Cracking a decently generated WEP key (in other words so that WEPAttack or other dictionary based crackers won't work) takes so long as to be counter productive. Ask around. Other than folks that have cracked their own WEP key there are very few people that have successfully cracked a WEP key. It just takes too long and there are other, easier ways to attack a network. We have discussed this repeatedly on this forum so I am not going to rehash it all here, but when you are doing a full penetration test (read: not just the WLAN) it makes more sense to attack something other than the WLAN first. You will find a much higher, quicker success.
Will all respect. You seem to have no idea of what you are talking about.
It is possible to crack a 64 or 128 bit key in less than 30 seconds with enough packets. It is also possible to use statistical methods to crack the key even with patched firmware cards. And it is also possible to generate traffic on the wlan (without knowing the key) to gather enough packets to launch a sucesfull statistical based attack and recover the key.
And, many enterprises have their wlan directly connected to the lan, thus if you manage to crack the wep, you have bypassed their perimetral security (firewall). Sometimes (depending on the mode on which the AP is set) it is possible to launch an arp-poisson based sniffing from the wlan to get the traffic on the internal LAN, making password sniffing, connection hijacking, identify spoofing, and of course accessing many servers and services that can only be accessed from inside.
If you still think that there are only few people who have cracked WEP encryption, you should seek for the right tools to do it.
And finally, talking about security is legal. We are not talking about entering other's network, but talking about the security of the WEP encryption algorithm for wireless networks. But... perhaps, as Matrix said,... "en la ignorancia se encuentra la felicidad"...
