I have a SR macbook and i have had a host of problems getting on the internet. I can connect to my network but i can't stay on for more than a few minutes without it stop uploading pages. it just stops. But when i check my connection it shows that it is working properly. I called DSL several times and they had me change all sorts of settings onthe modem trying to get it to work properly, but no luck. My freind came over with his macbook and he was able to surf just fine. We did side by side comparisons loading the same websites and his mac did fine while mine stalled out evertime. I came to the conclusion it was my mac and not my network. seems like a logical choice.
