Router + wi-fi + linux with its own software for a public access point. Is there a ready solution?

Question

linux

You need to build a demo prototype of a public wi-fi point with your additional software on linux (captive portal + big brother).
The solution should be as cheap as possible, preferably from the secondary market and without a month of delivery from Aliexpress.

Answer 1

If public WiFi is planned in the Russian Federation, then do not forget that anonymous access is prohibited. You can look at the list of available equipment from a company that will help connect your network with the laws of the Russian Federation. They have their own software for guest authorization.
