Constant receive timeout (0x03), or WPS transaction fail (0x02) with rtl8187

[GoogleCodeExporter]

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

Revision 112 from svn.  Problem has occurred with all previous builds tried.

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

Both BT5 R1 (kernel 2.6.39.4) and Ubuntu 11.04 (kernel 2.6.38-13).

2. Is your wireless card in monitor mode (yes/no)?  Yes.  Injection is working, 
and aireplay-ng --test verifies test AP is in range.

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

Range tried varies between -40 and -65.

5. What is the entire command line string you are supplying to reaver?

Tried:

reaver -i mon0 -vv -b <mac>
reaver -i mon0 -vv -b <mac> -a
reaver -i mon0 -vv -b <mac> --no-nacks
reaver -i mon0 -vv -b <mac> -d 5
reaver -i mon0 -vv -b <mac> --no-nacks -d 5

For the output and pcap provided, the command line was:

reaver -i mon0 -vv -b <mac> -a

6. Please describe what you think the issue is.

I have no idea.  If it were a rtl8187 driver issue, I believe google would have 
turned up better results.

7. Paste the output from Reaver below.

Try running Reaver with the --no-nacks argument.

Thanks cheffner.  I left reaver running overnight with the --no-nacks argument, 
and I do appear to be making progress.  Pin attempts are incrementing, and I 
see the xmit of M2, M4 and M6 messages, as well as the receipt of M1, M3 and 
M5, where previously I had only seen timeouts.  I do however also see many 
failures to associate.  I'm at around 91% now, and will wait for the process to 
complete before following up with an additional output or pcap dump.  Anything 
else to be considered?

Given your output that you posted, it looks like the AP is having trouble 
seeing your packets. This won't stop the attack, but will obviously slow it 
down (although it sounds like you've already cracked the first half of the pin, 
which is 90% of the battle!).

Even with a good signal this can sometimes be an issue depending on the quality 
of the AP's receiver and any local interference. Really the best you can do is 
try to get closer or boost your signal with a directional antenna.

I'll look further into tx.

My last run did finish with a successful PIN, but no PSK was returned.  
Regardless, this is progress, and I will continue to work on range and the 
--no-nacks argument.  Thank you!

Hmmm...are you sure the target AP is using WPA encryption?

Hi

I am also experiencing this problem.

I have used Reaver quite a bit recently without any serious problems so I would 
say I am familiar with it.

Today was my first real trouble and it seems to be the same as this post.

reaver -i mon0 -c 6 -b 00:50:3F:A5:EC:70 --mac 62:29:d9:80:e4:e7 -vv

None of which work.  The AP is a Draytek.

Wash shows that the my AP has WPS enabled and it is not locked out.  I have a 
signal strength of between -58 and -63.  I can usually get a very good transfer 
rate with this card on a signal strength as weak as -79 so -58 is a good clear 
signal.

I am using an Alfa AWUS036NH  I have no problem associating with the AP, it 
happens almost instantly.

I am using BT5.1 with the latest drivers and Reaver 1.4

Thank you and I hope you can help.

I'm running reaver 1.4 on BT5-r1 with an rtl8187L chipset (same as AWUS036H).
I experienced the same problem, I have:
[!] WPS transaction failed (code: 0x02), re-trying last pin
...some retries
[!] WPS transaction failed (code: 0x03), re-trying last pin
..some retries
[!] WPS transaction failed (code: 0x04), re-trying last pin
...some retries
then:
[!] WARNING: 10 failed connections in a row

but after waiting a while the attack resumes automatically without problems.

The only question is, what does code 0x02, 0x03 and 0x04 means?
Just to understand what is really happening.

#wps transaction failed (code: 0x02), re-trying last pin
#wps transaction failed (code: 0x03), re-trying last pin

I've experienced the same issues using an Alfa rtl8187. I've found the solution 
to the problem is to play with the "-d" flag.

Start at "-d 15" or higher until you stop receiving the (code: 0x02) (code: 
0x03) errors. Then work your way down. Each router I've tested likes a 
different value. 

I was also using the "--no-nacks" argument.

I have same issues & playing with flags including "--no-nacks" "-d 15" even "-d 
30" "-w" but no matter what eventually a hard reset of the router is needed and 
I can continue with the attack... Same Alfa rtl8187 AP is a Netgear WNR1000. If 
you found a resolution for this issue please keep us posted! Thanks !

I'm using ALfa rtl8187. reaver 1.4

found this way to make it work

1. run: aireplay-ng mon0 -1 120 -a 68:7F:74:E2:4A:1C -e kitty-Home
2. then: reaver -i mon0 -A -b 68:7F:74:E2:4A:1C -c 6 -vv --no-nacks --win7

hope this help ;)

I am using Alfa rtl 8187 , reaver 1.4
I can confirm that it works with the above commands with AP ranges between -69 
-75, a bit slow but it works.

Do a wash -i monYOUR and see if the adapter didnt go (null). This happened to 
me on a dlink AP and 2 weeks after its still (null). Must have re-seted it or 
something, but wash shows it up as (null) instead of no as it was in the 
beginning. Try another AP and see what you get. If its not (null) try the -d 
function, start with 15 and if you still get timeouts, put it higher. I've had 
good results with the -d function (delay) if still u dont get anyting, reboot, 
reset, and try again. This sometimes works for me in native BT5r1 release hd 
install.

I've had success with reaver-wps delaysof 15+, while performing fake
authentications via aireplay-ng.   Some APs are more picky than others.
Try aireplay with 1300-6000 intervals, keep alives (-q) at 10.

Haven't seen any changes to svn... is this project dead?

Hi guys, i have been facing this problem as well, however i saw something that 
might be interesting.

1) I associate to the AP using airodump 
     aireplay-ng mon0 -1 120 -a 00:30:4F:XX:XX:XX -e XXXXXX -q1

2)   After it was successful i tried the reaver attack
  reaver -i mon0 -A -b 00:30:4F:XX:XX:XX - c 6 -d 10 -vv --no-nacks --win7

What is shown in the airodump-ng is that every time i am trying a WPS PIN with 
reaver, the router immediately disassociates A)  and reaver gets a time out and 
tries the same pin. B)

A) ----airodump----

So it looks that the Router might be in lock down mode or it has some kind of 
mechanism that  blacklisting my  Wifi card.  Im changing the MAC now and will 
try when the Lock down is down (probably about 5 minutes).

You might want to try to see if it happens the same.

If i let the reaver continue it will crack it? or something wrong ?
& why am not getting the M5/M7 ??

I try before another card Ralink RT2870/3070 (rt2800usb) same results as i get

All,

I have experienced the same/similar issue.  I was unable to get passed 0.00% 
complete on  3 different routers that I tried.  At first I thought this was due 
to my 2800usb driver for my Alfa card (some forums claimed), however this was 
not the case in my tests.  I feel that routers have gotten more aware of WPS 
exploits and will literally deny your pin transaction immediately due to rapid 
attempts.  This is what worked for me in Reaver

 reaver -i mon0 -b xx:xx:xx:xx:xx:xx -S -N -L -d 1 -r 5:3 -vv  

-d was used for seconds delayed in-between each attempt and -r 5:3 was after 5 
attempts wait 3 seconds.  This will need to be adjusted to whatever the router 
can handle.  I found that through out 1 session, I had to adjust these delays 3 
different times.  You will know it needs to be adjusted when you get 
several/back-to-back failed attempts.  Please provide feedback if this helped 
anyone!

AWUS036NH was the adapter being used

when i get these i run this and it seems to fix it for a bit:

airmon-ng stop wlan0

airmon-ng mon0

reaver -imonX -vv -a -b<mac> -x180 -L -n --nack

these errors still pop up but mostly when im seeing signal drop from the AP.

Hello all.
And thank you for your answers .. but i have a question it is why am NOT 
getting the M5,M7 ... the signal of the router im trying to crack is 70-75 is 
it Normal or what? im running reaver all night and yet it still 12% ... my 
speed is (20 seconds/pin) ? and one more question that i have been thinking of 
it all night .. ?? if i get the full progress of reaver .. i mean the 100% ? 
then i will crack the password 100% ?? or i might not crack it .. ???

Thank you :)

Thanks for all the info in here. I have made progress!

I am having the same issues posted here. I hope someone can get some progress 
with what i have found.

I have tried several AP's and i get locked out after about 4 pin attempts. 
After about 5 minutes it will let me try once or twice more. Then im locked out 
again.

I have found another AP that dose not lock me out but i still get the 0x03 
error along with WARNING: Revived timeout occurred every couple pin attempts.

EDIT: i fixed "WARNING: Revived timeout occurred" by using -vv -d 5 BUT i still 
have the 0x03 error every few pin attempts.

what i gather from reading forms is that the 0x03 error is from being farther 
away from the target AP that desired. 

so i assume there are older AP's that wont lock you out. 
Is there a way around the lock out feature on the new AP's? Possibly spoofing a 
MAC of an already connected device on the AP?

any help would be appreciated. Im new here. :)

Thanks in advance!

Hello All,

This is my first post.  I have had trouble getting Reaver 1.4 BT5r to work as 
well.  Was getting all sorts of time outs and failed transactions.  I am not at 
my own computer therefore I cannot post a screen dump of the Reaver output at 
this time.  I tried the basic argument and got terrible results.  Would try 
same pin over & over.  After searching forums I began trying the options 
provided with Reaver.  I used aireplay-ng to associate and ran airodump-ng and 
wash in the background. Used rt2870 with 2800usb driver against Netgear AP.

 arguments:

reaver -i mon0 -c [ap channel] -A -b [bssid] -vv -N -w -t 5 -L -x -d 0 -r 5:3 -S

aireplay-ng mon0 -1 120 -a [bssid] -e [essid] -q 5

I varied the -t, -d, -r values throughout the run with little change in speed.
On the sixth day I woke up & checked the progress and to my surprise there it 
was!!  The PIN and the passphrase and they worked!! 

Hope this helps someone...  If anyone has any tips how to cut some time off the 
six days, please post!!

I FOUND THE PROBLEM!!! = Distance!!! Basicly reaver tries the same code over 
and over because it did not receive back the signal that says the code didnt 
work so that it can try a new one that's basicly it( and of course after u did 
command - airmon-ng check kill)when i try using a reaver on a AP thats directly 
in my bros bedroom it works(appx 7 meters away) So now im looking for a 
stronger wifi adapter

Nothing is a 100% sure in this world try what i did to resolve it for me i hope 
this helps!

Ok...I have literally tried everything and I think I am close.  I finally have 
it tuned enough to hit 6% without issue...and then all hell breaks loose.  All 
I get is warning: failed to associate with <mac> <essid>.  Im at mon4 by now 
with the airmon-ng, I have reassociated over and over and have adjusted 
argument a billion times over.  Why will it associate in aireplay and then fail 
to associate for 6 hours or more straight?

i had the same issue and solved it with a directional antenna and the 
--no-nacks command, if the pwr is > 55 it speeds up the process and deletes the 
errors

I have noticed that when I got this problem, the error shows after reaver 
reaches 90%. Before 90% it works fine. I couldn't find solution.

I tried 
1. run: aireplay-ng mon0 -1 120 -a 68:7F:74:E2:4A:1C -e kitty-Home
2. then: reaver -i mon0 -A -b 68:7F:74:E2:4A:1C -c 6 -vv --no-nacks --win7

and resolved the problem 
thnx to itmanvn
