[X4U] video surveillance/webcams on the Mac

[Winston MacKelvie]

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?
