I just happened to have a network loss. 'mtr www.freebsd.org' comes up with an empty window (unlike previously when the mtr window listed many hosts on the route)

Running 'netstat -i' twice at an interval of about 1 minute produced the following :

Then I ran (as root):
service netif restart
service routing restart

At this point, I get my network back  : - )

I was a bit hasty in sending the previous update. There was another outage a few moments back, and restarting netif/routing did not help. Rebooting the system did.

'service routing restart' produces the following output :

/root <<: service routing restart
route: writing to routing socket: No such process
delete net default: gateway 192.168.1.1 fib 0: not in table
delete net fe80::: gateway ::1
delete net ff02::: gateway ::1
delete net ::ffff:0.0.0.0: gateway ::1
delete net ::0.0.0.0: gateway ::1
add net default: gateway 192.168.1.1
add net fe80::: gateway ::1
add net ff02::: gateway ::1
add net ::ffff:0.0.0.0: gateway ::1
add net ::0.0.0.0: gateway ::1

Is this okay, or is there some problem you can spot ?

Thanks for any further help
