It happens every 5-10 minutes now, especially during peak hours. ]]> http://www.dslreports.com/forum/remark,20797012 Tue, 15 Jul 2008 20:49:04 EDT http://www.dslreports.com/forum/remark,20772652 koheisho : I just recently (maybe a week or so) started experiencing the same problems you describe in the 60005 zip code in Arlington Heights. Specifically while playing CoD4 and Crysis on-line, before that my connection had been rock-solid. One thing that I noticed specifically was that the modem has been losing synch, i.e. all the lights except the DS light and power light go out.
I had a technician out today who stated the the upstream signal strength was to high, (in the 50's) and he added a 6 db filter to the line. That did not resolve the problem. He then replaced the splitter on the outside of the house and replaced the Arris modem as well. A half-hour after he left the problem re-occurred several times. I have noticed that the synch seems to fail mostly under heavy load, such as the initial server poll in Cod or in Crysis. I'll update you if I get any more data.

WOW customer in 60005]]> http://www.dslreports.com/forum/remark,20772652 Thu, 10 Jul 2008 22:04:22 EDT http://www.dslreports.com/forum/remark,20756500 Inflex : You're not showing any packet loss.

The "loss" at the first hop is just a CMTS that's has ICMP reply set on a low priority.

A 5 - 10 second hang every 30 minutes isn't bad, I would suspect a server sync issue instead of packet loss on your side.]]> http://www.dslreports.com/forum/remark,20756500 Mon, 07 Jul 2008 23:34:58 EDT http://www.dslreports.com/forum/remark,20755280 Sypher133 : Here's a trace when my router is plugged in. Results are much worse.

My game would just hang for about 5-10 seconds, then everything would be back to normal. It happens about every 30 minutes or so.

Trace complete.

It looks like the problem is occurring from sprintlink.net network. Averaging 10%-50% packet loss.

Anyone know how to fix it? Anyone else having similar packet loss?

Your comments are appreciated. Thank you ]]> http://www.dslreports.com/forum/remark,20755164 Mon, 07 Jul 2008 18:48:07 EDT
