Pepwave Surf SOHO LAN connections dropping?

I have been having issues with my ethernet connected devices disconnecting from the Surf SOHO router at least once a day. My wifi connections are unaffected. The router was working fine up until a month ago when I relocated it to a more central location. My cable modem is an ARRIS SURFboard and appears to be working properly. The only thing that works is a reboot of my router which I can only perform on my MacBook Pro laptop. My security system is connected via ethernet and goes offline at least once a day necessitating the reboot of the router.

I suspect that I have something configured improperly but after going through the manual I have no idea what it could be. Anyone have any suggestions. Thanks in advance!
