[Cable] Anyone else getting packet loss?

For the past 2 days i have been loosing about 1% of my packets and getting occasionaly ping spikes. Im on the Greensboro POI (im in north york). Anyone else getting the same issue?

I lost 1 packet out of 250 in this test, same server.

PS: first post, don't bite please x_x

I wouldn't worry much about 1% packet loss, especially since your ping is still low. The problem could be happening anywhere between you and the test server, and might only impact that one test server.

Indeed, 1% packet loss could be lots of things...If it was only temporary, don't worry about it.

I wouldn't write it off quite so quickly.

I'm seeing persistent 1%-10% packet loss. Not 24x7 but certainly some loss every day. TSI so far seems to be unable to locate the issue. I'm on DSL but it looks like the issue is not line related so it may be something in TSI's core network in which case it would impact both DSL and cable customers. It typically starts around noon and gets worse until about midnight at which point it improves again.

So while it may something random if it keeps cropping up I'd hazard a guess that it is the same issue.

Forgot to mention, i tested quite a few servers...

still getting packet loss today:

Only posting one test, but i tested several servers across north america with similar results.

day 3 of packet loss issue, although i do notice, when i get very little to no packet loss, my ping spikes. Probably software related.

I'm not too worried, was just wondering how many more people are getting this issue. Not too worried since i don't play games much these days although it affects browsing experience too, albeit not by much.

EDIT: i was getting 1-10% packet loss 2 days ago. now its 1-5%

EDIT 2: my backup DSL internet (not teksavvy) isn't getting this issue

Cable modem and router? If you got 1-2 days of 1% packet loss I wouldn't be worried about 3 days? Hmmmm.

it could be the modem, but it's not the router. I get the same results on a direct connection to the modem, on all my computers. If its the modem...that would be unfortunate. I did get the modem from teksavvy over a year ago. Its a Thomson DCM475. Both DSL and cable modem's are from Thomson >_>

What the modem is telling me right now:

I appear to be on the correct software version, and power levels are stable.

Those downstream power levels, while within tolerances, are definitely not optimal. I'm not enough of an expert to say for sure if that could be causing the packet loss though...it seems more likely that you'd simply lose your connection entirely if the modem couldn't hear the CMTS.

power levels are determined automatically by the "box" (as i call it) or CMTS and the modem (from my understanding). I'm less than a kilometer from the box, and when the Link On communications guy came to "install" my internet, he replaced the coax cable connecting my home to the electric post outside. Then he showed me a 10dB+ decrease in power levels saying how the old line was really bad. I don't even know how old that line was

According to the message Cogeco left Teksavvy, I am.

My loss must be very high as I'm not getting channel bonding and my speed is cut in half.

There was a time when those levels would have been within spec as Mongoose stated. However, these limits have been modified on the Rogers network. While they are not drastically out of range, the forward path power should not be above 11.

For starters, I would recommend posting in the direct forum here: »TekSavvy Direct with your account information so we can look into getting a ticket going for you to have Rogers look into the line.
