Wifi and networking

Hey there! I have some problems with WiFi and the connection network.

e/OS has a Private DNS option in Network and Internet, usually I have Quad9 DNS active either for WiFi or SIM carrier data but lately I’ve been having a lot of problems with the speed and the connection as well. Several offline states connection have been appeared. So I would like to know how the Private DNS its structured to look for a solution.

  1. Do Quad9 DNS settings has DNS1-2 and which one has e/OS include in this presetting?
  2. Automatic DNS do has any preferences rules for connection? Or do connect randomly with the first option available? ( for example, my data carrier phone is Moviestar, so default DNS is Telefonica’s DNS but I’d rather prefer to have some better actor in the middle as 9.9.9.11)
  3. For WiFi connection, where we can select static IP settings, do we have, as users of e/OS, to change as well the configuration of a WiFi network for a much better performance even with Private DNS in Quad9 mode?

I’m asking this because I’ve already tried these configuration to avoid offline status or discontinued connection:

  1. Private DNS in Quad9 with default DCHP settings ( Disconnected or offline status sometimes appears)
  2. Private DNS in Quad9 with static IP and Quad9 settings ( like 9.9.9.11/149.112.112.11) ( still has offline status or even no connection at all)
  3. With Automatic DNS seems to works, but after airplane mode use need to restart the phone to received any kind of signal.

I also wonder if Murena would like to introduce inside Private DNS the option of tje Cloudfares DNS as well.
