Question: Can't refresh wifi after upgrading to high Sierra

Before upgrading to High Sierra, I was able to refresh the wifi connection by clicking on the wifi icon on the toolbar, then "Open Network Preferences", then there would a pop-up for diagnostics and this is not available in the High Sierra system. Please help as this is a very useful utility for me given my problematic connection.

MacBook Pro TouchBar and Touch ID, OS High Sierra

Good afternoon mtbdwk,

Welcome to the Apple Support Communities!

I understand you are looking for the Wireless Diagnostics in macOS High Sierra. Press the Option key then click on the Wi-Fi status icon on right side of the Menu bar on your MacBook Pro. The resource below will provide some wireless network troubleshooting steps.
Check for Wi-Fi issues using your Mac
Take care.
