Are you using the ipwraw driver?

ie:
#modprobe -r iwl3945 (replace with your driver)
#modprobe ipwraw

some cards are not capable of injection...

tutorial i had posted once upon a time, gives the general idea...

Remember its not "cracking" its testing wep. :)

Disclaimer:  All instructions are intended for security auditing or educational purposes only!!  Should never be used for cracking a network you do not have permission to test. (I got banned from yahoo groups for a post similar to this; why I use google now:)

WPA psk (typically wrongly known as tkip) is somewhat crackable with dictionary / brute force.  Like any brute force, if there using a English word, it will only take minutes.  Otherwise...  You need to generate a rainbow table, etc, etc...  

WPA AES is completely untouchable at this point...

Basically same idea, authenticate with base station / access point:

Then

download a word list
http://ftp.se.kde.org/pub/security/tools/net/Openwall/wordlists/ 

generate word list
# zcat all.gz | egrep -v '^#' > dictionary

Start aircrack
# aircrack-ng -w dictonary -0 wpaout.cap

Opening wpaout.cap
Read 15683 packets.

   #  BSSID              ESSID                     Encryption

   1  00:A1:B0:30:5C:84  HOGE                      WPA (1 handshake)

Index number of target network ? 1

Also chop, chop attack...  which is fairly useless...  more of a proof of concept.

First needs to be PSK / TKIP, QOS needs to be on, then you can run chop chop...  

All you can do is inject arp packets, syns, dns, other small stuff...
