So just got brand new iMac. It's great of course... only problem is.. I can't get it online on the wireless. I figured it's the same reason i haven't been able to get the wireless on my Itouch to work. A few months ago, we got a new Router, a Trendnet TEW-636GR and we had a guy from some computerhelp business install. But he musta' set up some kind of firewall or something, since it's only the macbook i'm writing this on now, and my moms pc that connects. anything else we need to connect it to a regular internet cable. I figured out how to acces the web-based setup for the router, but have no idea what to do next. Help?
