If you use a proxy server, enter its address, otherwise (and it's most likely otherwise) don't enter any proxy server address. (Home internet connections don't use internet proxy servers, and most domain networks don't any more.) The username and password won't be needed either, since you won't be using any proxy server. (Make sure you're connecting to YOUR wireless signal, not a neighbor's signal. Not only is that illegal, if the signal is secured, you won't get an internet connection, just a wireless connection. ';Access'; means that you're paying for internet service, either directly or as, say, part of the tuition if this is a school connection. Having your neighbor's permission to use ';his'; connection is illegal, because he doesn't have the legal right to give you permission - only the internet provider does - it's *their* connection.)
