Thanks for your help!

And after looking for solutions i found this command, also add at the end of /etc/ssh/sshd_config:
IPQoS cs0 cs0
doing this: OpenSSH sets the TOS (type Of Service) field in the IP datagram as “lowdelay” for interactive sessions and “throughput” for non-interactive sessions. My router doesn’t handle properly those settings, so I changed them in Cs0, Cs0 (aka 0x00, 0x00) (best effort, best effort) and solved the instability/freeze SSH issues.

Thnx and have a nice day! 🙂

Hi Matej.
I double checked it. The ssh_config file controls the Raspberry PI ssh connection when it is used as client. The sshd_config, on the other side, controls the ssh connection when it is used as server. So, the right place should be sshd_config and I’ve updated my tutorial accordingly.
Many thanks for your feedback, Giuseppe

Only one question:
the command useDNS no is in ssh_config or in sshd_config file?

Thank you. I was having intermittent hangs using my Pi Zero 2, using the latest 64bit OS. I have been using Pis for several years now and have never had this problem before.
I disabled pam_systemd.so and pam_chksshpwd.so as you describe and the problem seems cured. So far so good.
