Daily Slow Upload Speeds...

Hello,

I have tried a thousand times to get through the automated system and while restarting my modem works as a temporary fix, the issue still persists DAILY. Every day, around 10:45a-12p, my upload speeds will slow down to 0.1Mbps and it affects all of my devices. My work laptop(connected to VPN for work), my personal PC(no VPN, but network extender), my husband's work laptop(connected to main modem via WiFi). This is not working for me because we both work from home and our jobs are production-based. This interrupts my ability to do my job and puts me at risk for reprimand or worse. Restarting my modem every day should not be expected.

I did talk to Xfinity multiple times via chat, when I could get through. I was told that my modem was an older model, so I went to the Xfinity store and got the X8b model yesterday to see if this would solve my issues. Unfortunately, it did not. Today, at 10:45, my upload speeds tanked again and my download speeds were cut in half, and I could not get any work done. I had a tech appointment set up for Monday to see if someone could come check the wiring around my house, but the system automatically cancelled it because my systems were "fine". Of course they are fine at every other part of the day, but not during the most crucial time of the day. PLEASE someone help me! This is getting on my nerves not being able to talk to someone when the system can't actually diagnose my issue.

Edit to add: I am on the GIGABIT EXTRA plan with upload speeds of up to 35Mbps(but I actually get about 40). My personal PC that is hardwired into my network extender usually gets anywhere from 600-700Mbps, and the PS5 hardwired into the modem gets around 860Mbps. I noticed the issues beginning last Friday, May 2nd, but they could have been going on for longer, just not to such an extreme amount.

Thank you in advance.

FINAL UPDATE: There was an issue at another telephone pole causing issues with our internet, likely damaged from a bad storm we had a few weeks ago. Xfinity techs got out here pretty swiftly and fixed the issue. I have to wonder if any of my neighbors were also experiencing issues on their end, but now they should not be. :) My upload speeds are stable and I'm noticing no speed issues while doing my job.

Thank you for reaching out and making a new post. As someone who works remotely, I can imagine this has been very frustrating to deal with. I did check the equipment and power levels at the home, which appear solid. Based on your post, it may be possible that the troubles may be stemming from outside the home. I'll jump in on my end to help review this further.

We checked the seating of the coax cable just to be sure that wasn't going to be an issue. I hardwired my PC into the modem and got way better download speeds, but the problem of intermittent really low upload speeds happened once more today. Xfinity Support checked the signal to my modem and noticed there was "interference with the incoming signal and outgoing signal-to-noise ratio" so they are sending a technician out on Friday to check the lines to my house for damage. I'll update more within this post after the technician visit.

Edit to add because I did some research: Interference with the incoming signal and outgoing signal-to-noise ratio(SNR) usually means there is a physical or electrical interference problem. Examples of interference could be: damaged cables, electrical interference from a microwave, phone, or other type of device that emits waves, faulty modem, bad weather, etc., which is why they are sending a technician out to check the physical wiring as we have already replaced the modem and reset the coax cable inside the home.
