How to install driver for ipw3945 wireless card?

[ntrncx]

i am going to install my newest driver of my wireless card ipw3945 and when i use make i get this

ERROR: A compatible subsystem was not found in the following path[s]:

/lib/modules/2.6.21.5 /lib/modules/2.6.21.5/build

You need to install the ieee80211 subsystem from http://ieee80211.sf.net
and point this build to the location where you installed those sources, eg.:

% make IEEE80211_INC=/usr/src/ieee80211/

or use the 'make patch_kernel' within the ieee80211 subsystem to patch your
kernel sources.

i downloaded ieee80211 and after make i recieve this

Checking in /lib/modules/2.6.21.5 for ieee80211 components...
find: /lib/modules/2.6.21.5/build/: No such file or directory
grep: /lib/modules/2.6.21.5/build//.config: No such file or directory
grep: /lib/modules/2.6.21.5/build//include/linux/autoconf.h: No such file or directory
find: /lib/modules/2.6.21.5/build/: No such file or directory
make -C /lib/modules/2.6.21.5/build M=/root/my-documents/ieee80211-1.2.18/ieee80211-1.2.18 modules
make: *** /lib/modules/2.6.21.5/build: No such file or directory. Stop.
make: *** [modules] Error 2

i understood that something missing but how i get it and install it?

Puppy already contains the ipw3945 module, plus firmware.
Is there something wrong with this module?

You need the Puppy 2.17 kernel source, from
http://puptrix.org/sources/kernel-2.6.21.5-pup217/

thanks i downloaded from that folder the big bz2 file i extracted it and followed the instructions from the read me file but i must made a mistake cause it says in order to boot it you must copy the image to the right location but i cant find the image.

i did "make oldconfig' i answer some answers(dont know if i answered corectly)
and after i typed "make"

2)why when i install aircrack i cant run airdump?
