I am newer to Mac by about 7 months, don't really have an issue, except for my wireless. I seem to lose and reconnect to my wireless router, only with the Mac, I have a desktop, and the wireless router is sitting next to the Mac. I can be using it, and the connection will be lost, when I look at the wireless indicator, it shows it is searching, it will reconnect, but why do I lose the connection. I have the wireless router connecting my work Pc and my ps3 without issue... Any idea's? thanks. Dennis
