Hello. All of the sudden I have a problem with my internet access with Safari, internet-based widgets, iTunes and other Apple-based software. Firefox, Mail and Skype work fine, but absolutely no access from the above programs. From what I understand, it has to do with proxy settings. I have gone into my system prefs -> network -> Advanced and cannot see anything there (there should be no proxy settings). I checked and un-checked "Passive FTP Mode" to no avail. This just happened out of the blue! Help?
