Hello. I was given and old 2007 iMac 20inch, Core2Duo. It runs OS X 10.4.11. I'd only use it for watching YouTube at breakfast. If I could have AirPort Extreme to work. It sees all networks including my 2.4 and 5 ghz. First, didn't recognize the password, then did but can't keep the connexion alive. Runs through 2.4 and 5 ghz and then dies. Its there something I'm doing wrong or I'm not doing at all? If I can have it to work, the little guy goes to recycling. what else to do with it? Thanks for cues and tricks.
