No error codes, however I used the mouse cursor and hovered over my connection status in game and I seem to fluctuate around 500 sending while traveling, but as soon as I enter combat via open world or duty finder, the sending plummets straight to 0 and ranges from 0-100 the entire time. When I exit combat, it goes back to around 500 again, receiving remained pretty consistent.

I only use one main character, happens across multiple jobs and I've been playing around 6pm-11pm. I've restarted the PlayStation-5, power cycled the modem, but to no avail. First time this has happened in the 9 years I've been playing.
