Wireless card on Linux

T-K-O

Hi guys,

I've just recently began to use linux and I'm look for some help with my wireless card.

When i list network adapters it states that i have no wirelesss.. however

lspci

munication controller: Texas Instruments PCI6515 SmartCard Controller
03:03.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)

I can see my wireless device but I can't get it to come up..
Also I have downloaded the drive but dont know how to install..

Any assistance is greatly appreciated..

You do not say what distro you are using, but regardless it should have in its repository the firmware for that wireless device.

dmesg is also useful to see what's going on when the computer starts up.

There's probably an online guide for your particular distro and that particular card. It's a well supported card so it shouldn't cause you too much grief.

Stuxnet

if your on ubuntu, press the superkey and type "additional drivers",
be wired to net via ethernet cable, and it'll downlaod and install your wireless driver and graphics card if needs be

I have the same wifi - works without any problems. Type [1]:

sudo lsmod | grep ipw2200

if there is nothing in the output try:

sudo modprobe ipw2200

If there is something after [1] post the result of "ifconfig" and "iwconfig" (you might have to use "sudo" for it).

Hey,

Thank you for the suggestions..

My job has sent me on a Security Course, part of that course is using backtrack. I've tried BT4/5 but I still have the same problem. I can try the suggestions above when I get home this evening.

One last thing, my understanding is that BackTrack doesnt come with all the nessescary files - would I be better of (as a newbie to linux) installing ubuntu and downloading seperatley the other programs I need for this class?

I have spent several hours on google but couldnt find anything of use Cheers for the guide, ill check it out later
Thanks again

BackTrack is a specialised distro (I never used it), so it might not have the software for everyday use, but I'm quite sure things like "sudo", "modprobe", "lsmod" etc. are there :-) .
For long run use I'd suggest to grab a few different livecds (ubuntu, mint, fedora), test and decide what you like.

humbert

After a quick google it seems that Backtrack should support that wifi card out of the box(possibly without injection).

When you say list network adapters, what do you mean?

Have you tried ifconfig -a?

Do you know how to set up networking on that distro? (I don't know how it's done on Backtrack, whether it's NetworkManager, wpa_supplicant, a net config file)

Ifconfig and ifconfig -a both produce

root@root:~# sudo lsmod | grep ipw2200

cfg80211 160399 2 ipw2200,libipw

but still nothing...

iwconfig

lo no wireless extensions.

eth0 no wireless extensions.


I got ubuntu up and running but I'd really like to resolve this issue..

thanks again..

Hi, any chance you could provide some info about this security course. I'm looking for a useful Security course (unfortunately work won't be paying for it so any help re. standards or open source material used and how it is used in the real world would be much appreciated, PM me if necessary).

In relation to your own problem, you may need to download the linux driver for that card from the Intel site (I had to do this before but it was so long ago I can't remember any specifics - your distribution may or may not already have the drivers required for it, if not, try the Intel site).

Thanks.

What do you get after:

ls /lib/firmware | grep ipw2200

I have:

ipw2200-bss.fw
ipw2200-ibss.fw
ipw2200-LICENSE
ipw2200-sniffer.fw

a next step:

sudo rmmod ipw2200

sudo tail -f /var/log/kernel

and from an other terminal:

sudo modprobe ipw2200

You should see something like that in kernel log:

Mar 22 21:51:14 pldmachine kernel: [ 4508.710144] ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.2.2kmprq

I agree with PrezemoF.

If you run ifconfig -a it lists all network devices, even if they are not up(on). iwconfig lists wireless properties but we're not there yet!

I googled and found this. It indicates that you do have to use modprobe to load the kernel module, then you can configure it to load automatically.

Backtrack is probably jumping in at the deep end as far as learning how to use linux is concerned. There's less documentation on the basic stuff because if you're using it it's probably assumed that you are reasonable savvy.

OP, wifi up&running or you gave up?

He said its a security course not a Linux course, so its probably one of those "demonstration of whats out there and what can be done, but showing you exactly how to get everything working beyond the scope of this course. See SEC505 - Advanced security and Exploits, (another $5K) for how to do that".

Sorry for my cynicism, but I recently got back from a course on pentesting where we spent a day learning to use netcat. Triffic, stuff I learnt in a 2600 magazine about 10 years ago.

As a result of Backtracks usefulness in wireless hacking, it should have every wireless driver under the sun on the disk. Though injection may not necessarily work with out some patching.

I'd be surprised if it took more than:

modprobe ipw2200
ifconfig wlan0 up

The naming convention for the wireless interface may be slightly different.

No I've not given up, i'm taking two courses at the same time and this was eating up a lot of time.. I did follow you advice but I believe the problem is with firmware not installing correctly.. Like I said I'm new Linux and probably making some school boy error.

I came up with a master plan to dual boot Ubuntu on my laptop so I can get familiar with Linux and run backtrack on a virtual machine on my mac, I got wireless via the mac but the pipe key doesn't work

Anyway thanks for the assistance, I'll report back and let you guys know how I get on

Capt'n Midnight

Get a USB wifi card

surf the web or borrow keys to find one that supports injection, avoid Belkin because they re-badge their cards, there is one model there that has FIVE different chipsets :eek: depending on which sub-revision it is

get virtual box from virtualbox.org as the one in ubuntu doesn't include USB support because of rights issues
and backtrack can take control of the USB key from the host computer

I had a netopia that worked, can't remember the model number but it was cyan and transparent

humbert

The one in his computer supports injection on Backtrack though
