Where have Network Diagnostics gone?
Before I upgraded to High Sierra when I was having problems connecting to websites there was a Diagnostics button in System Preferences/Network that allowed me to check if the connections to my ISP and the Internet were working OK. Sometimes I found that the ISP connection was OK but there was a problem with my ISP's connection to the Internet.
Now that I'm running High Sierra there is no Diagnostics button. Has it been removed or does it appear somewhere else?
iMac, macOS High Sierra (10.13.1), iPad Air 2, iPhone 7 +
