Intel 4965agn istalled but not detected.

Zerimas · 2009-10-07 22:56:45

The Atheros card in Asus M50VM was quite terrible so I decided to upgrade to an Intel 4965agn. However, upon installing it Arch didn't detect it, even after I ran modprobe iwl4965. The weird thing is it doesn't show up in Windows either. I don't think I botched the installation, as it is a pretty simple device to install. Does the order that the antennae are plugged in matter? Is it a bum card? Did I somehow fry it when I put it in? I should probably mention that I have the latest version of the module on my system courtesy of the compat-wireless package on the AUR.

Thanks in advance!

Run dmesg after you load the driver, it should tell you something if anything went wrong.

Also:

[stijn@hermes ~]$ lsmod|grep iwl
iwlagn                 70416  0 
iwlcore                81264  1 iwlagn
led_class               1812  2 sdhci,iwlcore
mac80211              125568  2 iwlagn,iwlcore
cfg80211               69360  3 iwlagn,iwlcore,mac80211

I don't know how old your installation medium is, but the iwl4965 driver has been replaced for a while now by the iwl{core,agn} stuff.

After loading the iwlcore module the only line that is added to dmesg is:

CE: hpet increasing min_delta_ns to 33750 nsec

Also the relevant modules appear to be running.

[dan@Syndev ~]$ lsmod|grep iwl
iwlcore               126192  0
mac80211              220288  1 iwlcore
cfg80211              107144  2 iwlcore,mac80211
led_class               5112  3 iwlcore,sdhci,asus_laptop

Why is the card not being detected? Shouldn't udev detect it automatically on boot? I am beginning to think my replacement card is defective, or I botched the install (which I am not sure how I would do, as all I need to do is put it in the slot and plug in the three antennae--unless the order the antennae are plugged in matters).

Edit: after loading iwlagn, the following appears in my dmesg log

Wireless WiFi Link AGN driver for Linux, 1.3.27ks
iwlagn: Copyright(c) 2003-2009 Intel Corporation
iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27ks
iwlagn: Copyright(c) 2003-2009 Intel Corporation

However, no wireless networks are detected and iwconfig shows eth0 and l0 as my only interfaces. lspci also shows no mention of the card.

Iwconfig will only show active interfaces, just like ifconfig. You might have to bring the interface up manually (ifconfig wlan0 up probably).

If lscpi doesn't show anything either the card is broken or you did something wrong during installation...

lspci|grep 4965
03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)

is what it says over here.

P.S. It's lo, not l0 .

I am pretty sure that the card is broken, as I managed to successfully reinstall my old Atheros card. In a strange twist of events, my Atheros card is now performing much better now that I've tried to replace it. Before, I was unable to detect a single wireless network in my room (which is about 10m from my wireless router) now I can seven WLAN networks from the surrounding apartments. I guess I'll just go return it, unless there is something else I should try?

I don't know anything else, besides that if your Atheros card is 802.11g, your system probably wouldn't have enough antennas for the 802.11n card the IPW4965 is. Although I doubt that would stop it from initialising...

Zerimas · 2009-10-08 12:02:33

Actually, my laptop does have enough antennas. My Atheros card (which claims to be an wireless n card) only used two--the third antenna had a plastic insulator around it and was taped down. Looks like a trip to the computer store is in order today.
