ok well i have been doing some reading on this and i think i am pretty much good for the rest of the steps but what i cant figure out is actually the critical step. i know how to get the packets and get info out of them but what i dont know is how to make the initial connection lets say to a wireless router. if i am connected i can gather them and get the info but i need that initial connection do i not?

Know what you can do.
You can only get that connection if you have cracked the WEP or WPA key. To get the WEP key you will need about 250000 Packets -> 1000000 Packets depending on the password strength. eg 128bit, 256 bit, or 64bit... Then you can use that password and connect so that you have free internet and so that you can add your MAC on the router for future use... If you want... what are you using to get the password?

You will need to get Airdecap, you only have the .cap files so you need Airdecap to decrypt those capture files...

Read up more about it at that link. I have a aircrack and airdecap and a airodump for windows if you want? Very easy user interface. Cain and Abel can also do that but I am not sure how as I don't use Cain for that purpose, Ethereal might help you with that too.

Yea...decently experienced user in other regards but total noob when it comes to WEP cracking. I've got a wep key. Now what do I do? Plugging it into the "password" bar of a network results in a connection error. What do I do now?

you need to decrypt the .cap file containing the encrypted WEP key using decap or Cain & Abel, or you can crack the key using Cain & Abel.
