[X4U] How can…?

[Winston MacKelvie]

Can someone explain how, an iPhone, iPad and MacBook Pro can all show strong signal connection to my nearby iMac that has a good (DSL) internet connection, yet they all cannot load certain web pages (i.e. Apple.com)! while other pages load as expected? 

I've reset Safari, rebooted all devices, cleared Safari caches, changed network locations, deleted and created new networks, and still the problem persists. 

I have had successful WiFi connections to all these three devices in the past all from the same iMac PPoE provider. 

The iMac loads all pages flawlessly.

Thanks listers,


Winston
