CM1200 intermittent connection issues.
I have had my ISP send out technicians multiple times now and they have checked signals on the coaxial cables and replaced fittings outside the house and within. They also checked my ethernet cable ru...
Your power levels are low. They should be between +7 dBmV and -7 dBmV. For reference, see the first three sentences at the top of this article: https://kb.netgear.com/24311/Power-level-guidelines-for-a-NETGEAR-cable-modem-router.
It would be very helpful if you would flesh out your term "intermittent connection issues" with some details. Such as connection via Wi-Fi or connection via Ethernet? Connections to what specifically? Is there some action you take to remedy the situation or just wait it out?
If the connection is via Wi-Fi, do you have lots of close by neighbors with Wi-Fi devices or are you out in the county by yourself?
the power levels are low and you have a ton of errors.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.- Thanks Plemans,
The technicians checked the coax for everything you're mentioning here and replaced all the connectors just in case.
- That's interesting about the power level because when the technician checked coaxial right at the modem he said everything looked fine. But yeah that's obvious it's a weak signal.
More detail:
For both wifi (like our phones) and ethernet connections (like our "cable" boxes) there will be 30sec to several-minute connection drops that happen maybe 10 or so times an hour. If we wait the connection comes back automagically.
We do have a lot of close neighbors nearby, but as I mentioned we experience this with devices that are wired in as well like our living room cable box.
