My apologies listers. I neglected to change the Message . This was meant to be a new thread. My earlier listed MBPro problem of certain web pages (i.e. Apple) not loading has now another dimension. Some pages will start to load then stop. If I click WiFi OFF (menu item), the page finishes loading in a instant! Next page same thing. All pages load properly from the iMac with the WiFi network. Can I find (where?) and trash the iMac network prefs? Could that even be the problem? Winston
