I am using the ping utility to troubleshoot what seems to be a slow Internet connection on my home network, but I'm finding the results unusual and difficult to interpret.
I have a Linksys wireless router, and have tried the following simultaneous tests: pinging the the router from my computer, pinging google.com from the router, and pinging google.com from my computer, via the router. Pinging the router from the computer, and pinging Google from the router both work as expected, with minimal packet loss, and low round-trip time ( min/avg/max = 1.601/3.465/9.926, and 20/20/70 respectively).
However, pinging Google from my computer, via the router, reports something that seems very strange to me. It reports a low RTT, and minimal packet loss, but the interval of each ping request, which should be the default 1s, is more like 10s. What this looks like is about a 10s delay between each time ping prints some output. But the resulting RTT is low, e.g.:
64 bytes from 74.125.226.115: icmp_seq=31 ttl=52 time=29.2 ms
When I run this side-by-side with the other tests, the other tests will have sent about 100 requests at the time that this test will have sent 10. This seems to contradict the low RTT reported, so I'm not sure how to make sense of this.
I'd appreciate any insight anyone can offer.
