I tried to write a work-around for the Intel 4965 chipset.  When I wrote 
wifite, the 4965 chipset was not able to fake-authenticate using aireplay-ng 
(-1), so I wrote a small method that used wpa_supplicant and a fake .conf file 
to fake-authenticate with the access point.  

The testers claimed that the script worked with the intel 4965 chipset in 
Backtrack 4.  My guess is that Ubuntu 10.04 does (or doesn't do) something that 
Backtrack 4 does -- perhaps the drivers are different, or ... hmm...

I can try to write a fix so that the program does not crash when 
fake-authentication fails. However, this means that fake-authentication will 
still fail, so maybe you aren't close enough to the router...

If you ARE close enough, maybe it's just a problem with Ubuntu 10.04 since the 
script apparently works for BT4.  I don't want to 
code-upload-troubleshoot-repeat for a chipset I have no access to (it's a big 
headache for me).  The only fix I can offer is that the program won't crash 
completely...

In the mean time, you could boot into a Backtrack4 Live CD/DVD/USB and use that 
operating system (since wifite was designed for BT4), try different wireless 
drivers (probably won't help) or try a different wireless device (the ALFA 
awus036h is amazing and ~$30).

Sorry, this probably isn't what you wanted to hear. 
I'll post a link if I [may have] fixed it.

Just committed r62. I tried to catch all exceptions, including the Pexpect and 
OSError.
Hopefully the new version doesn't crap out on you...

python wifite.py -update

Hi,

first, thank you for the fast response. Very good :)

I updated to r62 and now I get a "new" error. It looks like the script hangs at 
the 2nd attempt.

Yikes, that looks like a different bug in the same area. I'll look at it later.

Thanks for replying. You don't need to start new issues: I can see whenever a 
new comment is posted -- I just haven't had time to check recently.

Ok.  I added more error-handling and committed r63. Hopefully this will stop 
the error :\

I really hate debugging for hardware I don't have.  If I had a iwl4965, this 
would've been done long ago and I wouldn't have to waste your time >;[

Hi,
I think I have a similar problem.
When I trie to work with a WEP encrypted network I have a issue with pexpect.
Pexpect need python but only on 2.5 and I'm on 2.5 so it don't whant to be 
installed and I can't start WEP cracking.

I get this error in Backtrack 5.

On the latest revision the wpa_supplicant workaround doesn't exist  , can yu 
please re add it
