About 10 feet. The splitter was changed twice. The 10 foot cable was changed once. Both Cox and I have looked at the signal levels in the modem and they have * never * been bad. Cox has also but their Barney Box (JDSU tester) at the modem end of the cable and checked levels a few times.


Also, we tried moving the modem physically and using a 1 foot cable to the splitter. No help.


The TV has no problem while the packet loss is taking place, by the way.

How long is the run from the tap to your cable modem? I think the normal coax loss is 1 dB per 10 ft.

How do you track this? Manually, or with some program that reports ping attempts?

Hello Jerry.


I have a Cisco DPC3010, straight from Cox (twice). It allows access to the status page ( which includes the signal level info. My signals are always good, even when the packet loss is taking place. Others in my area have the problem also. So it’s not a problem on just my feed.


Sometimes problem seems to correlate with high-usage times (late afternoon, evening), but not well enough to say there is a casual link. For example, I saw loss of over 1% yesterday during these periods:


    00:50 to 01:00

    03:00 to 05:00 (up to 10%)

    15:40 to 17:00 (up to 12%)

    19:52 to 19:59 (up to 25%)
