Okay so I don't know what the issue is. I'm about to have a mental breakdown. I own both an iMac and a MacBook Air. On both machines (but the iMac more often) I'm having issues with certain websites. Pictures are broken, and I keep getting "server cannot be found" pages. Which are sometimes fixed by turning wifi off and then on again. This all came out of the blue, and I have NO idea what could be causing it. It's driving me crazy. Any help would be greatly appreciated.
