Internet speeds dropping and wifi shutting off several times a day
So i just moved, after setting my internet up i noticed the wifi shut off, running a test in the app told me my speed was ~15% of my plan's speed. After restarting the gateway the speed picks right back up and the wifi turns back on. This has been happening several times a day since. The event log on 10.0.0.1 doesn't seep to record anything happening so i don't have much to go on.

The issue i was experiencing was caused by a bad modem. Seems the modem would slowly heat up over time and seems like it partially shut down because of it. Having swapped it out i haven't had any issues for a full day!

This may or may not be the root cause of the problem (YMMV) but it should be addressed regardless. The downstream power levels are too high / out of spec.
That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.
Is there a drop amplifier on the coax line leading to the modem ? If so, try removing it and see. If not, you can try installing a -6 dB forward path-only attenuator pad such as this one on the coax port on the rear of the modem to knock that power level down and see. You may need to use two of them piggybacked together for a total of -12 dB loss to get that power as close to 0 dB as possible;
https://www.amazon.com/FPA6-54-Forward-Attenuator-DOCSIS-Internet/dp/B08KTRC3XZ
It won't affect the upstream power level which is within spec. Good luck !
