[SOLVED] How to disable my current (internal) wireless card

Hello,
I have downloaded the aircrack-ng suite from the repository and have been studying the wiki. Turns out the chipset I have isn't supported:
Code: Select all
root[dennis]# lspci -vnn | grep 14e4
03:00.0 Ethernet controller [0200]: Broadcom Corporation BCM4401-B0 100Base-TX [14e4:170c] (rev 02)
....so tomorrow I will buy the highly recommended: Alfa 500mW AWUS036H USB Wireless Adapter 802.11 b/g Network Radio Card. I will plug this usb device and presumably be able to use it immediately, as I see the appropriate driver in: /lib/modules/2.6.33.4-smp/kernel/drivers/net/wireless/rtl818x/
So the question is: must I first disable the Broadcom card? If so, how? And how will the Realtek device show up when I type: iwconfig? Eth0? What I see currently is:
Code: Select all
root[dennis]# iwconfig
lo no wireless extensions.
eth1 no wireless extensions.
eth0 IEEE 802.11bg ESSID:off/any Nickname:"darkstar"
Mode:Managed Channel:0 Access Point: Not-Associated
Bit Rate:0 kb/s Tx-Power=20 dBm Sensitivity=8/0
Retry limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management: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
ppp0 no wireless extensions.
Thanks in advance.

I don't think you need to disable the internal card first. You can do that by blacklisting the module that it uses though. When you get the new card, plug it in and see how it appears, no way to know what it will be before you actually do it I think.

Ok Gapan,
just trying to do my homework ahead of time so that when I get my new toy it will be plug-and-play rather than plug-and-Google.
As always, thanks for the quick and direct response.

As a funny side note: I am now the director of an art gallery here in New Orleans, and the paintings of the artist I represent are similar enough in spirit to the SalixOS desktop that I thought you might want to give it a look. HauntingArt(dot)(com)
Enjoy, and thanks again.

Indeed! Very nice!

These are really great! Thanks.

Ok,
I want to be careful what I ask for here. I am ultimately trying to use aircrack-ng to test (for security reasons) whether or not I can discover my gallery's WEP key from a remote computer. I understand that questions for how to do this are best posted on the aircrack-ng forum.
This said, I frankly like this forum better and so I want to do my basic linux homework here first. So back to my original question, which asked whether or not eth0 and wlan0 would conflict with each other.
Given the info below, can you see an obvious problem preventing me from injecting packets with my new ALFA network card? (By the way, I DID get it injecting packets one night, but I didn't document what I did and my console history doesn't go back far enough.)

I don't see why it shouldn't work, but I don't have that much experience with injecting myself, only done it once or twice just to see what it's about. Google should be able to help you in finding a guide for what you want to do.

Ok. Problem solved.
1) I needed to understand the iwconfig and ifconfig commands which allow etho and wlan0 to be toggled off/on and toggled managed/monitor mode.
2) though I didn't need it here, it was useful to learn that the driver for the PCI device Broadcom Corporation BCM4401-B0 100Base-TX [14e4:170c] (rev 02) is bc44 and can be blacklisted by editing /etc/modprobe.d/blacklist.conf
Thanks for your assistance.
