random loss of internet connectivity after latest patch

Gary21
I updated my utm to 9.113-1 about a week ago.  Ever since the update, I have been losing internet connectivity 1-2 times a day.  After I do a reboot of the FW everything works fine until it happens again.

Any ideas of how to address? 

Thanks

    Apparent RealTek NICs (and not Intel) should rule out e1000 driver related problems.

    "No route to host" for cffs ping checks.  Is that common and consistent for the times the system is without connectivity?
      
    Any establishable pattern:  Every n hours, every n hours after reboot?

    Check for link, accessibility of upstream device(s), routing table entries: disabling/enabling the WAN interface when "down" and physically cycling the link (cable pull and plug), upstream device verification/access mechanisms vary, WebAdmin->Support->Advanced (or CLI).
