So in the last month at school i cant connect to the internet. I can connect perfectly to the router but when trying to load internet in safari, firefox, or opera, it wont let me. The kids next to me on either side connect perfectly fine with their macs. I have a 2.16 ghz Macbook black, Recently installed parallels software, along with windows xp, for schoolwork. I also have internet shareing through the ethernet port for my xbox live, but i also tryed to disable that and it still did not connect. i also deleted, -library/prefences/com.airport file to try to reset back to default. Anyone else know what it can be, or what i need to adjust, or anything on the subject?
