No wifi after kernel update

kolezko · October 17, 2010, 8:21pm

Hello,
I’ve installed opensuse 11.3 few days ago on my laptop, and it seems after kernel update, wifi refuses to work. I’m using gnome and after the update the iwlagn module was not present in the ‘ifup’. So i run modprobe iwlagn and here is the output.

box:/home/kolezko # modprobe iwlagn
FATAL: Error inserting iwlagn (/lib/modules/2.6.34.7-0.4-desktop/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko): Unknown symbol in module, or unknown parameter (see dmesg)
sh: /sys/bus/pci/drivers/iwlagn/new_id: Nie ma takiego pliku ani katalogu
FATAL: Error running install command for iwlagn

here’s dmesg

From what I read an option ‘nohwcrypt’ is enabled, whilst the option is not recognized.

rodhuffaker · October 18, 2010, 12:52am

How did you install the driver initially to get it working? Did you manually install or use a repository? Does the kernel version you installed match the module version?

uname -r

rpm -qa |grep iwlagn

rodhuffaker:

uname -r

Well,

/lib/modules/2.6.34.7-0.4-desktop/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko

this is at least the location of the driver already provided with the kernel and no -sane- rpm package containing kernel modules would overwrite that file (but considering what C.R.A.P. you find in OBS, I wouldn’t exclude that possibility).

But Knurpht is most likely on the right track

No parameter called hwcrypt there, but I can make a -more or less- educated guess what might have happened.

Our OP read some “ub0rc00l” tutorial how to use aircrack-ng or related tools -where you often find the advice to disable hardware crypto of your wireless card for better injection etc.- but didn’t really read which options to use for which card and copy&paste is just so much easier than actually reading tutorials.

Now there is some module options file floating around in /etc/modprobe.d/ with parameters the driver just doesn’t know and the kernel update is just the excuse not having to blame the problem on the user himself.
