[Tutorial] Fix: Compat wireless - 'fixed channel mon0: -1'

[hodginsa]

I too have lost all sightings of wlan0, on my broadcom BCM4318...

I had it for awhile but I reinstalled this patch and now its gone completely.

[hodginsa]

I have it working now. What I had to do was uninstall everything, get rid of aircrack 1.1 and install 1.0. reinstall compat with the patch described here except I did this instead.
(Notice the date change, shouldn't matter but its the latest one.) <driver-name> is the driver you use for you wireless card.

./script/driver-select <driver-name>
make
sudo make install
sudo make wlunload
sudo modprobe <driver-name>

but now everytime I restart my computer I have to do

cd compat-wireless-11.01.27
sudo make wlunload
sudo modprobe b43

Anyway to have the b43 driving start up automatically?

[elfandereth]

I am not an expert but maybe you can load b43 adding 'b43' without commas at the end of /etc/modules.

[hodginsa]

Hmm, I thought that might work too and changed it before you mentioned it, but still nothing.

It still loads 'ssb' and 'mac80211' on start up and not b43, because when I do 'sudo make wlunload' it says those two things are unloading.

What should be in my /etc/modprobe.d/options?

I have 'options b43 nohwcrypt=1' I'm not sure why I put that in there.

Whats telling my computer to load ssb and mac80211 and not b43?

[hodginsa]

Okay so I think I got it working. Hopefully this helps someone else.

This works for my case cause I have mac80211 and ssb running on start up. So it may not work for you if mac80211 or ssb isn't on your machine/interfering.

You're going to edit /etc/rc.local (boot up commands)

Sudo gedit /etc/rc.local

add lines before 'exit 0'

rmmod mac80211
rmmod ssb
sleep 3
modprobe b43

the 'rmmod' removes those modules upon startup and the 'modprobe b43' is what I had to enter in manually before but now it waits and enters it automatically.

My wifi starts automatically now.

Hi all,

Working with:
ASUS K50IJ Best buy Edition
Atheros AR9285
Basic kernel drivers, SqurrelScript's Compat-Wireless driver patch.


When i run command:

sudo aireplay-ng -1 0 -a BS:SS:ID -h MY:MA:CA:DD:Y0 mon0

I get "Association successful" with the smiley

But after running:

sudo aireplay-ng -3 -b BS:SS:ID -h MY:MA:CA:DD:Y0 wlan0

I get "wlan0 on channel 14 but AP is on channel 1"

**Side note** when i start airmon i do it like this:

sudo airmon-ng start wlan0 1

My AP being on channel 1, if i dont start airmon like that, I dont get the "Successful" Notif. instead I
get channel error.

Anyone shed some light?

Thanx,

[jd2012]

To any and all it may help, after playing and searching around I found a somewhat solution.

Using:

sudo airodump-ng wlan0 --channel X

Channel X being your AP's channel.
and:

sudo aireplay-ng -1 0 -e SSID -a BSSID -h FAKEMAC mon0

This helped TREMENDOUSLY with staying connected to the AP.
And finally, using aircrack:

aircrack-ng -b BSSID filename*.cap

Instead of:

aircrack-ng -b BSSID filename-01.cap

Worked flawlessly, cracked my NETGEAR in under 5 minutes.

Hoped this helped someone.

[hodginsa]

I was going to mention you were using mon0 you have to use mon0 for aireplay and airodump as well.

I find you should reset the mon0 with the channel you want to use like

sudo airmon-ng wlan0 <channel>

also you can try switching the channel by using

sudo ifconfig mon0 <channel>

But I can't recall

[soad6]

please BUMP... fixed in kernel 2.6.35-25.

After upgrading to Ubuntu 10.10, I found that airodump-ng and aireplay-ng didn't want to work:

OS: Ubuntu 10.10
