Frequent Slowdowns on Gigabit

Been having intermitent speed issues since day 1. Speeds will be within acceptable range and then DROP HARD to 30mbps download, but upload remains unaffected sitting right at 40mbps. It will remain this way for hours/days.

 

Speeds are consistent between ethernet/wifi. Tried running directly into modem with no difference.

 

I had a tech visit scheduled for this morning but sadly earlier this week my girlfriend had a work exposure to Covid and now we're on quarantine for the forseeable future. Can a tech just come and check the lines without having to come in and confirm that both modems I own are both operational? Now that we're both stuck indoors nearly 24/7 having unstable/unusable internet is pretty rough. Tech support has been mostly a waste of time just having me reset my modem over and over and asking redundant questions. If I'm only getting 3% of my advertised speed I find it ridiculous to continue to pay my full bill with no way to amend the situation.

 

These speed drops seem to match up with many other user's issues which almost always end up being line issues. What can I do?!?

Running an Arris SB8200 and Netgear R6260 (AC1200).

Seem to be losing one channel completely. Again, completely random. It will be hot, cold, dry, wet, day, night; doesn't matter.

It is the SB8200. I had similar issues with my network speeds. I have had to reboot the modem daily. I replaced it with a Netgear CM1100 on Friday and so far the gigabit performance is solid.

Re: Frequent Slowdowns on Gigabit

I have a second modem that I've used to troubleshoot, a Netgear CM500. The Netgear will encounter the same slowdowns. Channel status is also a mess and the event log is also filled to the brim.

 

Had a few hours late last night with acceptable speeds, right back to 35mbps this morning.

 

Also to clarify, rebooting/hard resetting the modem makes no difference. Simply have to wait it out...

 

Had a chat last night with customer service/tech support and they assured me they'd have someone come out and check the lines but hurried off without giving me a date or timeframe... So I'm left waiting in limbo again.

 

Here's the channel status from the SB8200 this morning. https://imgur.com/a/pXPHecP
