Reply packets received = good
Reply packets not received = bad
Response time in the 10s of ms is fine.
I never get a response from pprune.org. Not all sites respond to ping, so you may get no replies even though the connection is OK.
Question is, did you see the address resolved to an IP address?
You need to do this in order:
Ping loopback address 127.0.0.1
Ping local IP address (self)
Ping other local IP address (if possible)
Ping gateway / router IP address
Ping external IP address e.g. 212.58.244.67
Ping external host name e.g. www.bbc.co.uk
See where it fails.
