Raise maximum connection limit for Internet Sharing? I’m using Internet Sharing (USB 10/100/1000 LAN &rarr; Wi-Fi) to give a tech demo of a web site, running locally on my machine, to multiple phones.

I want to connect 15 phones to the shared network, but upon connecting the 6th phone, the phone reported “Access point temporarily full”.

Is there a way to configure how many devices can connect to Internet Sharing? I’m fine with delving into the Terminal.
The limit seems to be hard-coded into macOS and cannot be modified by setting properties or similar. 

However, if it is an option to use additional hardware, you may put a router in between. That way, only the router would connect via Internet sharing, while the other devices would connect to the router.
