CM1000 losing voice connection?
I have Xfinity cable service, a CM1000 cable modem and Eero Mesh Routers. I work from home, as does my wife. Frequently, during online meetings I lose my voice connection. That is, I can hear othe...
It shouldn't just impact voice/calls if it was the modem.
We can always take a look at your info.
Got a screen snip of the cable connections page and event logs?
that helps us to check the connection.
If that looks good, then I'd be investigating the router setup.
Keep in mind... it's not my normal "voice service". I don't have cable voice service. It's the voice part of a net meeting I'm on. The rest of the meeting continues fine. I can hear them and see the shared screen. They just can't hear me for 15-30 secondfs. Makes me wonder if the mike on my laptop is actually kicking in and out.
You've got errors in the line and in the logs. I don't think its necessarily whats causing it but they are there.
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, bad/old/cheap connectors, or corroded connections. Replace them if you have any issues or suspect cables/ends.
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.Try that. I'd also try a different pc/laptop to see if it is indeed a computer issue
Thanks. I'll check the things you mentioned.
I'll say that Comcast has a GREAT difference in the skills of the people they send out to resolve problems. When I first moved in here I was having all kinds of problems with network and CATV both. Finally, when I got them to send a regional support person out he found all kinds of noise on my lines. Over the years Comcast had put all kinds of crap on my inside lines. They had a signal booster on the line right where it came into the house. Then signal reducers on a couple of the TVs. Everything they put on the line was introducing noise. This tech took everything off all through the house and problems went away. This problem I'm asking about now has only been happening for about a month.
It's interesting I notice from the event logs that the errors seem to come in clusters of a few minutes, 2-3 times during the day.
The modem is connected right where the line comes out of the wall. No splitters. It looks like a good, sealed, store-bought cable, but I might try replacing it. It's as short a cable as I could get, from wall to modem. And, like I mentioned before, the wiring in my building has all the boosters/reducers/whatever taken off.
When I was having those big problems before the SMART tech noticed that the connections where their service came into my building were old and corroded. So he replaced them. It's a condo building so he replaced mine. Said everyone else would have to call in to get theirs replaced!
At that time, when he finished, signal strength was strong coming into my building, strong coming into my condo, and strong at each of the cable outlets in my unit.
I don't really understand everything in that event log but, are you saying it should be close to empty? "Critical"s should be mostly gone, if not completely gone. "Warning"s are not great. And "Information"s aren't a problem?
The modem, and the cable going from the wall to the modem are my responsibility. Everything upstream from there is Comcast's. Is the log indicating a weak signal? Or noise on the upstream line?
Your signal values are pretty spot on. Its just that you do have the errors and log issues.
A few errors aren't a big deal. But you have quite a few on all the channels. Is the signal split at all when it comes into the home?
If so, connect right there without the splitter and see how the signal/errors turn out
