My MBP actually kills my Internet connection when it's using wifi. Practically only when using Safari 4 (which is the slowest browser I've ever seen - others say it's fast, but I've reinstalled multiple times and it's still mud). I use a 2Wire router (everyone says 2Wire suxxx), but when I lose the connection, our desktop with an Ethernet connection also goes down.

When I use Chrome beta or Firefox it rarely ever happens.

I'm more concerned with why Safari 4 runs like a turtle in cement shoes through a tar pit.
