Last week I had a different problem (see below for that problem.)
Current problem:
On Friday, a tech switched out my Comcast leased modem-router for a TG1682G. I forgot what model I had that was replaced.
My connect, after the new modem, worked fine until Monday.
Starting Monday, I noticed a little lag, was dropped from a game I frequently play. Rare that I experience either but it happens from time to time.
Then Monday night it progressively got worse. It got more laggy and I started getting "no internet" warnings in Chrome and in Edge. This would happen for a minute or so, then it would be good again for about 5 to 10 minutes, then more lag and errors. Also, in the game, I would get cut after just a few minutes over and over. None of that stuff has every happened since I have had Comcast service which goes back to early 2012.
After an hour or so of the lag and errors, my PC network indicator would go red (no connection) and I would have no connection. Trying 10.0.0.1, I would get no response. All that was on a PC via an ethernet connection. My wifi devices could also not connect, nor could other ethernet connected devices (all would give no network connection when queried about network status.) The modem would appear fine. All its light would be on indicating it was working fine.
I would turn off the modem, let it reboot, and everything would work fine but only for a short time. The above described bad to worse progression would repeat after just 5 to 10 minutes. I went through that scenario of reboot, to normal to worse to no connection a few times last night.
Today it has been a little better. The lag periods have not been as bad and not as severe and they do not last as long but they are noticeable and a night and day difference in how my internet normally is. There has been only one actual lost connection today as of this writing.
On the new problem, I called Comcast yesterday. A tech said my modem numbers, when she checked remotely, did not look very good. She arrange for a tech to come out.
I went into the portal of 10.0.0.1 to check on it myself after that call. SNR was around 40dB on all channels, which as I recall is where it normally is for my connection. The CM Error Codewords seemed high. On every channel, there were about 21 thousand to over 40 thousand Uncorrectable Codewords. Unerrorered Codewords were 8 million to 11 million on each channel.
Based on the above described problem, does it sound like a faulty modem-router? Is there something I should request a tech do when one comes to look at this problem?
In case it is relevant, the original problem last week:
That problem was different. No connection for about 20 hours (tried many reboots of modem and none worked.) In those cases, only the power light would come-on on the modem, with US/DS light flashing very fast and all the other lights off. A tech came and replaced that unit, but I am not sure the old unit was to blame.
At the same time that tech came, a field crew was in front of my house. They were working on the drop box that feeds the cable that connects to my house. (similar crews had been near my house all week - they are expanding the node.) They finished their work before the tech and I went into my house to check on my modem. When we got to the modem, all its light were on, appearing to be working. I did not test it in its new state because the tech immediately turned it off to disconnect it. That work-crew project might have been why it was out for 20 hours and it did not need to be replaced.
Another issue: when the tech was at my house, a field supervisor came to my door. He wanted to talk to the other tech. I got her and I also joined the conversation. He came looking for her because he was puzzled why she was at my house, since the markings on her Comcast vehicle indicated she was in an area far away.
After the two talked, he determined that I was clearly on the node his crew was expanding but before that moment he did not know I existed because Comcast had me listed as being in a node 20 miles away (Comcast had my right address etc. but noted that I was on a different node than I really was.) He said he would fix that. I was concerned that changing my account might cause problems since before my service was always good until now. He said nothing physical would change about my service. He said I was physically on his node and that would not change - he would just correct Comcast's records for my correct listed node.
I wanted to add the last part in case it shed any light on my current problem. A Comcast tech, on the phone, told me he had no knowledge of nodes etc. and it was way over his head.
