WiFi fails to connect

Currently using


Beta 17C79a


WiFi shows as connected, however webpages, remote locations etc will not load


WiFi appears to be enabled, and selectable

However you are unable to connect to the internet

I have deleted the WiFi connection, added again, renamed it, changed password etc, and the iMac still refuses to connect using WiFi - have to resort to Wired Ethernet


This has been happening for some time and has been reported using Feedback Assistant


All other non High Sierra Laptops along with iPads/iPhones (using iOS11) connect with no issues
