wireless lan card in rhel-5

hi ,

i am using rhel-5 version.i am facing some problem in installing and conf of intel ipw 3945BG wireless lan card:here is the complete and detailed output of what i did and the errors :



i installed the above wireless-tools from supplementary cd but when i ran modprobe ipw3945 command,it displays nothing,like

[root@pc1 kernels]#
[root@pc1 kernels]# modprobe ipw3945
[root@pc1 kernels]# modprobe ipw3945 ifname=wlan0
[root@pc1 kernels]#
[root@pc1 k

what does it ?

then i installed and ran ndiswrapper:

[root@pc1 ndiswrapper-1.47]# ndiswrapper -l
w39n51 : driver installed
device (8086:4227) present (alternate driver: ipw3945)

[root@pc1 ndiswrapper-1.47]#
[root@pc1 ndiswrapper-1.47]#

[root@pc1 ndiswrapper-1.47]# modprobe ndiswrapper
[root@pc1 ndiswrapper-1.47]# modprobe ndiswrapper.
ndiswrapper.8 ndiswrapper.spec

[root@pc1 ndiswrapper-1.47]# modprobe ndiswrapper.8
FATAL: Module ndiswrapper.8 not found.
[root@pc1 ndiswrapper-1.47]# modprobe ndiswrapper.spec
FATAL: Module ndiswrapper.spec not found.

[root@pc1 ndiswrapper-1.47]#
[root@pc1 ndiswrapper-1.47]#
[root@pc1 nd

in the readme.txt file included in this ndiswrapper running this command ,where this location should contains include directory and ./config file:

which i checked exists.

[root@pc1 ndiswrapper-1.47]# ls /lib/modules/`uname -r`/build
arch fs kabi_whitelist mm security
block include kernel Module.symvers sound
crypto init lib net symsets-2.6.18-8.el5.tar.gz
drivers ipc Makefile scripts usr

[root@pc1 ndiswrapper-1.47]#

but somewhere i read about linking kernel header file , but i donot know how to do this,

this is what i got from that docs:

ln -sf /usr/src/linux-headers-2.6.15-26-amd64-generic /lib/modules/2.6.15-26-amd64-generic/build

is this required ???and how should i do it ???

You may need the firmware for the ipw3945 wireless using the supplied rpm packages;

Ndiswrapper is not needed.

ndiswrapper not needed...

You don't need to install the ndiswrapper to use your wireless card.

I was able to get it running by following instructions at:

Essentially I did the following..
1) Install rpms

yum --enablerepo=ATrpms install ipw3945 ipw3945d ipw3945-ucode ipw3945-kmdl-$(uname -r)
2) Get the wireless kernel modules working...

shell# /sbin/depmod -a (you only have to do this once, right after installing
the rpms)

shell# /sbin/modprobe ipw3945 (load the kernel module)
shell# /sbin/ipw3945d (start the wireless daemon)
and then the wireless networks appear in the NetworkManager applet.


I had a problem, however, with configuring the eth0 and eth1. I solved it by stoppping the NetworkManager* daemons in /etc/init.d

I then configured the network cards using neat and all seemed to work okay

I then created /etc/init.d/wireless after the above webpage

I added the wireless script to start up routine via command:
shell# sbin/chkconfig --add wireless
It now seems to be working pretty well (famous last words...)

I hope this helps.
