Download speeds: great! Upload speeds: abyssmal... :(

Using a MB8600 (an approved 3p Docsis 3.1 modem). For a long time (in the tune of years), I was getting about 10-12Mbps upload on my current plan.

This past week, I'm averaging most of the time around < 1Mbps (like 0.3 - 0.5).

As a gamer and a WFH employee, I need my upload speeds back...😭

Troubleshooting performed:
- Reboot Modem

- Reboot router (just in case; download speeds are in fact, just fine)

- changed wireless / wired

- tested during various times of day and night

- No listed outages

- tracert capture was inconclusive but it did seem to "struggle" the most between my router/modem and the next few hops along the way to UW (picked somewhere close)

(EDIT: I'm about ready to submit this and a final speed test gave me 11Mbps peak for upload... 🙄)
(EDIT2: And back to <1 Mbps)
