuses to load under arch64.  I made sure the firmware was installed correctly, however I get an error whenever I try to load the driver (dmesg):

iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27ks
iwlagn: Copyright(c) 2003-2009 Intel Corporation
iwlagn 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
iwlagn 0000:03:00.0: setting latency timer to 64
iwlagn 0000:03:00.0: Detected Intel Wireless WiFi Link 5350AGN REV=0x24
iwlagn 0000:03:00.0: Unsupported EEPROM VER=0x21b < 0x21e CALIB=0x4 < 0x4
iwlagn 0000:03:00.0: PCI INT A disabled

To make sure that the card wasnt at fault, I booted into an ubuntu live cd... which supported the card just fine and immediately found a connection.  According to dmesg, ubuntu (which uses the 2.6.28 kernel) has the same version of the iwlagn module as arch64 currently has (which uses kernel 2.6.30).  I thought that maybe, because I was using an engineering sample that I'd need an older firmware, so I copied the firmware from ubuntu and dropped it in my arch system... unfortunately that changed nothing.

So I have run out of ideas as to how to fix this.  If anyone has any ideas, I would greatly appreciate it!

Hi

Just a suggestion... Have you checked this link?

Yup, that was the first thing I checked... The only help it really provided was specifying the firmware I needed... but this problem seems to be unrelated to the firmware. 

Is there perhaps a particular kernel flag that I need to enable? Or is there a way to force iwlagn to skip version checking?

Re: Intel wifi 5350AGN not cooperating

let me guess, you got your card from ebay like i did? i think it may be an "engineering sample"

i'm having the exact same problem, i've been looking into it for a little while now (works on kernel 2.6.28, nothing above that, iwlagn gives me the exact same error) to compound this problem for me i'm brand new to arch!

check this bug filing out: http://bugzilla.intellinuxwireless.org/ … gi?id=1991

hate to say it, but the problem looks rather grim, the firmware on the card appears to be older than is supported, and intel don't provide any tools or updated firmware. commenting out the eeprom check appears to not work and result in errors.

Yeah, it didnt look too positive... Why does it work in 2.6.28, it doesnt make sense!  After all, the version of iwlagn is the same in 2.6.28 and 2.6.30.  Perhaps there is a particular kernel flag that is needed, and thus a custom-compiled kernel might fix the problem?

Gah, I knew it was a stretch to begin with... Right now I am stuck using ubuntu/mint until my initial wireless card is supported without ndiswrapper... ugh total arch-withdraw!

Re: Intel wifi 5350AGN not cooperating

what i would like to know is does the "fixed" status on the bug mean it's fixed? or is going to be totally ignored :S otherwise looks like i need a new wifi card.
