Hello, and thanks in advance for any help. I know very little about router/modems. I believe my C7000 100-NAS is the cause for often times slow internet to no internet. The 3rd light down from the top is orange. We have Xfinity. We have anywhere from 10 to 13 devises logged in at any one time even though only a few are being used at this time. I believe I have an upstream issue. Seems like everywhere I read, most have 4 bonded upstream channels locked. I only have one locked. I have 24 Downstream locked. Please see attached screenshot and thanks. I tried to paste it here but can't seem to do so. I'm on a chromebook if that matters.

do you have a screen snip of the reset of the downstream as well as your event logs? that helps check the line. If you have any splitters, amplifiers, or signal attenuators in your line, remove them. check your coax for kinks, damage, old/bad/cheap/loose/corroded connections and replace them if you do.

We have at least two splitters. Also, our ethernet cable is a bit ragged. So, what I thought I'd do is run new cable and an ethernet and see if things change before I do anything else. It was working fine and slowly got worse then bad. We did have our internet speed upgraded to 400 gps. I was thinking of getting a new router & modem but I don't have $400 to spend on that. I assume Xfinity would charge for running new wire. I'm not quite sure how to get "the reset of the downstream as well as your event logs?" Thanks.

See how well it works and how the signal/speeds do at that point. If they work well, then you can run the wire. Xfinity does charge for running wires interior to the home. Everything exterior to the home is on them but inside, they charge for issues. Meant "the rest" not reset. The rest of the downstream info and logs help with the full line check. sometimes its just a few channels with issues.

Thanks again. I attached the rest of the downstream data....at least I hope I did. I'll try to move the modem/router to where cable comes into our house. There's certainly alot of info about our router/modem when I sign into it. I just wish I understood everything. Despite the regular channel and the 5G showing "strong" signal, our computers sometimes just spin until we get "this site can't be reached."I selccted to run diagnostics on my computer and I attached that as well.

see attached part 1 of downstream
