basically Wifi is like a two way radio that boradcasts at a diameter of 100 feet ( this is without signal replicators, or modded antenas). if you go within range your antena picks up the signal and different situations can occur.
because of the wide spread of these network 2 new things have come about. 1 is wardriving wich are people driving around and finding and recording the location of WANs and another called Warchalking which is the same concept exept you actually write down on the sidewalk in front of the WAN. they use symbols that give useful information on how to use the network
everything is pretty much self explanetory you put the SSID of the network the bandwidth and if its a WEP you just put the person you need to contact to get in (via Email)
so here is how you connect to each type.
open: you go within range with a computer that has a card capable of picking up the same frequency (802.11a,b, or g) this isnt anyhting to be rpoud of even a retarded monkey can do this
closed: you need to bruteforce, or dictionairy search for the password and with the encryption technology most of these routers use it could take anywhere from 5 seconds to 3 weeks. so good luck.
WEP (Wired Equivalent Privacy): for this you can either do the same as for a closed connection or contact the person. WEP means that the person is willing to share the connection (sometimes they might charge) WEP is what Starbucks, Mcdonalds and other buisnesses use.
hope this helps. I got out of Hacking before Wifi hit so I dont really do it but if anyone has any questions on any of these I would be glad to answer any question
