Thanks for the reboot tips. A full power cycle often drops my WAN for several minutes and the fiber ONT doesn't seem to like it so it would be nice to reboot and not have to wait for WAN.After having uninstalled and reinstalled Diversion from amtm the problem did not occur anymore.
It's about 10 days. I also reconfigured the DHCP to start IP allocation from 192.168.1.2 (before it was assigned to Diversion but now no more needed from 5.0).
Instead of powercycle you can reboot from amtm or run "service reboot" (simple reboot does not solve the issue).
It seems the packet loss is not the issue here even if I am still monitoring if the problem occurs.
Please advise if the Diversion uninstall/install solve the problem (in the Diversion page it is stated that the upgrade should be done from amtm and not from WebGUI); this might be the reason why I had problems; I see you did the same
I did the Diversion upgrade from AMTM, not the WebGUI. What I meant by "inline" is that I didn't do an uninstall first and then install.
Will post an update after several days of testing, and fingers crossed it's sorted.
