Netgear CM1200 Modem Drop outs
We have our own Netgear CM1200 Nighthawk modem. The internet has been randomly dropping out for over 3 or so years. I had several techs stop out and replace the cable to try and help and it doesn't correct the problem permanently. I started having this problem when I had a Netgear CM500 modem and then I switched it to the Netgear Nighthawk CM1200 thinking this would correct it and it hasn't. The firmware is up to date on the modem, but I am still receiving several errors a day from my modem when you log into it. I need advanced tech support to help me figure this out. I keep reading online and other people have had the same problem and it always seems to go back to the ISP wiring has an issue.

The upstream power is too high / out of spec and it may be intermittently fluctuating even farther 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 more that can be done to improve the connection quality, then you'll need to get the techs involved again until it gets fixed properly.
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 !
