Orange Pi Zero Plus Wifi connection lost

Orange Pi Zero Plus | 5.83 | arm64 | aarch64 | 4.19.38-sunxi64

Hello Armbian community,

I set up the wifi with armbian-config, but  Wifi connection get lost or after reboot it does not connect again.

Is there something I could to.

would it help to turn off power management ? how too?

looks like i am not the first with this problem:

But if its possible I do not want to turn off the network manager

And it looks I have also a problem with the character set, i noticed this on OPI Win and on the Zero +.

when I make the first update after Installation, I am asked too choose the character set.

I am from Austria, therefore I choose "Latin central europa" and even with guess the optimal character set", I have a strange behavior on ssh connection.

mostly from copy and paste from the Browser

is this "feature" know or do I something wrong?

greetings and thanks again

looks like
