you can easily crack a corporate network you need more number of iv packets to crack those stuff the home network will barely generate the required level cause there are not many number of users there...i myself tried to crack my own connection but was unable to do . however i have cracked CCD wifi which was useing WEP . WEP is very very easy even 12 year old can do it .
but 128/256 bit encryption are really hard to crack .hoping Cell Could be used for this
