I have an original UMB, and for some reason the internet is stupid slow on it. I have a Dell, but love using my Macbook so much more. My roommates are also on PC's, and don't seem to have the problem. It's everything from pages taking an unnecessarily long time to load, Facebook/FB Chat is almost impossible to use because it will time me out, or just not load pages. It will be fine sometimes, then randomly cut out and be terrible again. It won't load videos on YouTube etc. I don't understand what could be the problem. I would say the internet, but everyone else's is fine? I'm using FireFox on 10.6.2.
