When the speeds drop, do they resolve on their own or what do you do to fix it?
When the speeds drop, what do the logs show?
Thanks for your reply.

- I tested it out on my PS4 Pro, none of my laptops have ethernet ports unfortunately.
- Plugging directly into the modem produces the same speeds as the router. It's a Linksys Router (AC1750)

- I went to sleep one night and it was better in the morning (so I assumed an outage), but down again at night. I haven't found a workaround that works yet.
When the speeds drop, what do the logs show?

I would test with a PC or laptop with a LAN port. Game consoles are not the most accurate in reporting speed results.
Have the ISP check everything from there side up to the modem.
