We've never done the dish except for tv and if the wind blew, we lost the signal.
We have the wireless router attached to the modem for my computer, but since I have the newer computer, it's quite quick.
I think the biggest problem with M's computer is that he prefers AOL, because he's too lazy to learn anything else, and wants it to go straight to AOL when he turns it on. It goes from IE/MSN to AOL and he wonders why it takes so long to load. When I use it on MSN or Firefox, it's fine.
