Intel pro wireless setup


Hi everyone,
I am COMPLETELY new to linux and am really excited about learning and exploring. I installed Slackware 10.2 yesterday and everything seems to be working great. One problem, however, is my wireless. I have two things showing in iwconfig one is lo(my loopback) and eth0(which appears to be my ethernet).

My wireless is a built-in intel pro wireless 2100. I'm not sure what I'm supposed to be doing. I have used Knoppix and Ubuntu before and the wireless always worked right out of the box.

Im not really sure what (or where) Im supposed to be activating the wireless card. I typed iwconfig already and ifconfig etc etc

When I type lspci -vv I get
02:04.0 Network Controller: Intel Corp PRO/Wireless LAN 2100 3B Mini PCI Adapter

Also
02:08.0 Ethernet Controller: Intel Corp 82801DB PRO/100 VE Ethernet Controller

Ok... which one of these is eth0? Im assuming the PRO/100 ethernet is eth0 because when I plug in a network cable I get the internet. But I can't find the wireless.


Thanks for anyone who can help and I apologize for being such a n00b.

I just had the same issue ... maybe try typing:

dhcpcd eth0 -d

then see if 'ifconfig' shows an IP number for it.

also, maybe to save you some time, to scan available AP's, type:

iwlist eth0 scanning

Mine is ath0 instead of eth0 - (I'm still learning the wifi stuff myself)
good luck

You need to install the kernel modules for the wireless card. To run the latest modules you need to have the 2.6 kernel. Check out http://ipw2100.sourceforge.net/ for the module download and install instructions. If it is helpful I did a tutorial on Slackware and my Dell 600m here, this has my experience and section on the ipw2100 modules . You can also go to http://www.linux-laptop.net/ or http://tuxmobile.org/ to find out stuff specific to your computer. Good luck and enjoy Slack!

Thank you SO much for the tip. Im sure people get tired of answering repetitive questions, but like I said, I read through the forums and didn't find anything that seemed applicable.

One last question... I just installed Slackware 10.2 and read that the kernel that it uses is 2.4.13, but the sourceforge page said that I must have 2.6.8+

So can I use wireless on Slackware 10.2 with the Intel PRO/Wireless 2100?

I appreciate your patience and help.

kernel 2.4.13 is what comes stock. You can upgrade and use whatever kernel you want. The 2.6.x kernels are on the slackware cd's in the testing directory. Just upgrade to the 2.6.x kernel and go from there. You can use upgradepkg to do this. Once you upgrade the kernel you can run the wireless stuff. There are plenty of howto's here about kernel upgrades.

You can also use the old ipw2100 drivers with the 2.4 kernel, but I think the 2.6 kernel is a little faster.

post back if you have any probs/quest. Just make sure to be careful upgrading the kernel, follow the directions and you will be fine.

Also, at least with the ipw2200 (not sure about 2100), you'll need to download the ieee80211 package, run the 'cleanup utility', and then compile and install it to use the latest version of the 2100 driver. The kernel is using an older ieee library than the 2100 requires...

I'm a little upset that they changed that in newer versions, since the installation has become more difficult. I suppose there are advantages though. I just don't know what the limitations of the old library versus the new are.

Rather than using "upgradepkg", I suggest that you use "installpkg" to install the 2.6 kernel related packages:

Code:
installpkg /testing/packages/linux-2.6.13/kernel-generic-2.6.13-i486-1.tgz
installpkg /testing/packages/linux-2.6.13/kernel-modules-2.6.13-i486-1.tgz
installpkg /testing/packages/linux-2.6.13/kernel-source-2.6.13-noarch-1.tgz
installpkg /testing/packages/linux-2.6.13/alsa-driver-1.0.9b_2.6.13-i486-1.tgz
This allows you to keep using the default 2.4.31 kernel along with the new 2.6.13 kernel.
Read the /testing/packages/linux-2.6.13/README.initrd file about why you do not have to install the kernel-headers package too.

One more thing to do, and that is to tell the bootloader LILO to add a menu entry for the new kernel: edit
Code:
/etc/lilo.conf
and add something like these lines above the entry for your 2.4 kernel:
Code:
image = /boot/vmlinuz-generic-2.6.13
  root = /dev/hda1
  label = linux-2.6
  read-only # Non-UMSDOS filesystems should be mounted read-only for checking
- save the file and then run the command
Code:
lilo
to activate your changes.
If your root filesystem is on another partition than my example "/dev/hda1" then change that before you save the file. The existing entry for the 2.4 kernel should tell you what to type because that entry should look almost identical.

The 2.6 kernel will now be the default selection in the LILO boot menu. If you want to alter that, you either place my example lines below the entry for the 2.4 kernel, or use the default = parameter in the file (read "man lilo.conf" if you need to know more).

Alien Bob,sorry to interrupt.

I am also wondering how to setup the Intel Proset on my notebook. I have just read your post said that it's possible to install another kernel from slackware website without compiling from the sketch. Is the kernel maxmize on its performance?Is that kernel bulky?(e.g. Lots of unneeded modules).

Thanks for your concern.

if you want to maximize your kernel for performace you will need to compile it yourself. This is always the case as everyone has different hardware. The stock slack kernels have most everything as modules that load as needed.

I looked through my directory after installing slack 10.2 and couldn't find /test or /testing or anything that remotely looked like what you described. Did I get a bad install or do I need to look on the actual install cd?

The pre-compiled 2.6.13 kernel that comes with the official Slackware 10.2 CD set or can be downloaded for instance at http://slackware.mirrors.tds.net/pub.../linux-2.6.13/ is built just like the 2.4 series: a relatively small kernel with most of the functionality built as kernel modules.
If you build your own kernel, no doubt you can tweak it so that it runs better that Slackware's default. But for anyone who does not want to start compiling a 2.6 kernel from scratch, you can install the 2.6.13 kernel sources along with the kernel itself and use Slackware's .config file as a start (it will be installed as /boot/config-generic-2.6.13 ).

Eric,thanks for your reply.

I did compile my kernel from scratch before. It takes time and sometimes you don't know what's the meaning of some modules. You get to the point that you don't know whether you should include/exclude that modules. As a result, the compiled kernel was compiled without some functionality(e.g. my battery meter is not working).

Thanks for your attention. Maybe I should consider using default kernel.

I noticed that the latest 2.6.14 kernel includes the intel wireless drivers.

Swift,

Learning how to compile a kernel definately takes time and practice. Making the decision to learn is simply deciding how much free time you have to mess with it. The first couple times you will definately leave things out, which means another recompile. It is worth the time to learn though. Once you do it a couple times it become second nature.

I did not see the wireless drivers in 2.6.14.3 but have noticed references to them in 2.6.14-git14. So they should be floating around soon.
