I need some help with hardware issues etc.

[branndenb]

I currently am a "newbie" but im starting to catch on to some of this.
I have backtrack 4 on a bootable USB drive and i can get it running.. but i type int he command- airmon-ng it doesnt show anything under interface or anything.
my network card is a broadcom 802.11b g
Is it at all possible to get this to work on backtrack 4??
if so, can someone help me through it or atleast direct me to a thread/tutorial.
thanks a lot guys

Would be a lot easier if you could post the exact output you get. (But it's more likely that your card is not supported out of the box.)
Assuming it's a Broadcom 4312 type in this command
lspci -vnn | grep 14e4
Compare the output with info here and here.
Keep catching on.

Thanks for the reply,
i followed that code and i got the result
14e4 4315

its says supported after a certain version...

because i am new to all of this i would like someone to help me if possible, just to get me started.. what should I do first?

[mfBaranian]

I would suggest to sit and wait. To get b43 support you need to upgrade to 2.6.32.x kernel. The bt4 currently runs on 2.6.30.9. Upgrading would mean taking the linux image (e.g. kernel) from an outside source, would require you to have at least a solid understanding of how linux works and would inevitably brake your system (since it's not supported yet).
What you could do is force it to work without injection capabilities (meaning only for surfing the net....kinda like windows, and no fun part - poking and braking your own network). Don't worry BT4 is much more than that.
Check this.
Or you could get some other wireless card (consult with the hcl thread).

It does state in the links that #mfBaranian# provided, that 4315 is supported. And (at least some) kernels prior to 2.6.32.x are also.

Is my Brcm device with PCI Device ID XYZ Supported?
These PCI Device IDs are supported:

Device ID Product Name
--------- -------------
0x4311 4311 2.4 Ghz
0x4312 4311 Dualband
0x4313 4311 5 Ghz
0x4315 4312 2.4 Ghz
0x4328 4321 Dualband
0x4329 4321 2.4 Ghz
0x432a 4321 5 Ghz
0x432b 4322 Dualband
0x432c 4322 2.4 Ghz
0x432d 4322 5 Ghz
0x4353 43224 Dualband
0x4357 43225 2.4 Ghz


ISSUES FIXED AND WHAT'S NEW IN THIS RELEASE
-------------------------------------------
+ Supports Linux kernel 2.6.29, 2.6.30.1, 2.6.31
+ Supports hidden networks
+ Supports rfkill in kernels < 2.6.31

I would try from a terminal, plain old:

modprobe b43

Then retry

airmon-ng

BT4 Final and later does support the Broadcom cards, at least the one I have been using. I currently use an Asus WL-138G V2 card and it works very well with BT3 -BT4F.

01:04.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.
11g Wireless LAN Controller (rev 02)
Subsystem: ASUSTeK Computer Inc. Device 100f
Flags: bus master, fast devsel, latency 32, IRQ 16
Memory at ed110000 (32-bit, non-prefetchable) [size=8K]
Kernel driver in use: b43-pci-bridge

One of the first things you will want to do is make sure you have enabled the Network, go to Services/Network and "Enable Network".

There are 2 methods to putting the card in monitor mode:
1. In a shell type: iwconfig wlan0 mode monitor. You may need to change the zero (0) to a whatever your is.
2. 2nd method, in a shell type airmon-ng start wlan0. This will create another device called mon0. This is the device that you will use since it is the device that is in "monitor" mode.
Hope that helps.

before you do all of that stuff, try turning the card on with ifconfig wlan0 up or ifconfig eth1 up
then type in ifconfig alone to see if its turned on

because this is a pentesting distro, networking is not turned on by default so you must turn it on.
To do that go to the start button in the bottom left, select services, then networking, and turn networking on


if these steps don't work for you then its time to start troubleshooting drivers etc...

@ HappySmack
Yes they are but without injection capabilities.
@ Marcinko
Yes some are supported, but branndenb's has a specific ID (14e4:4315) and can't inject (at least not with the current BT4 kernel).
