[HELP] [phy0]SIOCSIFFLAG Error (Cracking WPA2)

[AzureXV]

Hi,

I am trying to hack a WPA2 network, but I am run into trouble because the airodump command is not working.

Here is what I did:

1: airmon-ng start wlan0 -- ( see error [phy0]SIOCSIFFLAG no such file or directory)
2: airodump mon0 --- This fails and says something about no such command.

2a: airodump-ng mon0 -- I try this command and I see another error. --> ioctl SIOCSIFFLAG


Hmm... I dont know what do. My wireless card is: Intel(R) Centrino(R) Advanced-N 6200 AGN --BT4 reads my card as Intel 4965 ... blah blah.

Edit: Here is the full information: 4965/5xxx iwlagn -[phy0]


For the WPA2 cracking I plan to follow this guide:

I Hope you can assist me. TY

Well if you can't be bothered to tell us about your hardware (see above in red) then why should we help you?

Here: faq [Aircrack-ng]

Check your interface name. And if it is up.
And you could give us more details, like all the commands you used and some hardware info.

Im sorry sir. I dont know how to connect BT4 to the internet using my wireless card and the network which is WEP. I had to reboot the PC and enter windows just to get back in the internet so I aplogize for my poor memory skills.

I still would appreciate your help and sorry for bothering you again.

here is the information:

Wireless Card is detected by BT4 as: Intel 4965/5xxx iwlagn - [phy0]

I had that very same error after trying to install a new driver for my usb wireless adapter, you've probably got some kind of conflict of drivers going on.

I would suggest running lsmod and trying to determine which drivers may be causing trouble and removing them.

Heres a link to a similar problem, theres a step-by-step guide for removing and updating a driver:
SIOCSIFFLAG error - Page 2 - Linux Forums

Obviously dont use the driver that they do in the link if yours is different

Hopefully that'll help

I've got this after upgrading to kernel 2.6.34
root@bt:~# airodump-ng wlan0
ioctl(SIOCSIFFLAGS) failed: No such file or directory
root@bt:~#
Previously everything was working fine.

I had the same problem after upgrading. For some reason the firmware file for the 4965 card gets erased during the kernel upgrade. You have to manually copy it back to /lib/firmware
The file you need is called: iwlwifi-4695-2.ucode. Go to this link and download the tar file for the 4695 card: Intel® Wireless WiFi Link drivers for Linux*
Extract the firmware file and copy it into /lib/firmware
Then you should be able to run the following command:
ifconfig wlan0 up

something is wrong in loading the firmware i think, or the driver does not find it, can you give us some informations about your hardware ?

I had this very same problem when upgrading to the latest kernel. For some reason the firmware file for the wifi card gets erased during the upgrade. The file you need is called iwlwifi-4965-2.ucode and you have to place it in your /lib/firmware folder and then execute "ifconfig wlan0 up" without quotes in a terminal window.

You can download the tar file from here: Intel® Wireless WiFi Link drivers for Linux*

My wireless usb card is atheros 5700UG
I'll try the firmware solution given and provide feedback later
Thanks.
