edimax with airmon and airodump many interface

[samer]

hi
i plug my Edimax Ew7318usg before booting of BT4
i put my wifi in monitor mode i obtain 2 wifi interface
Wlan0 (for my edimax)
and mon0(???)

i use ifconfig to know from where mon0 it have the same mac adrress and the same configuration as wlan0

if i use iwconfig wlan0 rate 1M
i can't figure any speed rate in iwconfig wlan0 (even 54M)

then i launch airmon and airodump
i obtain some AP but few minutes i can't obtain nothing (i unplug it then i plug it i can obtain AP )

i check iwconfig i obtain :

wlan0
mon0
mon1
mon2
and something like "wmaster0"
(all these interface have the same configuration ,same mac...)

how can i fix the problem of interface

this problem (increasing the number of interface) is not present in
BT3 but the problem of not obtain AP after some minutes has not change (not all the time).
the usb is fine i use it with XP

i can't connect with my BT4 to the internet because of dhcpcd (they say i should download )i put a static ip and i can' t connect ,to tell you exactly what the problem is
thank you

[roblad]

It is normal, because iw is used.

[mfBaranian]

I think you should use dhclient instead of dhcpcd from now on.

[samer]

what step should i take to use properly the interface wlan0 and
mon0 wmaster0... (what interface should i use mon0 or wlan0 or...with airodump,airmon...),i am pluging only one usb wifi (edimax ew-7318usg)

I think that firsto off all you need to figure out what you want to do. Then you should take the time to get to know BT and it's capabilities a little better. I don't know where you are on linux but if you want to use this (i must say magnificent) piece of art you should brush up on that too. It's a lot of work but it pays off.
And please don't just post without thinking. To answer your questions someone would need to write a whole book (plus considering the flames the guys throw around here )
Suggestion - ly low and read all the tuttorials you can find on this forum and that are linked to this forum. You'll get a better picture of what is going on.

And to your question - or at least a part of it.

You should
iwconfig - this will list your wireless interfaces
for airodump-ng you shoud use the interface that's in monitor mode
ifconfig - you will see if your wireless is up

If you can't get around this you should put on your thinking capand get busy with reading.

hi every one and excuse me for the large detail that i enter and thanks very much for any help
this is exactly what i do :

i boot my backtrack 4 from livecd
then i plug my edimax and some time i plug it then i boot BT4 (this problem of increasing of interface is not present in BT3
and in BT3 i use rausb0 and still rausb0 after putting it in monitor mode)
i have only one wifi usb pluged to my laptop

when i remove my usb all the process are the same but i obtain [phy1] in place of [phy0]
like that

BUT if i put ifconfig wlan0 i obtain the real mac address of my wifi usb!!!

13)
and if i put macchanger --mac 00:11:22:33:44:55 wlan0
then airmon-ng start wlan0 the mac address of mon0 is not the same as for wlan0


14)
one time i have put many command but i don't remember exactly the order of commands (i have not update any driver ,and some times i put the wifi usb then i boot my live cd) and airodump-ng have work very very well with no problem at all
and i test the macchanger and i still picking Ap ...(with no problem at all)
(the process of my wifi configuration are well done)??


and excuse me for my large post
and thank's again for any help

[secure_it]

Troublesome post.I could not figure out the whole post as my mind got choked after reading whole.in short the rt73 driver are known as rt73usb now in bt4 and we go ahead with your problem.there are now possibilities like atheros chipset that we can put one interface in managed mode and other one can perform discovery/injection and in case of yours it is wlan0(managed)& mon0(monitor).so if you want to connect to your AP in managed mode just
iwconfig wlan0 mode managed etc. etc.
dhclient wlan0 (dhcpcd is deprecated from bt4)

for working with monitor/injection use mon0
airodump-ng mon0
if you are not getting appropriate results lower the transmit rate e.g.
iwconfig mon0 rate 1M
test with
aireplay-ng -9 mon0
should sort out your problem.

when i put
airodump-ng start wlan0 i obtain :
i have the following

HOW can i kill knetworkmanager and dhclient?

[Lord MuffloN]

kill 7368
kill 8211

Or in other words, kill the PID's of the proccesses.

Or don't do /etc/init.d/NetworkManager start or /etc/init.d/networking start

[SideburnsBaggins]

I have the same card and I think I might have found the solution. Try starting the NetworkManager script.

# /etc/init.d/NetworkManager start
# airmon-ng wlan0 start
# ifconfig mon0 down
# macchanger mon0 -A
# ifconfic mon0 up

I then fired up Wireshark and captured on mon0.

I got a similar list of processes that could cause problems when I ran airmon-ng: knetworkmanager, NetworkManger, and wpa_supplicant; but they did not seem to actually cause a problem.
