I have a Macbook Pro that was running OSX Tiger and recently switched to Snow Leopard. I'm using an Airport Express and it would work fine with Tiger. Ever since I installed Snow Leopard, my Internet is really slow to load or it won't load at all. My computer picks up the connection and my iPhone still connects just fine. If my Internet doesn't load, it'll say that the server cannot be found, but when I run network diagnostics, it says my Internet is working fine. Is there anyone familiar with this issue? I can't find a solid solution to this.
