UMC system diagnostic module hangs for a long time

If the gateway doesn't answer on ping request, the UMC system diagnostic module hangs for a long time, several minutes. See attached screenshot. It is not really clear if the module is still doing something.
You can simply reproduce it by dropping all outgoing ping requests:
iptables -A OUTPUT -p icmp --icmp-type echo-request -j DROP
I think it is a common situation that a gateway doesn't answer ping requests. At least we got this feedback.
The command is currently:
/bin/ping -c1 -w500 gateway
I hope this command will fix it:
/bin/ping -c1 -w500 -W500 gateway

Omg. -w takes seconds not milliseconds.
Changing it to /bin/ping -c3 -w4 -W4 gateway
OK - debian changelog
OK - yaml
OK - gateway ping does not block diagnostic-module anymore
