I moved recently and yesterday got internet installed at the new house, and now most sites and yahoo and aim are not connecting. I can get gmail, this site, sometimes craigslist, msn messenger, skype, and nothing else. No settings have been changed, the only thing new is the new internet. My roommate can access all sites just fine on HIS laptop, so its not a provider issue, its my laptop. Whats going on and how can I fix it?
