iwconfig have no results since 2.6.24 kernel update with intel 3945

Hello,

Since the last update of the kernel (2.6.24) in x86 with an intel 3945ABG wireless chipset,
I have no wireless extention in iwconfig.
I have just l0 and eth0 (ethernet).

what I supposed to do to have my wireless come back ?
Is it a module to load at boot or something else ?

Thanks

Re: iwconfig have no results since 2.6.24 kernel update with intel 3945

I presume that you're using the ipw3945 or iwlwifi drivers? If so, when you updated the system, the correct newest version should have been pulled in along with the kernel update. (Mine gave me a newer ipw3945 and catalyst drivers, for example).

Try 'pacman -S ipw3945 ipw3945d' or 'pacman -S iwlwifi' and see if it gives you your updated driver/modules.

If you are using the non-standard 'vanilla' 'tp_plus' 'rt' or 'dkms' kernels, there might also be newer drivers floating around, otherwise it's up to you to compile them...

Edit: Actually, according to this post the iwlwifi drivers are included in the kernel, so if you saw something like this:

:: Starting full system upgrade...
:: Replace iwlwifi with core/kernel26? [Y/n]

And answered 'Y' then you already have them. A simple matter of 'modprobe iwl3945' should bring your interface back.

Thanks for your response wyvern.

That the problem, I replace iwlwifi with the new kernel26 but I don't have module iwl3945.
I tried modprobe -l | grep iwl3945 and there are no results !!!

I use the official Arch kernel.

Is there anything in dmesg about loading the module?

Thats work !!!
I reinstall  iwlwifi-3945-ucode, reinstall kernel26 and restart and that work.

for information installing  iwlwifi-3945-ucode and rebooting was not enough for me I had
to reinstall kernel26 !
