How do I enter the settings of my router from the mac terminal?

Depends on the router, some use the Telnet protocol, others use SSH, if you use telnet you can install it using brew link , if it's ssh you can use the native ssh command like this: usuario@ip .

Remember to validate that your router supports these types of connections, for this you can do it in three ways:

• Reading the official manual
• Searching for the option to enable shell access from the WEB Dashboard
• Performing a port scan

If you want to perform port scanning you must use nmap, for this you can install it using brew brew install nmap and then executing nmap -A -T4 ip-rouer , after this you will see the open ports next to their connection protocols, depending on the case it will be the way you can manage your router.
