Hey. I have also encountered the problem of not being able to connect. I have tried a bunch of the command prompts and it says the commands are incorrect or not recognized. I have turned off my firewalls and whatnots and still can't seem to connect to a network. When I try to an error message shows up in the log saying..
Winsock error 10013: The requested address is a broadcast address, but flag is not set. I don't know if i am doing something wrong or if it just won't work. Oh and by the way i am using windows vista if that makes any difference
