Allen, One thing to do is to determine if you are having issues with the cable signal... you can log into the modem and see what the error rates look like... if they look bad, then there may be issues with the modem, but it could also be outside of the home (ie, problems with the line due to age, moisture, etc... or even problems with the line drivers, etc)... If so, comcast will have to roll a lineman truck to diagnose the line from your home to the head end... getting that lineman out may be a feat in itself as they tend to send out "contractors" to check your house, but they don't have the tools, access, or even the sophistication to do any line diagnostics. So this process could take days, weeks, or even months to resolve... I have gone through this with both my own house, and my parents home - it was a huge pain.
If you are committed to replacing your modem, I would upgrade to a DOCSIS 3.1 model like the SB8200 - while it won't give you any better speeds, the 3.1 spec is significantly better at handling noise and errors on the line... while not 100% certain, its possible that upgrading from DOCSIS 3.0 to 3.1 may solve your problems if the line errors are minor. https://www.incognito.com/blog/a-technical-guide-to-docsis-3-1-and-beyond-part-2-technical-advantages/ thats my 2 cents 😀 good luck, -Richard, N5YOO On Mon, Oct 12, 2020 at 3:14 PM Jonathan Guthrie via BVARC <[email protected]> wrote: > > They won't send a new modem to replace one that you own. > > I have the same cable modem, and I get network glitches sometimes.
