Hi, I have shared my iMac's (white 24") internet connection via Airtport, because I would like to use internet with my MacBook. The Problem is that it's not working like it should, evertyhing was fine when both machines ran on Tiger. Now both has Leopard and my MacBook just don't want to stay connected. When I boot my MacBook. Everything is working like it should but suddenly it just drops the connection and only reboot helps. MacBook's status bar still shows that I'm connected to the network and it has full signal but when I open the web browser, it says I'm not connected... What a hell could be wrong?
