Adding to my original post

1. Firmware on the CM1150V is 4.02.02

2. There is one splitter before the modem:  Extreme Broadband Engineering BDS102H

Thank you

Is this with a WiFi connection ? If so, for a test, does a computer / device that is hardwired directly to the router / gateway device with an ethernet cable have the same problem ?


With this test, we are trying to isolate this from being either a WiFi-only problem or a problem with the general connection to the Comcast system which would of course affect both. It's a good first step of troubleshooting before proceeding any further.

Thank you for replying. 

Yes, the problem exists for the devices hard wired & connected via Wifi.  The problem is intermittent.  As of right now, everything is working fine.  When they occur, my network still shows up as connected, however, I get an error message saying the internet is not available.  

This is my setup:  CM1150V is connected to a MikroTik RB4011 router.  The router then distributes to two desktops (via ethernet) & to two wireless access points for 2 separate networks, both connected via ethernet.  One is an Orbi RBR50, which is configured as an access point and the other is a Netgear AX1800 access point.  Also, the Orbi setup has two RBS50 connected to the RBR50 via ethernet.

I have attempted to direct connect to the cable modem, however since the issue has been intermittent, I have yet been able to recreate.

O/k, the upstream power is on the high side and it may be intermittently fluctuating even higher to out of spec levels. 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 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 5-1000 MHz, bi-directional, and no gold colored garbage from Radio Shack, Home Depot, Target, 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, 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 !

Thanks!  The only splitter on the line before this is an Extreme Broadband Engineering BDS102H.  It is rated 5-1000 MHZ, however I have no idea of the age, might be 10+ years old.  It is indoors, but I will disconnect and check for corrosion / oxidation.  Appreciate the input.  thank again!

Quite welcome ! Is it a two-way splitter or a larger one ?

O/k that's fine. So if nothing applies, then you'll need a tech out to investigate as was 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 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 !
