Internet drops 3 times a day, same time frame (50%+ download, 95%-100% upload loss)

7:45pm EST - 2/14/2026

First off, I'm using a PC. Windows.
I have had Xfinity internet services since Feb 2023.
I pay for the 1200mbps download and 40 (50?) mbps upload.
Wired Ethernet connection to a Xfinity XB7 Gateway.
I do a hard reset (unplug) almost daily. 
I have multiple new Cat 5, 6, and Cat 8 ethernet cords to try, and two different ethernet ports (one on my motherboard and I bought a 2nd one to confirm to Xfinity that it WASN'T my hardware)
I have tried different coax cables as well...
Yes, I live in an apartment complex with about 20 other units in the building. I do understand network congestion, but there is no way that the congestion is almost 100% of my upload speeds and 50%+ of my download speeds.
I live stream (Twitch/Youtube/etc) which requires a constant bitrate upload of about 6mbps. I don't even need the full upload required for my plan and I know that other Xfinity users in my building may use some of that bandwidth.

So... Every Day, since mid 2024, after 3+ years of service with Xfinity... my internet will drop to barely usable levels. At first, it was just once a day, however that changed in April 2025. Now, I can prove that my full bandwidth drops 3 different times a day, at EXACT times and lasts until about an approximate time, each day.

I decided to take a little staycation off from work: Do some streaming, cleaning, etc.
I know that my internet likes to drop every day, 3 times a day, so I made a log of when that was happening. What I found out, was that my internet is throttled at certain times (On the dot!), the same times every day, and this throttling ends within a 15 minute window at the same times every day.

Mornings: 7:45am EST until 9-9:15am EST
Afternoon: 12pm EST until 1:30-1:45pm EST
Evening: 5pm EST until 8:30-9pm EST

Same times EVERY SINGLE DAY, recorded over 6 days. These times are consistent with the times I noticed my internet throttling for the past 2 years, but now I logged it and can prove it.
I ran some more tests. I always use speed tests by various sources, not just OOAkla or Google speed test, plus a constant Download and Upload (both individually and separately) stress bandwidth tests, like the one by StarTrinity, and Twitch's own Upload speed test with OpenBroadcasterSoftware. 
Tech info: (Averages over 1 week)
Rx Packet loss (download) > 1%
Rx Jitter: 8ms - 26ms
Tx Packet loss (upload) 6-12%
Tx Jitter: 135ms - 655ms

All of these tests, during the time frames above, I'll receive about 600mbps download (for downloader tests) and 3mbps to 0.01mbps. Sometimes the upload test simply fail and kick me offline or claim nothing was uploaded. These tests only give these results during these time frames... "Peak Times" they would say, but so peak that I can't upload even a photo to instagram without it taking 2-3 minutes?! Sometimes I can't even send a signal to the website that I clicked on a link. Online gaming is impossible during these times. You think my inputs register?!

Needless to say, I've called into tech support at least 50+ times since 2024. 
It takes 15 minutes to finally get to talk to a human, if at all. Screaming "Speak to a customer service representative" is not enough apparently. Sometimes it's an hour, sometimes never at all.
A few instances, I've spoke with what I hope was an actual human over text, which still didn't help.
Usually nothing resolves, and if so, it's only temporarily. In 2 years, I've had 1 or 2 techs come out, 100's of modem resets from both the app and the tech guy on the phone, I've bought new hardware of my own on my own dime... nothing has changed. 
The answer is always the same:
- We see no issue
- No outages reported
- It's not on our end
- It's not our equipment
- I'm seeing full internet speeds here on our end, do another speed test
- If we send a tech out and prove this to you, we're going to charge you money for it
- It seems everything is working fine now, no need for tech support
The run-around is real. 

One thing is curious, and it makes me feel like I'm taking crazy pills here... but this is where I am now.
When I call in to tech support... within minutes, of just talking, ZERO work on the phone tech's part... my internet RETURNS TO NORMAL.
Full upload and download. No issues the rest of the day. However, the next day, the internet is back to the same drops.

So I decided to test this theory today. 
7:07pm EST
I called tech support from 1-800-Xfinity. I was hung up on by the Autobot 3 times when I was asking to speak to a customer service rep for tech support... 
They restarted my modem twice.
They finally said that it would take 31 - 76 minutes to speak to a human. I scheduled a call back as I was not going to wait that long.
Ended the call around 7:20pm
At 7:21pm... The internet fully returned.
I [Edited: "Language"] you not.
1 minute after I hung up and the internet just works?!
Remember, I'm within that time frame of the internet being throttled, full upload and 50% or more of the download... and my internet just works.
I feel like a schizo, and I didn't want to be gaslit by Tech Support telling me "everythings looking fine here"... so when the Xfinity autocaller called back to get me on with tech support, I didn't pick up the phone.
Internet is still going strong right now, as of 8:21pm, still within that window of throttling...

I feel like I'm being messed with. This can't go on anymore. Do I need to call in every day to complain at 8am just to have good internet all day?!
Because that's what I'm about to do until this gets resolved or I get refunded for months of loss. Who needs to use the internet only at 10pm to 7am?!?!
Xfinity, please advise, fix this, or make me whole. If I didn't need internet, I'd have dropped my service with you by now. I'm no longer under contract.
