Internet connection dropping

I have premier service and the internet connection is dropped every day consistently.  I have a netgear CG4500BD cable modem/router supplied by cox.  I connect computers/smartphones to the router wireless.  No ethernet connections.  Here are some connection signal pastes and event logs. It appears that SNR is not optimal, but not extreme. MAC addresses are edited.

Modem is connected directly to an outlet with no splits and no other electrical connections.
