Intel 6050 wireless adapter problems


I have an Asus U52F laptop with the Intel 6050 network adapter.

# lspci | grep WiFi
02:00.0 Network controller: Intel Corporation WiMAX/WiFi Link 6050 Series (rev 5f)
I've downloaded the Intel firmware and dropped it into the correct location according to the README.

# ls -l /lib/firmware | grep iwl
-rw-r--r-- 1 root root 469780 Jul 10 13:18 iwlwifi-6050-5.ucode
I am using the current module from compat-wireless. When I modprobe iwlagn, I get no error message, and the module shows up in lsmod.

# lsmod | grep iwlagn
iwlagn                158054  0 
mac80211              179615  1 iwlagn
cfg80211              139799  2 iwlagn,mac80211
However, no wireless devices show as being attached to my system!

# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.
I also see errors in dmesg.

# dmesg | tail
iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree:
iwlagn: Copyright(c) 2003-2011 Intel Corporation
iwlagn 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
iwlagn 0000:02:00.0: setting latency timer to 64
pci_resource_len = 0x00002000
pci_resource_base = ffffc90016384000
HW Revision ID = 0x5F
pci_enable_msi failed
iwlagn 0000:02:00.0: PCI INT A disabled
iwlagn: probe of 0000:02:00.0 failed with error -1
I've been scratching my head and googling this for over a week now. Any ideas where I am going wrong?

Thanks for your help!

What do you get when you do this?
grep CONFIG_PCI_MSI /boot/config-`uname -r`

Thank you for the reply. I am making progress.

Before I left for work this morning I found the CONFIG_PCI_MSI option in the kernel config and enabled it. Rebuilt the kernel as well as compat-wireless.

After a reboot I was able to load the module, and everything looked fine in dmesg and ifconfig showed a wlan0 device which I never had before. However, iwconfig spits out a bunch of crap and locks up my system. I can try to post some of this output when I get home tonight.

I'll probably try uninstalling compat-wireless and just use the kernel's iwlagn module and see if I get a different result.

Success! Used the kernel's iwlagn module instead of the one from compat-wireless, and iwconfig works correctly now.
