Are you sure it is not a problem with the router?
Maybe dropping the connection due to no traffic.
Try pinging your router every 5 minutes.
crontab -e
00,05,10,15,20,25,30,45,50,55 * * * * /bin/ping -c 1 1.2.3.4 > /dev/null

Where 1.2.3.4 is the address of the router
This will send one ICMP ECHO_REQUEST every 5 minutes.

If this works, talk to whoever is managing the router!
