 All researched libraries have method [`scanNetworks()`](https://www.arduino.cc/reference/en/libraries/wifi/wifi.scannetworks/) defined by the first WiFi library.
 
-To get the result of networks scan, all libraries have methods defined by the first WiFi library: `SSID(n)`, `encryptionType(n)` and `RSSI(n)`. Additionally all libraries except of the old WiFi library have `channel(n)`.
-
-Enumeration of encryption type constant names for`encryptionType(n)` are in esp32 and Portenta C33 very different from the common set used in WiFi, WiFi101, WiFiNINA, WiFiS3, esp8266 and WiFiEspAT.

-All libraries except of the old WiFi library have [BSSID](https://www.arduino.cc/reference/en/libraries/wifinina/wifi.bssid/). WiFi, WiFi101 and WiFiNINA return reversed ordering of bytes.
