reaver freezes on "sending identity response"

[GoogleCodeExporter]

A few things to consider before submitting an issue:

0. We write documentation for a reason, if you have not read it and are
having problems with Reaver these pages are required reading before
submitting an issue:
http://code.google.com/p/reaver-wps/wiki/HintsAndTips
http://code.google.com/p/reaver-wps/wiki/README
http://code.google.com/p/reaver-wps/wiki/FAQ
http://code.google.com/p/reaver-wps/wiki/SupportedWirelessDrivers
1. Reaver will only work if your card is in monitor mode.  If you do not
know what monitor mode is then you should learn more about 802.11 hacking
in linux before using Reaver.
2. Using Reaver against access points you do not own or have permission to
attack is illegal.  If you cannot answer basic questions (i.e. model
number, distance away, etc) about the device you are attacking then do not
post your issue here.  We will not help you break the law.
3. Please look through issues that have already been posted and make sure
your question has not already been asked here: http://code.google.com/p
/reaver-wps/issues/list
4. Often times we need packet captures of mon0 while Reaver is running to
troubleshoot the issue (tcpdump -i mon0 -s0 -w broken_reaver.pcap).  Issue
reports with pcap files attached will receive more serious consideration.

Answer the following questions for every issue submitted:

0. What version of Reaver are you using?  (Only defects against the latest
version will be considered.)
Reaver v1.4

1. What operating system are you using (Linux is the only supported OS)?
BackTrack 5R1

2. Is your wireless card in monitor mode (yes/no)?
alfa AWUS036H (rtl8187)
yes, it is in monitor mode

3. What is the signal strength of the Access Point you are trying to crack?
71%

4. What is the manufacturer and model # of the device you are trying to
crack?

5. What is the entire command line string you are supplying to reaver?
after spoofing my MAC address as in your faq:
reaver -i mon0 -b xx:xx:xx:xx:xx:xx -m xx:xx:xx:xx:xx:xx -c 1 -vv

6. Please describe what you think the issue is.

reaver freezes on sending identity response, I left it for an hour and it did 
not even say timeout error or anything.

I have successfuly cracked too APs with reaver with worse RSSI and with my MAC 
spoofed, so I don't think there is something wrong neither in the signal nor in 
the spoofing.

for tcpdump please see: http://layla.comoj.com/reaver/fail.pcap
I uploaded the file to my website because I can't upload an attachement on 
google.

I can see the AP replying in the file, I think reaver is not recognizing its 
reply.

Thanks for your help. . .

7. Paste the output from Reaver below.

for a screenshot please see: http://layla.comoj.com/reaver/fail.png

Is the router a Draytek ?  If so Draytek's are protected against Reaver :o(

Sorry for being late :(
I don't know if it is Draytek. . .
but I think it is Broadcom, as its ESSID indicates.

would you please see its reply after Sending my identity response(in the pcap 
file) and compare it with that of Draytek?

and How is Draytek protected against reaver if it has WPS implemented??

thanks for your reply. . .

Noone can analyze my pcap file till today!!!

by the way, keyfo according to your Draytek issue, reaver's output is different 
from my case(I don't have timeout errors).
