I'm trying to install the mac80211 subsystem in order to install the iwlwifi driver for my wireless card. I have ipw3945 installed. As far as I know I have the kernel sources installed in /usr/src/linux-headers-2.6.18-5-686/ (Nevertheless I know I have them installed due to previous successful installs that have required them). But when using 'make' here is my error output:

Checking kernel compatibility in:
/usr/src/linux-headers-2.6.18-5-686/
grep: /usr/src/linux-headers-2.6.18-5-686/drivers/base/core.c: No such file or directory
! CONFIG_NET_WIRELESS_NETLINK can not be set in .config!
make: *** [compatible/modified] Error 1


I have tried using the development team with little success. I understand what this error message says, but have no idea about anything else.

If I could sneak another question in as well...

Are there any good links or tips for updating my Debian Etch Kernel, I have tried a few HOWTO's, none of which worked for my system. Thanks,
Steven
