How to add an encrypted WEP to Airport network
My husband must use his old flowerpot iMac for the OS 9 needed to run Claris Homepage (he's memory challenged now and can't learn a new authoring program). Everything else in our home is on WPA2, so we made a Guest with no encryption. We've just discovered that a neighbor who terrorizes our neighborhood and whom we don't know (he's the only one near enough) is using the Guest. Given our lack of a relationship we'd feel better is we could encrypt with the WEP the flowerpot uses. This Apple Support page below seems to indicate we can, and yet I can't make sense of it. Could someone translate it to simpler terms? I'm very comfortable tweaking Airport Utility configurations, I just don't get this.
