Router capped at 100mbps

Hello. I've had this problem with a couple routers before this one, so I'm hoping someone could help with my issue. We pay for gigabit fiber internet and we do sometimes achieve those speeds. But a lot of times the internet goes back to being capped at 100mbps. And it's not just through ethernet, every device connected gets the same speeds. As for the "modem", there is none. It's a cable that has a coupler on it which I connect one end of an ethernet cable to and the other to the router. And I also have an access point which is my previous router (Archer AX11000). Again these issues happened with a couple router before my current one.
Things I have tried:
- Updating router firmware on both the router and AP
- Connecting an ethernet cable from the coupler to my PC to check speeds (which are at target gigabit speeds)
- Trying 10 different ethernet cables ranging from cat 5e to 8
- Changing the WAN port speed to 1000m Full-Duplex, as well as every other port.
- Unplugging the AP and using only the router
- Calling my ISP for help
I'm not sure what else to do.
