LE2005 & Acer Centrino Laptop Wireless Connection

[tsm405]

Hello Everyone

 

I have a LE2005 on my laptop Acer TravelMate 4052 (Intel Centrino 725 with Intel Pro 2200 wireless support).

 

I am unable to get my wireless LAN connection up and running with a Netgear WGR614 box

that is actively connecting other laptops (win/xp) wirelessly.

 

Here are some of the things that I have been doing to fix this (after ensuring that the

wireless subsystem is on - Acer has a explicit hardware switch on the laptop for it):

a ) Use MCC to add a new wireless connection but it fails after trying to take the parameters for a wireless connection,

b ) used the MCC hardware detection unit to check if Intel Pro 2200 is there - it is. Configured it with default parameter values. Still network connection not up

c ) used lsmod to check if ipw2200 module is installed - found it missing. So did an

' insmod ipw2200.ko ' after untarring the zipped file present in

' /lib/modules/2.6.***/kernel/3rdparty/ipw2200... '

Insmod suceeded and lsmod now lists the module ipw2200.

d ) Did a iwconfig and found that it gave a standard message : ' No wirelss extensions' on eth1.

e ) Did a ipconfig -a and found that eth1 is listed but without any ip address.

f ) rebooted the system and found that system defaults to initial state (with lsmod

showing no ipw2200 module.

g ) tried downloading and compiling the latest ipw drivers from sourceforge.net

- -make failed due to dependencies *ieee80211 etc...

 

Can you help? What steps do I take to get this wireless connection up?

 

thanks a lot in advance

According to here it's certified OK.

Have you tried the intel website for the wireless drivers?

Hi

 

Thanks for a quick reply,

 

Yes it is the certified Intel Pro 2200 b/g wireless that the Intel Centrino support....

Also the intel drivers website leads to the ipw2200.sourceforge.net from where

I had downloaded the latest ipw2200 drivers for compilation (it failed because it

demands that we compile ieee80211 from ieee80211.sf.net which I downloaded

and tried compiling - that failed because it is seeking a '/lib/modules/2.6*/kernel/build'

directory that does not come as part of LE2005 distribution that I picked up..

 

Look forward to help from everyone...

 

thanks a lot....

Do you have your kernel-source installed? It could be that it's failing finding it.

 

If I'm suggesting something now you've already done, then please forgive me :P

 

First, type uname -r to give the version of kernel your running, then urpmi the kernel-source based on the current kernel installed.

 

Eg, if running kernel-2.6.11-6mdk then you would do:

 

urpmi kernel-source-2.6.11-6 (or whatever the exact name is).

 

Or alternatively, use System/Configuration/Software/Install Software, choose All option, then find kernel-source that matches exactly if you prefer the GUI method for installing.

Hi Ianw1974

 

Thanks for these suggestions. No I have not installed the kernel source!

Are you suggesting that I go the path of compiling the latest ipw2200 drivers

from sourceforge.net and plugging it in the right place so modprobe at boottime

will automatically detect it and my wireless connection gets activated? And therefore

do you suggest that I install the latest kernel sources ( am using 2.6.11-6mdk-i686-up-4GB)

and recompile?

 

Has this been a problem with other Intel Centrino laptops? (and this the prefered approach?)

 

Look forward to your inputs

 

Thanks a lot

[ianw1974]

When you compile stuff such as this ipw2200 or video drivers, it requires the kernel-source to be installed so it can compile and work.

 

Hopefully, once installed, and you compile as you did previously but with the kernel-source installed, all should work a treat! :P

[tsm405]

Hi ianw1974, (and others)

 

Here is a long report on what I did - kindly take time to figure out whats going wrong....

 

Request your patient reading... and helping me out...

============================

After downloading the kernel sources:

 

[root@Achintya ]#urpmi kernel-source-2.6-2.6.11-6mdk.i586.rpm

 

It got successfully installed.

 

============================

After downloading from ieee80211.sf.net,

This was successful!

=================================

From ipw2200.sf.net I downloaded the latest ipw2200 drivers, unzipped and untared.

Then:

Don't forget to copy firmware to your hotplug's firmware directory and have the
hotplug tools in place.
See INSTALL for more information.

===========================================

Then I went thru INSTALL text file in the ipw2200 package downloaded

Followed the instructions for hotplug installation

 

Downloaded ipw2200-fw-2.3.tgz, the firmware from

http://ipw2200.sf.net/firmware.php

and put it under /lib/firmware/ipw2200

 

Downloaded and tried installing:

>>urpmi hotplug-2004_03_29-1.noarch.rpm

with the results "The package(s) are already installed"

 

In the directory where ipw2200.o was compiled, I did a

% ./load

which resulted in the following:

After rebooting the system I did

Going to the above directory I find that ipw2200.ko exists and doing a

'strings ipw2200.ko' yields the version 1.0.6.

 

Doing a 'lsmod' now fails to list 'ipw2200'

===========================================

 

I tried using Mandrake control center to add a new connection (wireless connection)

It failed (goes into a infinite loop trying to load after asking for ipw2200 driver

installation)

I tried reconfiguring the network connection - that also fails.

I tried 'wireless connection'option of Network & Internet of MCC - that just starts and exits the 'drakroam' program.

========================

 

So where have I failed out? What else do I need to do?

How can I get my wireless setup working

Look forward to all helpful inputs

 

Thanks a lot in advance

I haven't tried this myself (I don't have the same wireless card), but this guide may help you.

Hi

Thanks for this input. I went thru the guide (it was for Mandrake 10.1 wireless)

I did create the /etc/firmware as well as /lib/hotplug/firmware and copied the

contents of ipw2200-fw-2.3.tar

 

Then I did a Menu->System->Confguration->Configure your computer and tried setting

up a new connection (wireless connection). It started by asking for identifying the

driver manually, and prompting for parameter values (manual or autoprobe). Both

ways, pressing the next button reverts back to the 'identify the driver manually'screen.

A kind of infinite loop. Only way out it to cancel the setup.

 

No luck :-(

 

Thanks and look forward to more inputs

[tsm405]

Hi All

I just wanted to add a few more points to my earlier posting:

1. From Mandrake Control Center (MCC) I was able to detect the wireless hardware to be functioning.... (hardware detection list)

2. The eth0 ethernet connection thru the 10/100Mbps cable connection works perfectly fine...

3. The wireless hardware is switched on (Acer laptop has an explicit switch)

when I did the ipw2200 related work (compilations, installation, modprobe etc)

 

Have anybody successfully used the wireless support in LE2005 on an Intel Centrino laptop

(Intel Pro 2200 wireless)?

 

Thanks in advance.. waiting for all Mandriva Gurus to respond.

B)

[tsm405]

Hi Folks,

 

Much before experimenting unsuccessfully to this level, I have been several other pages with

similar IPW2200 problems on this forum. However none seem to be helpful...fully.

 

Here are my key questions:

1. Does anyone having a centrino based laptop running SuSE 9.3 been successfully using the wireless

connection?

2. Has anyone seen somebody else do it?

3. If there are indeed successful installations - can we request information sharing..................

 

Mandriva Gurus..... looking forward to your inputs (waiting a bit impatiently)

 

Thanks a lot in advance

HI Everyone,

 

After experimenting with several Linux distros (Mandriva LE2005, SuSE 9.3, Ubuntu 5.04) I have

successfully solved my wireless connectivity problem.

 

Here is the summary of it - so others may benefit:

 

Kindly lookup: http://forums.suselinuxsupport.de/index.php?showtopic=19871

for details on how I did it successfully using SuSE 9.3 Pro.

The IPW2200 drivers  on Acer tms 4052NLCi (Intel Centrino 725) Laptop

  was successfully installed as follows:

 

  REMEMBER:

    -- Any parameter mismatch will result in the wireless connection not working.

    -- The sequence of execution of commands is very important (always start with

            a fresh installation and do a ./remove-old (see below) before compiling

            and installing ieee80211 or ipw2200 drivers.

    -- Compile and Install wpa_supplicant correctly

    -- Use the correct parameter settings to configure the wireless connection.

 

Procedure:

1. Install freshMandriva LE 2005  (and (choose packages to install manually)

add up all kernel dev/source / headers files too during the installation)

2. Download from ieee80211.sf.net as well as ipw2200.sf.net (including firmware)

Firware is available at : http://ipw2200.sf.net/firmware.php.  Kindly unzip

and copy to /lib/firmware directory as root.

3. Unzip and untar the sources.  Go thru the README / INSTALL files - but do not

get confused.

4. Go thru readme (including the guide by Luca_Linux on Ubuntuforums.org on

how to setup wireless on laptop: URL: www.ubuntuforums.org/showthread.php?t=26623)

5. Do a ./remove-old from ieee80211 dir as well as ipw2200 directories

  with no errors. (Manually check out all the paths that these makes throw up).6.

  Then do a rmmod ipw2200 for all the drivers to be removed from kernel.

7. A lsmod | grep ipw will show if kernel has go it still (there should be none).

8. Go to ieee80211 directory  and first do a make and then make install. No errors should

    show up.

9. Do the make and then make install from within ipw2200 directory. Again no errors

    should be there.

10. Do a modprobe ipw2200 - this should take in the new drivers into the kernel.

11. Configure the network cards - both cards: Set up the wireless parameters correctly:

    Managed mode, Known ESSiD, correct WPA_PSK shared key, and correct passphrase.

      as well as static/DHCP IP address settings  and correctly local GW ip address as

    well as nameserver ip addresses.

  Set the advanced->settings to cable connection for eth0 (lan card) and manual with user

    control for the eth1 (wireless) card.

12. Reboot the system and then do a dmesg| grep ipw  This should yield the version of the

    driver in the kernel.

13. Use Kinternet tool to try connecting up  - signal detection shows but will

    not connect. - Click and select the available network and then try to 'connect' it.

14. Add the wpa_supplicant code (Download from the internet wpa_supplicant.0.4.5.tgz --

  (URL: http://hostap.epitest.fi/releases/) See for the latest version of wpa_supplicant

  sources there. Compile it after configuring the wpa_supplicant.conf file correctly

    (In my case except the IPW drivers almost everything else was commented out - EAP etc etc)

15. Compile and follow the instructions in it.

16. Put in the /etc/wpa_supplicant.conf as well as the /etc/init.d/wifi_qpa.sh

    (see the ubuntu URL above)

17  Reboot system and check out: iwlist eth1 scan; iwconfig; ifconfig....

18. As root, Do a ifdown eth0 (wireline), a ifdown eth1 and then a ifup eth1.

  You cannot keep both the network interfaces up simultaneously.

   

  Everytime you boot up and want to connect wirelessly, do a su on a console terminal

  and do the above - ifdown on all network interfaces and ifup on the wireless interface.

  Perhaps in the next edition of  Mandriva (or SuSE or Ubuntu) this should get fixed.

-------------------------------------------------

 

 

IMPORTANT:  a) Use WPA_PSK  as the authentication mode  in both the wireless

  router as well as in YaST configuration...

 

--------------------------------------------------------

 

So why did I have my earlier problems? Here are the reasons:

1) I did not get the right kernel header files for ipw2200 compilation

    (My downloaded kernel source version had a minor mismatch with what was

    installed - so I reinstalled manually (not the standard option) specifically

    marking out all packages to be installed (including kernel headers).

2) I did not follow the right sequence in terms of driver compilation.

    (First do a ./remove-old and then do a make followed by make install.)

3) Ensure that any error messages are looked into.

4) Ensure that once a cleanly installed system gets messed up by these wrong

  leads it only complicates matters further (there are several side-effects

  of any failed driver installation procedures... as not so deep hackers,

  we do not know what system files    are left in what state...)

5) The System GUI many times royally screws up the configuration process

    (YaST would not show some of the parameter screens and Mandrake Control centre

    got totally messed up - it used to go into an infinite questionaire loop).

6) I read through several URLs and Pages of apparent help - the Ubuntu forum

    was very helpful (45 pages of discussion on this one topic)

  Thanks Luca_linux @ ubuntuforums.org.

 

Thanks Ianw1974 for all your inputs. Thanks to Qchem too..
