Problem in reaver

[maxyoshida]

Hi, I use backtrack 5 R2, My system is fully updated, I tried to crack a wpa by using reaver but I got 2 problems with this:
1) It is very slow
2) When cracking reaches 40-50% it starts to even slow more, like cracking 0.01% every 16 seconds instead of 0.05% every 16 seconds, after some time cracking hangs up and doesn't move (sticks on a number like 60%)
Is it possible to solve these problems?
Can I speed up cracking by using more hardware? (I can use up to 4 laptops & 7 Alfa networks at same time if this will speed up cracking)
By the way if there is any solution please help me (If this costs money like buying hardware or software it will be ok with me no matter how much its costs)
Thanks in advance.

**No matter what it costs**
Its nothing to do with CPU hardware, its all about good strong signal to your router. Go closer to it and try using other Reaver options (commands) check them in the official Readme here: http://code.google.com/p/reaver-wps/wiki/README

Try to see if your using the latest updated version, trunk 113 i think:
svn checkout http://reaver-wps.googlecode.com/svn/trunk/ reaver
and the
./configure && make && make install

I am led to believe a lot of it is also dependant on the AP resources, which of course you cant control.
