I'm under kernel 3.1.5 with iwlagn driver

Comment 21 by project member cheffner@tacnetsol.com, Today (33 minutes ago)
maguila,

I have not tested the iwlagn drivers, but since you were able to associate I'd 
suspect that injection is working properly. The failed associations and receive 
timeouts are usually an indication of poor signal strength or a lot of wireless 
interference.

The segfault is troubling though. Can you give more info on your OS ?

Comment 22 by gorilla.maguila, Today (12 minutes ago)
I'm using Archlinux x64. We use almost the latest packages on everything as it 
is a rolling release distro.

I have tried to run under gdb but I don't know why I don't get the segmentation 
fault:

Thanks chengzhicn, I was just going through and removing ftpack-struct and 
using #pragma statements where structure packing is critical. :)

Hopefully this will fix the issue, will post when changes are checked in.

OK, removed -fpack-struct and placed #pragma pack statements around critical 
structures. 

I am no longer receiving segfaults in BT RC1 x64 (nor BT RC1 i686, nor Ubuntu 
10.04 i686), nor am I getting the recurring timeout warnings as I was before:

Great, it's working on 64 bit Ubuntu. :D

These are my outputs on rev 20.

At least now is changing PIN's althought I still get WARNINGS.

Thanks for your efforts

maguila, this may be an issue with the AP. Some APs implement WPS a little 
differently and since TP-Link has "QSS" which is not exactly WPS, but is 
supposed to be compatible, I wouldn't be surprised. 

This is what the 'advanced' options are for in reaver - sometimes specifying 
different timeout periods or eap termination options (or others) can help 
alleviate compatibility issues like this. I have run reaver against other 
TP-Links, but probably not the exact model you have, so I can't say for sure.

One silly question;

If I change the build_wps_pin() function to force it to use my PIN, shouldn't 
it work?

Anyway I also tried with the netgear with the same results.

I'm going to download a 32 bits distro and see what I get.

Original comment by gorilla....@gmail.com on 30 Dec 2011 at 3:17

GoogleCodeExporter commented 8 years ago 
Yes, you can change build_wps_pin to always return the same pin.

Let me know if your issues are different in 32/64 bit OSs. It's working fine 
here on Backtrack 5 RC1 32 and 64 bit.

hurenhannes, are you using r20? I have BT5 R1 x64 working with no issues (using 
rtl8187 drivers). 

Also why is your BSSID the same as mine? :)

Issue 5 has been merged into this issue.

yes im using r20. I was lazy, copy paste.... :)

I will try the x86 of BT 5 R1.

Well Good News.

I tried with a 32 bit Ubuntu 11.10 under kernel 3.1.6 also with an old kernel 
2.6.34 on x64 bit system and also with an atheros device with the ath5k driver, 
and I was getting the same results. So it seems it's AP related.

Awesome! These changes are in release 1.2. I'm waiting to hear back from 
hurenhannes before closing the ticket, as he seems to still be having issues.
