      My ISP drops out once or twice a week. Much of it due to local construction, I believe.

      Anyhow, after the modem comes back online, some clients recover immediately but others seem to take forever or never recover.

      I've found that if I restart my SG-1100 everything comes back up rapidly. But that's inconvenient and impossible if I'm not home.

      I did implement the setting to block attempts by the cable modem to assign addresses to clients if the pfSense router loses internet.

      Is there a way to force the SG-1100 to immediately cancel and reissue DHCP licenses upon regaining WAN connectivity? Or am I barking up the wrong tree with that idea?

      The SG-1100 is on the latest firmware revision and works flawlessly, until these internet disruptions occur.

      Thanks all.

        @NGUSER6947 Can you give more details on what doesn’t work? Is this an IPv6 problem? IPv4 with NAT shouldn’t be an issue because that’s all internal to the LAN.

        Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
        When upgrading, allow 10-15 minutes to reboot, or more depending on packages, and device or disk speed.

          @SteveITS Well, some clients seem to come back up very quickly and others don't connect.

          Which does what seems to be arbitrary. Otherwise, if I restart the SG-1100 everything comes back fine. If I just leave it alone, sometimes one laptop will get online immediately, other times it may not but a different one will recover.

          I think IPV6 is a non-issue. I don't think any of my clients are using it

            come back up

            What does "come back up" mean, though? Not getting an IP address via DHCP? DNS failing to resolve? Can ping pfSense but not the Internet?

            In a normal situation I'd expect everything to immediately start working when the pfSense WAN comes back online. DHCP on LAN should work regardless of the pfSense WAN status.

              Have you tried to set the latency to a different mode?
