problems with installing wifi driver

[vita]

Hello,
I have serious problems with installing driver for my Intel PRO/Wireless 3945ABG wlan card. I have downloaded original linux driver from Intel websites and installed the last ieee80211 package.
Commands:
cd ipw3945-linux-1.2.0/ipw3945-1.2.0 (it's the driver)
sudo make

throw error:

WARNING: Your kernel contains ieee80211 symbol definitions and you
are not using the kernel's default ieee80211 subsystem. (Perhaps you
used the out-of-tree ieee80211 subsystem's 'make install' or have
provided a path to the ieee80211 subsystem via IEEE80211_INC.)

If you wish to use the out-of-tree ieee80211 subsystem then it is
recommended to use that projects' "make patch_kernel" facility
and rebuild your kernel to update the Module symbol version information.

Failure to do this may result in build warnings and unexpected
behavior when running modules which rely on the ieee80211 subsystem.


-e Aborting the build. You can force the build to continue by adding:

IEEE80211_IGNORE_DUPLICATE=y

to your make command line.


make: *** [check_inc] Error 1


And the "make patch_kernel" mentioned above finishes like this:

The version of the ieee80211 subsystem you have does not include the
Kconfig option for IEEE80211_RADIOTAP. Please download a newer version
of the ieee80211 subsystem from http://ieee80211.sf.net and run:

% make patch_kernel

*or with this driver*, run:

% make add_radiotap

and then try again with this driver.

Aborting.
make: *** [patch_kernel] Error 1

And the "make add_radiotap" throws this error:

The ieee80211 subsystem installed does not provide the necessary files
required for radiotap to be defined. Please download a newer version
of the ieee80211 subsystem from:

http://ieee80211.sf.net/

and run 'make patch_kernel KSRC=/lib/modules/2.6.17-11-generic/build' from that package. You can then
try again.
make: *** [add_radiotap] Error 1


the 'make patch_kernel KSRC=/lib/modules/2.6.17-11-generic/build' doesn't work too and I have the latest version of ieee80211 subsystem. So I suppose problem is somewhere in kernel settings. But I don't have any experience with it and don't know how to do this...
Thank's Vita

Right now I am trying to compile the drivers using gcc and eclipse. It finds like a million errors. May be it's missing some libraries...

I thought that card was supported out of the box....

According to these sites it should be. Actually my card seems to work. System can find the hardware, but it doesn't find any networks although it should find at least 3 networks. Sometimes it finds one, but with no signal...

[Vergil83]

What type of networks are they (wep, wpa, unsecured)?
Try running from the command line (terminal)

iwlist your_interface scanning

I've tried it. It finds all networks, but unable to connect. These networks are unsecured but I'm going to use wpa network

[Vergil83]

If you try to connect to the open networks do you get any errors?

iwconfig interface_name essid "essid_name"
