You might want to enable TCPKeepAlive. It could, at a very least,
prevent disconnections without explicit user interaction.=20

$ grep -i keepalive /etc/ssh*config
/etc/ssh_config:TCPKeepAlive yes
/etc/sshd_config:TCPKeepAlive yes

Despite the man pages for ssh_config and sshd_config stating that it
is enabled by default, I had to explicity declare it to prevent ssh=20
connections _from_ a cygwin box to the outside from dying.
This was a while back, though.

Regards.
