What does not work is changing various metrics on the route or deleting re-adding routes:
sudo route change 0.0.0.0/0 172.17.2.1 -hopcount=4Also it does not work to change metrics on the interface:
sudo ifconfig en4 metric 13What does work is reordering your network services.
View current order:
networksetup -listnetworkserviceorderSet a new order:
sudo networksetup -ordernetworkservices "Wi-Fi" "MiFi 7730L" "Bluetooth PAN"Verify the interface being used for default routes has successfully changed!:
route get 8.8.8.8
