ping sometimes fails on the network
Posted on 2011-05-10
I have a client where everything seems to be working pretty well. Nslookup always returns a value, emails and surfing are responsive. But every once in a while, we get a "stutter" for lack of better description. The router/modem stays online, doesn't seem to go offline, but it wills tall communication to outside world. I did a ping 184.108.40.206 -t and found that every 50-6th ping, it gets a "request timed out", then picks up right where it left off. At the same time I was pinging the gateway and the router, just in case the router was getting flooded or not responding, but internal IPs all reply rock solid, never misses one. The outside address also rarely times out two trys in a row.
The cable company insists their gear is perfect and my side of demarcation is bad, what other tests can I provide to prove otherwise?
