For the past few months I have constantly gone in and out of having any connection at all, massively slow speeds ( 68 mb download on occasion, when I pay for Gigabit). I stream on Twitch and at least once or twice per day, my entire internet going out completely then coming back about 5 minutes later with all kinds of latency issues. I have replaced my Router/Modem combo with the new XB7, have had techs out to the house, reinstalled windows, replaced all my cabling, replaced my network card, replaced just about everything but my ISP and I am just now seeing all the CONSTANT IPv6 input drops, Forward Drops, FW.WANATTACK drops by the THOUSANDS right at the times my inernet becomes shotty. If it isn't the signal, my equipment or the wires, what can this be? How can I stop this? It is driving me absolutely insane and it only seems to affect my Ethernet Hardwired gaming PC on my home network. I can provide whatever you need from me, just really need to get to the bottom of this while I still have my sanity left and before I go out and buy a new PC for no reason whatsoever just to attempt to fix this.
Lots of problems here by the look of it... any help dissecting this would be gravely appreciated, thank you.
Here are my log files:
What do the modem's signal stats look like ?
Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
Sure thing, here are all my downstream power levels, upstream power levels and SNR numbers. ANY help would be great! I am stumped.
I organized all the channels in to one page for the Downstream so you can see them all at a glance, thank you again, hope you are staying safe!
Well the signal stats are fine. And those router component log entries that you posted are unhelpful. Are there any modem component RF error log entries being shown somewhere in the UI pages ? If so, please post them.
I don't have a rental gateway, so I don't know, sorry. I do know that we've seen many posts here recently indicating that they have now blocked the end user from accessing the error logs in the Comcast supplied gateway devices so you may be out of luck. A BIG mistake in my opinion......
Yeah I don't see any section with RF drops but the only packet loss I seem to experiencing are with the comcast addresses on PingPlotter Pro. Can you think of a reason I would be losing packets this severely only to comcast labelled hops?

It starts right at the second hop which is the CMTS (Cable Modem Termination System) at your local Comcast headend facility / building. It could be caused by a few things like noise ingress in the upstream channels / return path or a capacity / traffic congestion problem.
Check your network cable to see if it CAT 5E or CAT 6 and is in good condition.
Also make connections are negotiating at 1Gb when you plug it in to your switch or router.
Really need a next step here, this intermittent connection is killing my small business, I have worked with computers for over 15 years and this is something I've never seen before, I replaced everything possible, from the network card to the router to the cables, tried new settings and just about everything possible on my end, at what point does a tech come out and replace the wiring so that I can get the signal I pay for without constant drops every hour? This isn't new with everyone being at home, this has been going on for months and all the techs can do is come inside and tell me nothing is wrong, without ever taking the time to look at a box or the wiring itself coming from the street. What do I have to do to make that happen? I have a neighbor installing cable and moving in my building TODAY so I'm guessing they will be getting an install. Is it possible to try and line that up with checking my wiring?
