Tech came out a few weeks ago & replaced loose external connectors. We had service to was up to spec for a few days, but is getting more erratic. DSLReports gives good DL speeds, but UL speeds have been spotty. Uplink light also keeps blinking
After spending the morning trying to work from home, I chk'ed the signal etc, rebooted & chk'ed again (ouch)
the top one is after the modem reboot.
Time for new hardware here or does Comcast need another visit?
The upstream power is too high / out of spec. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, and latency problems.
In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there 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 types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test
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 get the techs re-involved until it is fixed properly. Good luck !

The upstream power is still too high. The numbers don't lie. Something intermittent is going on. Their is an impairment of some sort. And only 2 channels are locked in. Should be 3 to 5. Have you done any of the tips ?

You are going to need to get the techs involved. 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 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. Good luck with it !
