Hi, I am running Leopard 10.5.1 on my MacBook and ever since I installed it (as soon as it came out) my internet connection keeps dropping. It did not do this with Tiger. I know there's nothing wrong with my internet connection/router because my MacBook will stop dropping the connection as soon as I plug it into its MagSafe connector. I've tried booting up in Safe Mode and no joy. It gets really annoying because on things like MSN it keeps loggig in and out because of the connection. Safari repeatedly gives me the you are not connected to the internet warning. But plug it in and it's fine. Is there a fix for this? Anyone else having the same problem? Is it likely to be fixed in 10.5.2? Thanks.
