Installing WIFI intel 4965 AGN

[Romano]

Hello All,
I have a ASUS V1S series laptop with a intel 4965 AGN for wifi card.
I don't really know how to install wifi on it because it doesn't work.
I tried this : http://www.linickx.com/archives/291/intel-3945abg-wireless-wifi-card-on-centos-5#comment-10074
...... But nothing happened...
Can someone help me ?
Thx a lot

You need to have the dkms-ipw3945, ipw3945d and ipw3945-firmware packages installed. Follow the instructions here;

http://dag.wieers.com/rpm/FAQ.php#B

When ready as root type something like: yum install dkms-ipw3945 ipw3945d ipw3945-firmware
Warning the list is not complete but should be good enough to also install was is missing/needed/required lke dkms for example.

Hello thanks for your answer,
Here are the installed packages on my centos 5.
Installed Packages
dkms-ipw3945.noarch 1.2.1-1.nodist.rf installed
ipw3945-firmware.noarch 1.14.2-1.nodist.rf installed
ipw3945d.i386 1.7.22-4.nodist.rf installed
But wifi card still not recognize...

Please check the output from the typed command; /sbin/lspci -v

Check the /etc/modprobe.conf file for a line entry like: alias eth1 ipw3945

Review the /var/log/messages file for any clues.

You may need to configure the interface also, have a look in hare in this forum (CentOS 5 - Networking Support ) for possible assistance.

Hello,
First Lenard, thanks a lot to help me !!!!

For the /sbin/lspci -v, here is the thing about Network controller

04:00.0 Network controller: Intel Corporation Unknown device 4229 (rev 61)
Subsystem: Intel Corporation Unknown device 1101
Flags: bus master, fast devsel, latency 0, IRQ 10
Memory at fdffe000 (64-bit, non-prefetchable) [size=8K]
Capabilities: [c8] Power Management version 3
Capabilities: [d0] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable
-
Capabilities: [e0] Express Endpoint IRQ 0

For /etc/modprobe.conf, here it is

alias eth0 e1000
alias scsi_hostadapter ahci
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel

I did not find anything look like network in /var/log/message....

What do u think ?

This device [b]04:00.0 Network controller: Intel Corporation Unknown device 4229 (rev 61)[/b] is your wireless interface. You also seem to have a 'wired' network interface (alias eth0 e1000).

As root edit the /etc/modprobe.conf file lets add an alias for the wireless device, any text editor will do. Add a new line entry just below the alias eth0 e1000 line entry which looks like: alias eth1 ipw3945

Now create an ifcfg-eth1 file, here is a sample copy it belongs in the /etc/sysconfig/network-scripts directory. Feel free to cut and paste, the file name once again is ifcfg-eth1 and is saved in the /etc/sysconfig/network-scripts directory;

[code]
TYPE=Wireless
DEVICE=eth1
HWADDR=
BOOTPROTO=dhcp
IPADDR=
NETMASK=255.255.255.0
GATEWAY=
DHCP_HOSTNAME=
DOMAIN=
ONBOOT=yes
ONHOTPLUG=no
USERCTL=yes
IPV6INIT=no
PEERDNS=yes
ESSID=
CHANNEL=
MODE=
RATE=
[/code]

When done restart the network service: service network restart
or reboot the laptop.

Use iwlist eth0 scan to get additional values for the ifcfg-eth0 file.

Hello Lenard,

I think i am close to achieve to make it work but it still doesn't work.
I followed your instructions and i have this now.
When i restart service network or reboot the laptop, i have this message :

[root@br162-138 network-scripts]# service network restart
Arr?t de l'interface eth0 : [ OK ]
Arr?t de l'interface loopback : [ OK ]
Activation de l'interface loopback : [ OK ]
Activation de l'interface eth0 :
D?finition des informations IP pour eth0. fait.
[ OK ]
Activation de l'interface eth1 : Le p?riph?rique ipw3945 n'?tant pas pr?sent, l'initialisation de eth1 sera retard?e.
[?CHOU?]
[root@br162-138 network-scripts]#

And when i use iwlist eth0 scan i have the following

[root@br162-138 network-scripts]# iwlist eth0 scan
eth0 Interface doesn't support scanning.

What to do ?
Thanks again for your posts and your help.

First sorry, my mistake ...........

The command should be(for the wireless device): iwlist eth1 scan

Second, if you have encryption enabled on the wireless access point/router turn it off for now, until you get a connection while testing.

Some routers do not play nice with Linux, you may want to add some values to the ifcfg-eth1 file. The GATWAY and ESSID values should have the wireless routers internal IP address and broadcast name respectfully.

Examples:
GATEWAY=192.168.1.1
ESSID=MyRouterName

Lastly both the network interfaces should not be active at the same time on the same subnet (192.168.1.XXX) so one may want to also change to ONBOOT=no in the ifcfg-eth0 and/or ifcfg-eth1 files then try bring down one interface before activating the other. For example;

ifdown eth0
ifup eth1

[Romano]

Lenard,
here is the result of scan

[root@br162-138 ~]# iwlist eth1 scan
eth1 Interface doesn't support scanning.

?????

I my apology for getting back so late on this.

You may want to check if the wireless driver is loading or not;

cat /proc/modules | grep ipw

If not then try manually loading, as root;

modprobe ipw3945
/sbin/ipw3945d

But I also see;
http://www.centos.org/modules/newbb/viewtopic.php?topic_id=10840&forum=40&post_id=34909#forumpost34909

Which suggests trying the ipw2200 driver and firmware.

Also please use the Search feature on this site and search for iwp3945, wireless, 4965 and such.
