wireless network issue - Intel iwl3945 driver


I apologise for posting yet another wireless networking problem. I know they come up all the time.

I've not posted without spending considerable time trying to sort it myself but i'm stuck and need a bit of advice.

I've followed what seems like a lot of earlier posts about this but still must be doing something wrong.

I'm using slack 12.1, linux 2.6.24.5-smp.

Code:
lspci: Network controller: Intel Corporation PRO/Wireless 3945ABG
the iwl driver is installed by default with slack 12.1 i believe:

Code:
lsmod | grep 3945
iwl3945                88424  0
mac80211              122124  1 iwl3945
I've read where others have reverted back to the ipw3945 driver to overcome the issues they had, but it seems like an easier option to use the driver that's already installed?

The wireless card is being picked up, shown by:

Code:
iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wmaster0  no wireless extensions.

wlan0     IEEE 802.11g  ESSID:""
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated
          Tx-Power=27 dBm
          Retry min limit:7   RTS thr:off   Fragment thr=2346 B
          Encryption key:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0
So, i'm not sure exactly what steps i need to take in order to this up an running. eth0 (hardwired) is fine.

Would someone mind giving me some pointers so i can get this sorted?

Try a newer version of the driver:

it looks like your driver works fine as the card is being given an interface (wlan0) you need to edit the file /etc/rc.d/rc.inet1.conf to change the settings applied to the card. Before you try that try something like:
Code:
iwconfig wlan0 essid "your essid here"
ifconfig wlan0 up
dhcpcd wlan0
which should make your card associate with your wireless access point (this is assuming no security), if you are using security you will need to read up on what you need to put in /etc/rc.d/rc.inet1.conf - once you have edited this file you can make it be re read by doing:
Code:
/etc/rc.d/rcinet1 restart

Cheers for that tip. I've had a look at the site and its links to the intel site, etc. I have read through them before but they're useful to refer to anyway.

I don't think that installing a newer version is what i need though. It seems i can bring the interface up from the command-line with

Code:
ifconfig wlan0 up
      iwlist scan
of course then adding in the necessary ESSID and wep key. The card does scan ok and shows a list of routers i can connect to. When i'm in X (kde) and open some of the gui wifi apps like Kwifimanager, or 'control center > internet and network > network settings' i get nothing other than a pop-up saying "your platform is not supported" with a list of other linux platforms to choose from. Slackware versions 9.1 to 10.0 are there. So i'm not sure why that might be. Perhaps the problem i'm having is a more x related issue?

Any ideas?

Thanks tdos20.

must have been typing when you posted so just got it. I can run those commands fine and bring the interface up. I've not changed
Code:
/etc/rc.d/rcinet1 restart
yet (will do that next) as i wanted to get some info from the forum before changing things.

OK. I got it connected after changing /etc/rc.d/rc.inet1.conf

I rebooted as well and i get a wireless connection.

I still can't use any of the x tools/apps to scan and connect to networks, nor to show any information about the ethernet connection.

Maybe not, but I have the same network card and it's what I needed.

I thoroughly analyzed my problems with the kernel iwl3945 driver and documented my findings in this thread:
http://www.linuxquestions.org/questi....inet1-646272/

The problems do not exist with the newer driver.

Thanks Dugan. I've just been reading that one funnily enough and i think you're right. I'm going to try what you did.

Just one other question: when i run /etc/rc.d/inet1 restart, i get this message:

Code:
Error for wireless request "Set Nickname" (8B1C) :
    SET failed on device wlan0 ; Operation not supported.
Polling for DHCP server on interface wlan0:
I don't know what this means. Was this put right when you installed a newer driver?

Nope. I still get that message, even with the new drivers.

I think that eror message is from using
Code:
IFNAME[4]="wlan0"
in /etc/r.cd/rc.inet1.conf as not all cards support changing the interface name, you may not need it but I don't think it does any harm.
