I am fresh owner of a Revolution Pi 4 and started my experiments.

On May 17 I made all the updates, and suddenly the ssh connection became absolutely unreliable.

If I only login and do nothing, connection stays stable, and if I execute commands with only expected little output,
connection stays stable to (e.g. dmesg | tail)

But as soon as I want to have some more, connection freezes and
after a while connection quits with

Code: Select all

Timeout, server servername not responding.

I found out, that it was due to MTU, after changing the MTU value for the interface, connection is now stable.
