I am using Ubuntu 15.10 using an Ethernet connection to my cable model router. I have not customized the network set up in any way after installing Ubuntu. I've noticed that after about 12 to 24 hours after booting up, Ubuntu starts to drop internet connections. Usually I notice this after webpages fail to load images or CSS files. When this happens I notice that the /var/syslog
is filled with entries like this:

Usually I can recover normal internet use by disconnecting the wired connection using the networking icon in the Ubuntu toolbar and then reconnecting. However, this is troublesome. I would like to keep the avahi-daemon for the purposes of discovery. Does anyone know how to stop this behavior? For the record, here is the output of my ifconfig
