Constant disconnects

I'm been noticing my Internet drop often on my Sophos UTM Home. It seems to do better after a reboot but only for a day or so. I thought it was my old Atom-based build with 2 GB of RAM (hardware about 10 years old). But I moved it to a Core 2 Duo E7500 with 6 GB of RAM (along with the dual port Intel NIC) and have the same issues. I noticed this in the log:
