Hi, I have an ibook that is connecting wirelessly to my Belkin Wireless Router. The router is hooked up to a PC with an ethernet cable and the ibook is wireless. I want to secure the connection so nobody can steal the signal, etc. When I hook into Belkins online config and set up a WEP and I select a password......the ibook won't connect. How can I secure this connection so both computers are secure? Thanks!
