My internet connection works because I'm using my WiFI on both my iPhone and iPad, it's just the browsers that aren't responding. Also, it works fine on my girlfriend's MBP running Lion. Oddly enough, apps that use the Internet connection e.g. Twitter are working normally. I use Safari primarily but tested to see if it worked in Chrome and Firefox but no success. Also tried restarting the laptop several times, troubleshooting etc. It just started out of the blue last night, it worked before that perfectly. I'm on a base 13" Macbook Air running Lion. Anyone know what else I could try? Thanks!
