Hey,
For years I have had isp issues with my cable internet. New modems, routers, and lines inside and outside house haven't helped. Recent months it has been especially bad.
In the evening, speeds go down to around 5 Mbps or below but are supposed to be 75 mbps. Dozens of tech visits haven't helped until last week. A bucket truck showed up and fixed an issue where my modem was only showing 9 of the usual 16 downstream channels. It stayed showing 16 channels for a few days after the tech left, but tonight it is back down to only 9 channels again and also the really slow speeds. Downstream channel power levels are around 10-11 dbmv. Upstream is around 40-43 on both channels. SNR stays around 40.
Last winter I always lost internet and channels when it got cold out and the power levels would go way out of range, but like I said, the power levels stay pretty steady now whenever I look, so they must have fixed a little of the issue at some point. Weird thing is, my upload usually stays around 7 mbps which I think is around what it should be.
Also, my modem only started losing these 7 channels for about the last month or so. It does not seem to be happening only when it is really cold now though as compared to last winter because right now it is in the upper 60's Fahrenheit, so the temperature doesn't seem to be the problem to me but I could definitely be wrong.
As far as I know, my section of the tap only has me and one other property where the house burned down years ago, so no one is on that property anymore.
The last tech that finally solved my lost channel issue for a few days said he had to balance a couple of amps I believe. He has been here several times over the last couple of weeks. One important point he did make was, he said his previous visit a few days before the last one, he said he adjusted the amps, but after he came back a few days later, he noticed they were off by around 5 db from what he had them set at previously. So I guess the amps apparently came out of adjustment on their own for some reason.
ANY help at all is definitely appreciated. Thanks
