Upload speed randomly dips throughout the day

Hello,

For the past few months, my upload speed has been fluctuating from its maximum to around 40% of its capacity. This is most impactful during while I am streaming using OBS to YouTube as frame drops occur during this time, though the issue is not YouTube/streaming specific - the bitrate that I stream at (15Mbps) does not approach my expected maximum either (100Mbps).

I recently upgraded my package to Gig1 and replaced the Hub3 with a Hub5, but the problem still persists. There doesn't seem to be a specific cause, and my download speed remains stable during these periods.

Wondering if I could get support in this matter.

Here is a link to a live BQM (EDIT: Updated since going to router mode gave me a new IP):

https://www.thinkbroadband.com/broadband/monitoring/quality/share/aff97055f476476894b35dbdaf4bf837c2...

Posting network status data from my Hub5 in the next post.

My upload speed has dropped by like 70% ish over the last 5 days or so. On a 1gig connection gone from 110-100meg upload to 30-35meg also not only that the packat loss is terrible as well now since this started.

Wanted to bump this with the fact that this issue still occurs in router mode, and regardless of the Ethernet cables I use to connect my devices to the Hub, so it is not an issue with my usual setup.

Since going back to Modem Mode returns my previous IP (and I can no longer edit the original post), here's the link for my BQM while in Modem Mode:
