Internet disconnecting this whole week

Tech came out and said "everything looks good outside" but that also happen to be when the internet was working. I have to reset the modem each time and hope that it works again. He said I need a new modem. I have tightened all the connections I know of inside and this house is a new build.

Not sure where my other 3 upstreams went.

Re: Internet disconnecting this whole week

The upstream power is way 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 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 book a tech visit to investigate and correct.

Re: Internet disconnecting this whole week

I only have one splitter that Comcast installed. It has one in and 4 outs. One goes to the living room with the modem and the other 3 go to each bedroom but have not been connected to anything. I will check each connection for corrosion. I can't post the picture of the street connection to the main outside the house but there are wires exposed in that connection. (EDIT: those seem to just be the cable support strands)

 

I tightened everything. No corrosion. Let see if everything stays connected.

Re: Internet disconnecting this whole week

Wow ! The upstream power is way down now. It should not be making such wide swings like that. There is something intermittent going on with the line / connection.
