How to reset Mac Network

Close any apps that use the network.
Such as turn off Wifi, unplug network cable, bluetooth.

Click the Finder icon. It’s the two-toned smiling Mac logo in the Dock, which is usually at the bottom of the screen.

Press ⌘ Command+⇧ Shift+G. This opens the Go To Folder window.


Type or paste /Library/Preferences/SystemConfiguration/ into the blank.

Click Go. This opens a list of System Configuration files.

Select all of the network-related files in the folder. Here’s how:
Press and hold the ⌘ Command key.
Click all of the following files (while continuing to hold ⌘ Command):
com.apple.airport.preferences.plist
com.apple.network.eapolclient.configuration.plist
com.apple.wifi.message-tracer.plist
NetworkInterfaces.plist
preferences.plist
All selected files should now be highlighted in blue.

Delete those files.

Restart your Mac.
