Cm1200 slowdowns on a regular basis
HARDWARE:
CM1200 (Firmware V3.12.03)
TP-Link Archer 1500 (Firmware 1.2.0 Build 20210421 Rel. 64516(5553))
Xifinity Gigabit Cable (1200 down, 45 up)
On a normal day on my wired PC connection I can get up 1000 down with 45 up. However, every few days my speeds dip down to 30-40 down. It requires me to manually restart my Modem to get my speeds back up to the normal speeds of 1000 down. I do NOT have LAG enabled, and tried to ensure that all of my firmwares are up to date on all of my devices. I'm not sure what else I can do to try and get my speeds to stay as fast as possible regularly. Any help is appreciated, thank you.

Test the speed with out the wifi router in the mix. Connect a wired PC to the modem and speed test there.
Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.
