If your ADSL modem is also your router, and you are using NAT, then it
is not killing your connection. It is merely removing it from active
connection queue after 3 min or so of no activity.

If your ADSL modem is not a router, and "disconnects" your connection,
then the ADSL modem is broken. If you have a NAT outside the modem,
then it is the NAT that is timing out, not the modem.

TCP_KEEPALIVE messages are only useful when you have a non-public IP
and/or using NAT and/or want PostgreSQL to close connections where the
client has disappeared.
