Select your ethernet/wlan(wifi) network at the top
Then randomize the mac address, make sure it starts with 02 if its wireless (wlan/wifi),
you can just tick these 3 boxes
After changing that disable all the networks u arent using, but dont touch the kernel ones with only 0's as the mac, you can disable them by unticking the boxes at the top
Restart your pc and check that mac stays changed and the other networks stay disabled
