aircrack 2.41 not running with madwifi-ng-r1457-20060228 and Netgear WG511T (Atheros)

guru-meditation · 03-01-2006

Hello,

I just have just successfully build and installed the above mentioned madwifi drivers.
madwifi seems to be working correctly as you can see below.

Code:

When I try starting airodump 2.41, I get the following error:

Code:

root@slax:~# airodump ath0 test
ioctl(SIOCSIWMODE) failed: Invalid argument

ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211
or ARPHRD_IEEE80211_PRISM instead.  Make sure RFMON is enabled:
run 'ifconfig ath0 up; iwconfig ath0 mode Monitor channel <#>'

When I try to manually put the card into monitor mode, I get the following results:

Code:

root@slax:~# iwconfig ath0 mode monitor
Error for wireless request "Set Mode" (8B06) :
    SET failed on device ath0 ; Invalid argument.

Everything was working great (except packet injection), when I used the madwifi drivers, which came with the release 3.0 beta of <<back|track.

Is the current situation a problem of the madwifi release, or my installation of the madwifi release?
Or is it a problem of the aircrack suite and the current madwifi release?
And is there a solution to my problem or problems?

Murphy strikes always!
After dealing with my problem for 2 days, I finally wrote the above post.
2 hours later I solved my problem myself.

"iwconfig ath0 mode monitor" does not work anymore with the new madwifi drivers.
What you have to do instead (if ath0 is already up):

Code:

wlanconfig ath0 destroy

wlanconfig ath0 create wlandev wifi0 wlanmode monitor

The result is:

Code:

root@slax:~# iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

sit0      no wireless extensions.

wifi0     no wireless extensions.

airodump is working again, and aireplay can inject packets.
Mission accomplished.

Have a nice day....

So do you use ath0 or wifi0 as the interface for airodump? I've been messing with my WG511T in BackTrack and it's been making everything freeze while my PrismGT works great.

I use ath0 for airodump and aireplay.
airodump works really great, but aireplay looks not so good.
Attak mode -0 and -1 are working. I am able to authenticate to an AP and I am able to send deauthentication packtes to an AP, but I just do not see any ARP packets and if I use attack mode -2, I will not get the IVs counting up. No matter which packet (provided that is from / for the correct BSSID) I use.

Which card do you haver with the PrismGT?

It's an early Netgear WG511. Most have useless chipsets since they use softMAC but some have fullMAC which are really well supported. I plan on doing the external antenna mod on it one of these days.
