Hi Andrea,

When the connect drops, is the DSL and internet light on? Do you have WAN IP address on the router's Status page?

Also better to check this: http://www.tp-link.com/en/faq-547.html

Here the modem settings:

http://prntscr.com/hdod74
http://prntscr.com/hdodlj

And the modem status:
http://prntscr.com/hdodxo

After the ADSL mode change from automatic to G.DMT even the log error doesn't expire the connection is a little bit more stable.
