If you want to set up an internet or network and find your Macintosh computer’s default gateway, here is how to do so.
You have to setup Default Gateway for you Mac….
Step 01: Go to Preferences, Apple Menu at Top Left > System Preferences
Step 02: Click on Network
Step 03: Click on your preferred network name; the numbers mentioned in front of the word Router are your Default Gateway
Apple refers to ‘Router’ as/for ‘Default Gateway.’
I hope it helps…
Thanks & Regards
