I am trying to use h1kari's reinj tool to reinject SYN and ARP packets
back on to a WEPd network.  Has anyone played around with this tool?  I
am running Open BSD 3.2 with a SMC2632W v.1 (firmware 7.6).  In h1kari's
instructions, he says to put the WiFi card in injection mode by typing:
$ sudo wicontrol wi0 -p 5 -f 7                 (the -f 7 makes the card
listen on Channel 7)
 
Once the card in injection mode, you are supposed to fire up the reinj
tool which will scan for arp and or syn packets.
 
$ sudo reinj wi0 00:34:87:53:db:fa 1000000 2
 
Once reinj finds an arp packet, the tool is supposed to display a
message that the packet will be reinjected in the network.
 
My problem is that I don't believe that my SMC2632W is catching any
network packets when it is in injection mode.  I can run prism2dump and
will not see any valid packets that I know I am sending.  I only see the
beacon packets.  However, when I put the card into monitor mode
(prism2ctl wi0 -m), I can then run prism2dump and see all the packets
that I am supposed to.  I am trying to figure out how to put the card
into injection mode and still capture all packets.  
 
Any help would be much appreciated.  Thank you in advance.
