Intel Centrino Wireless-N 2200 Tech Support

[Edward Seyler]

I am having difficulty using my Intel Centrino Wireless-N 2200 PCI-E wireless card.  The card is visible but cannot be set "up," either from "ip link" or wpa_supplicant.  I am using Arch Linux but have also observed this problem in Ubuntu 12.04 LTS.  I have downloaded the firmware from http://wireless.kernel.org/en/users/Drivers/iwlwifi and followed the instructions there on how to copy it into /lib/firmware.  Installing Arch Linux's "compat-drivers-patched" package had no effect.  Removing all other PCI/PCI-E devices had no effect.  My wired ethernet connection is fully functional.  Below is the output of several commands that may be relevant, all run as root.  Any assistance would be greatly appreciated.  Please let me know if I can provide any additional information.

Thank you,

Edward Seyler

This is really weird...
Can you compile with CONFIG_IWLWIFI_DEBUG?
I will then need a few debug prints.
I recently changed this flow to speed up the fw loading process on
platform that can afford a bit amount of DMA, but I just tested it
(again) and it works even if there is not big DMA chunk available.

I compiled with CONFIG_IWLWIFI_DEBUG.  I also absent mindedly enabled CONFIG_IWLWIFI_DEBUG_EXPERIMENTAL_UCODE--please let me know if you do not want this.  I can provide other debugging output, but I am sending this now in case I cannot respond promptly.
