[Connectivity] [Pickerington, OH] packetloss

My friend in Ohio is noticing a good amount of packet loss with his ISP, which is through Insight. I had him run pingplotter and so far it appears to be 20 - 40% packetloss.

Anyone else experiencing this issue?

So is Insight his ISP, or is he using an ISP that is reselling Insight bandwidth?

If he has Insight in the Columbus,OH area, the internet is a partnership with Road Runner, so while he pays Insight for the Internet, RR is providing the actualy bandwith, but all support is done by Insight.

The ISP is Insight, which appears to be reselling from Road Runner. I did notice the RR in the ping results, so perhaps Road Runner is having an issue?

Actually I forgot to post the plotter info last time, it's now uploaded as an attachment.

That is RR's network no doubt. Looks like the routing issues are in the backbone of their network too.

that is an absolutely normal trace route.

Zero packet loss at the destination, god ping times.

The packets in the middle that generated no response reflect the intentional configuration of the routers whose CPU have things other than ICMP packets to deal with at higher priority.

So your saying that the routers are configured to drop ICMP packets if they have "better" things to do? In that case why not just stop responding to ICMP echos altogether? Also the customer was complaining that it was effecting service, his original conversation was about that, rather then the ping-plotter results.

Many routers are configured to not respond to any ICMP packets.

I don't see in his post any remarks about anything other than "packet loss".

By the way Insight does not resell RR, they are a licensee as is TWC.

EDIT: The OP may wish to review this page:

»Road Runner HSI Forum FAQ »Connection troubleshooting; Please Read Here first!

and post some more information so that folks can help.

Well what I was saying was is I read into the post, people don't generally post with issues unless it is effecting their service. Also I understand that some routers are configured not to respond to ICMP requests, but these responded with packet loss. If it was a total 100% loss that would make since, but they are core routers and most are setup to respond to pings. Either way, I still think there is some packet loss somewhere on the line, maybe not at that router, but somewhere.

TO OP:

Read that link that Kip posted and reply to us with that information so that we can get a better picture of what is going on.

Thank you for responding. The problem was noticed while multiple people were using the router, Linksys WRT54G, to access the internet. 3 computers and a PS3.

Slow webpage loading or timeouts and disconnects from online games were observed. No torrents or mass downloading of any sort were occuring at the time. After investigating the router and the cable modem, powercycling both, the problems reoccured. At this point I ran the Pingplotter program to see if the problem was further upstream and noticed the packet loss.

I didn't want to get too far into troubleshooting at BBReports, just wanted to see if anyone else might be experiencing similar connectivity issues around the area.

I appreciate the eagerness of wanting to troubleshoot this, that's what I love about this website. I'll keep the ICMP priority response in mind. The problem seems to have died down for the moment, so nothing further to add. If it does rear its head again, I will provide a more detailed entry. Thanks again.
