MB8600 - High packet loss occurring
Hello,
over the recent days I've noticed a high amount of packet loss occurring during normal use of my home internet. This led me to check my MB8600 status page and I see so many uncorrected errors on my OFDM channel 29. Running various traceroute and ping tests are leading to slow traceroutes and ping tests where I loose anywhere from 6-12% loss or even no connection on back to back tests. This started a few days ago and the reconnects just trying to do something on my home internet are driving me insane.
--- google.com ping statistics ---
213 packets transmitted, 200 received, 6.10329% packet loss, time 212594ms
rtt min/avg/max/mdev = 10.986/18.572/31.768/3.035 ms
user@host:~# ping google.com
ping: google.com: Temporary failure in name resolution

The upstream power is too high / out of spec. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.
In an effort to try to obtain better connectivity / more wiggle room, check to see if there are any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage from Home Depot, Target, Wal-Mart, etc. Splitters should be swapped with known to be good / new ones to test.
Also check the coax cable for any damage such as cuts, nicks, abrasions, kinks, sharp bends, etc.
If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two-way splitter connected directly off of the drop from the street / pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
Good luck with it !

If there is nothing that can be done to improve the connection quality, then you'll need a tech visit as stated.
Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it up to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home. And if the problem is found to be on their side of the demarcation point, there will not be any charge.
Good luck !
