it's the oddest thing. I can't connect to certain wifi networks on it mac while my iPod touch can. I can connect, just pages won't load on my MacBook but will on my iPod touch. Right now I'm connecting on this iPod touch via wifi connection called d link. But my currently opened mac won't load pages or retrieve mail. The very same situation occurs when I take both my mac and itouch toy friends house and try to connect to his wifi network.
