Re: Best way to test latency?
An exit command in crosh literally closes it The browser window disappears, haha. I found guidance on the net that a shell command in crosh will take you to the root linux shell, so I tried that, but it returned 'unknown command.' I dunno,I give up for now. I will eventualy have a chance to bring a windows laptop to this location. I will have the chromebook at a place with cable internet service later next week, and I'll try pinging and tracepathing there, just to see what happens.

I tired typed 'su' and it returned as 'unkown command."

Re: Best way to test latency?
MarkjFine, you said, "If you can ping to any of those hop locations manually," don't know for sure if this is what you mean, but I tried this: My second hop washost977219357.direpc.com. I tried a ping command to that, then I tried 977219357direpc.com, and finally I tried just direpc.com. All three returned with 'name or service not known.' I also tried a tracepath command with all three of those, same result. I guess my first problem is nobody in the conversation knows for certain how to do a traceroute with a chromebook. What I found via googling is that tracepath is how you do a traceroute on a chromebook, but I have no expertise to know if that's right, and applies to what we are using it for.

Re: Best way to test latency?
MarkjFine, So one doesn't add up the ms values on each hop to determine one's total round-trip latency? But rather, the ms value at far right on each of those lines (i.e.1471.185ms on the third hop 3 line) reperesents a total round trip latency? When I do a ping command, I get ms numbers on the right of each line in the 600-900 range, which seems more expected. Does that indicate that those 1-1.5 sec. values on each line after a tracepath command are probably not accurate? Or is the ping command not accurate? When you talk of the possibility of a network compatibility problem, what networks are you talking about? I'm a guy in central florida using my Hughes service to ping amazon.com, why would any of the networks used to execute that very common route for me have incompatibility issues?

Re: Best way to test latency?
and I get it, 600-700 is normal latency for sat and there's no way around that. I'm just looking to diagnose or understand why I sometimes experience slow or erratic performance, and yet my mbps download speeds are the same as when the performance is normal. So I wanted to figure out how to check latency the next time it happens, to see if that explains it.

Re: Best way to test latency?
Sounds like you're saying that if my latency is high, the odds of it being a problem with Hughes is very tiny? Are there any other variables? I know there are variables on my end, I mean otherwise. I know that periods of high traffic can affect performance, but I assume that's reflected in the mbps number when I do a download test.

Re: Best way to test latency?
My initial tracepath attempts were for netflix and google, which didn't work. I decided to try again with amazon.com, and it seemed to work -- screenshot is below. I have no idea how to read the information. How do I read the latency in Hughes's piece of the chain, and what's a normal value for the their piece? What would be an unacceptably high value for their piece?There are times (not right now) when even simple browsing for me on Hughes seems very slow. Or maybe more accurately, it seems erratic. One minute it's doing well, a minute later it's crawling, then suddenly it's better again -- but when I check mbps, it's reasonable. The other variable besides mbps that I'm aware of is latency, so I just want to be able to diagnose when I'm getting slow performance by also checking latency. Or more specifically Hughes's latency, since that's the piece of the chain I'm paying for.

Re: Best way to test latency?
Is there any relationship between speed and latency? I ask because I'm wondering if checking latency is a shortcut way to check if you are having bandwidth/speed problems. Doing this test is so much quicker and easier than running a speed test on testmy.net, for instance.

Re: Best way to test latency?
Thanks! I just ran it comparing wifi to ethernet cord.Virtually no pings above 700 with ethernet cord. Cutting out the wifi seems to shorten the delay by somewhere around 30-70 ms.

Re: Best way to test latency?
Found a video that said to use 'ping' as the command on a chromebook. It just keeps pinging until you stop it, here's the results. Looks like I'm getting mostly in the 650-700 ms range with sometimes wider variation. Is that normal?
