My Omnia router has been running faultlessly for many years. But after it autoupdated to 7.2.0 I was not able to connect to the network at all (‘Network is unreachable’), so had to rollback to 7.1.4 which works fine. (My Omnia router is from March 2017 if that may explain why I’m having this problem).
I have tried updating 3-4 times more via re-Foris, and also ssh-ing into the router and running pkgupdate, but with the same result each time (losing network connection).
So for the time being I have had to disable autoupdating, and stick with 7.1.4.
