packet latency and loss

for the last 3 days I cannot work, as Im having packet latency issues, what causes this?

What data do you have that shows the latency? Are you going by the Ping number in a game? Pingtest.net? A tracert? Could you post it?

Also, how are you connecting to the internet? Wired or wireless? What modem and router do you have?

I had to ping my work system,  I have a wired connection,  I have a box that says Arris, and one that says Ubee,  i dont know which one does what  here's the avg on the ping test  http://gyazo.com/c6a1200552456fe34c3de03cf7591df2

I think I might step this one out. Good luck!

ozarkbees,

Have you run any other speed tests?  To determine where the latency is happening we'll need to have you run some trace routes.  Can you run 2 speed tests and 2 trace routes to 2 different websites?  You should be able to copy and paste the results into the forum post.

I'm seeing this too, on the RI system (Connecticut). 

Here's the standard deviation for ping times for a few sites:

Hosting provider 389 ms
Google 378 ms
cnn.com 293 ms
wfsb.com (Akamai) 98 ms

That's not the ping time—it's the standard deviation across ten pings, the variability in ping times. 90 ms is getting a bit high. 300 ms is absurd, and a sign of equipment failure somewhere. Pinging Google should not result in ten results ranging from 44 ms (normal) to 1039 ms (extremely abnormal). 1,000 ms is the ping time you'd expect from a spacecraft that's one third of the way to the moon, not a Google server someplace on the same continent as you...

Also seeing substantial uncorrectables on the modem, less than two hours after reboot:

I took a look at the modem from here however nothing appears out of the ordinary at this time.  Are you still experiencing any problems?

@ChrisL: Yes, I'm still seeing massive latency spikes. As best I can tell from traceroutes, they're occurring close to me network-wise. If I ping the first hop in my traceroute (local node? hubsite?) I'm seeing the issue:

Same story with almost any destination IP. Ping times spiking up over one second. NTP can't get a solid lock, there's too much jitter in the latency to keep good time. Online games like Diablo III are unplayable. VoIP is unusable.

By the way: I've noticed my modem occasionally spiking its upstream power over 50 dBmV; I understand that's out-of-spec for DOCSIS 3.0. My drop is underground RG-11 installed less than two years ago. It runs to one Cox-installed amplifier; one leg of the amp output goes to the modem (via the power inserter). The other leg goes to the TVs.

We've had a lot of outages lately. Does Cox need to replace some equipment in this area or something?

Outage: Feb 24 2015 00:40:22 EST

Outage: Mar  9 2015 00:37:12 EDT

Outage: Mar 13 2015 01:00:12 EDT

Outage: Mar 15 2015 22:37:12 EDT

Outage: Mar 16 2015 01:35:12 EDT

The fact that this issue started after the most recent Sunday/Monday outages seems suspicious.

I checked again and I'm still not seeing any loss or abnormal latency between us and the modem.  Can you try connecting a different device directly to the modem and testing again? -Chris
