Why can't I connect to WiFi distributed from linux?

Question

linux

I distributed WiFi from a laptop (kali Linux), I'm trying to connect from an android. I select the desired network in the menu, the phone writes "network saved" and nothing else happens.
I saw an article on the Internet with a similar problem, it is proposed to check the following settings on the router.

But what if I have Linux instead of a router?

Answer 1

Default route, dhcp configured?
