WiFi issues on OSX Mojave

gistfile1.txt

# some solutions
1.- Disconnect external SSD drives, USBs, _ANY_ stuff that requires power

2.- Turn ip6 off
Check what are the services:
networksetup -listnetworkserviceorder
Then run:
networksetup -setv6off Wi-Fi 

3.- Activity Monitor - search DNS, kill processes
(NOTE: THIS FIX SEEMS TO BE TEMPORARY, THE IP6 thing works better IMO)

still not working?
4.- From the OS X Finder, hit Command+Shift+G and enter the following path:
/Library/Preferences/SystemConfiguration/
5.- Within this folder locate and select the following files:
    com.apple.airport.preferences.plist
    com.apple.network.identification.plist
    com.apple.wifi.message-tracer.plist

    NetworkInterfaces.plist

    preferences.plist
6.-Move all of these files into a folder on your Desktop called ‘wifi backups’ or something similar – we’re backing these up just in case you break something but if you regularly backup your Mac you can just delete the files instead since you could restore from Time Machine if need be
5.-Reboot the Mac
6.-Turn ON WI-Fi from the wireless network menu again
