My own secure DNS server - Pi-hole on NanoPi NEO3

I care about my own information security and I don't want to put up with such flow of ads.

The first and the simplest step of the fight is AdBlock plugin in the browser.

Ths second step is custom hosts file. In this manner you may protect a few PCs, but it is difficult to cover each device in your network. Also, large hosts file can affect performance.

The third step is your own DNS server that will filter all requests from each device. The solution is Pi-hole.

As a platform for the Pi-hole I choosed a small device NanoPi NEO3 with 4 ARM cores (Cortex-A53 up to 1.3GHz) and 1 GB RAM (DDR4) on Ubuntu Core 18.

MacBook Air Recovery ask WPA2 enterprise credentials when connecting to WiFi

The problem.

My MacBook Air (13-inch, Mid 2013) with macOS Catalina (10.15.5) in recovery mode runs on OS X Mountain Lion (10.8).

When I try to connect to WiFi instead of ask a single password it ask me login and password (The WiFi network requires WPA2 enterprise credentials). But I don't use WPA-Enterprise.
