Frequent Download Speed Drops after upgrading to Gigabit X2 Plan

Ever since upgrading to the Gigabit X2 plan, I’ve been experiencing frequent drops in my download speed multiple times per day. This issue didn’t occur with my previous plan, and my modem (Hitron Coda56) was functioning without any problems before the upgrade.

The speed drops seem to occur at specific times. For example, I noticed them around 11:00–11:30 PM yesterday and today, as well as around 1:00 PM today. Not sure if there is a misconfiguration due to the higher speeds. Restarting the modem fixes the issue but i do not want to be doing this since prior to the plan change i was not required to do this so often
