Is there an interface named wlp3s4?

ip link show

If it exists, does it already have something controlling it?

ip addr show

Is the radio blocked? Look through dmesg output.

Thank Dan!
it's very strange, i'm unable reproduce problem nowi think i install from debian-11.0.0-amd64-netinst.iso 
but it's really installed from MATE live CD??USB installer stick isn't properly prepared??when i copy *-netinst.iso to /dev/sdb, it's done very very quickly

usually i can set up network with ifup after installation from *-netinst.iso     
but some network manager in MATE might cause trouble when i run ifup?
