I have an iMac, about 4 months old. Running OS X 10.6.2 . I connect through the internet through a cable modem, not wirelessly. This morning, I couldn't get a webpage to load so I rebooted the computer. started working but after about 3 clicks in to pages, it quit. Mail worked for that time and now it won't connect as well. If I unplug the internet cable, it works again for about the same amount of time ( 3 minutes, 3 clicks on pages). I'm on the internet now through a PC off the same router so that can't be the issue. Any suggestions?
