I have the exact same problem in Santa Cruz, CA. A few months ago upgraded to Arris SB8200, we the 600 Mbps service plan (upgraded from 300 Mbps). Unfortuantely, a service tech that came a few weeks ago informed me that 400 Mbps (300 realized) is the most we can expect in our area until they install fiberoptic. The 'upgrade' only cost a few tens of dollars more per more so I'm loath to downgrade, hoping for the best bandwidth possible despite the local infrastructure limitation. Typically I see a max of ~180 Mbps download speeds on my mid-2011 MacBook Air, up to 300 Mbps on my two year old iphone 10 and up to ~280 Mbps on my 2019 MacBook Pro laptop. Starting a few weeks ago, I find I have to reset my modem EVERY MORNING or sometimes more often, otherwise speeds go down to 2-5 Mbps. As others on this thread have noted this is VERY frustrating and has me wondering why I don't just switch to AT&T. If Xfinity doesn't get it together soon, I probably will switch. We have 4-5 people in our household attempting to work and attend school remotely. These resets seriously compromise our ability to make a living and educate our children. Considering the amount of money we (the greater community) are collectively paying Xfinity, they need to fix this ASAP.
