Hi, I've just made the switch from PC to Mac, and I'm getting really frustrated. Up until tonight, internet was working perfectly... I have no idea what changed, but now it drops out continually, and I bumble my way throught the Network Assistant until it comes back on. And incidentally, the network assitant tells me it couldn't connect, even though the status for the airport says otherwise (and I can browse). It works fine for a while and then is unbelievably slow..... any advice would be so greatly appreciated, and I hope I'm explaining myself well enough! Thanks, Andi.
