RAX-48 Internet dies once a week

Once a week my xfinity internet dies on this router. I log in and reboot 192.168.1.1 and it comes back. It always show internet Status:GOOD. But it's not.

So I try to look in the logs and I noticed all activity for the day is gone.

I have it sending a daily email. 

For yesterday

Mar 30,2021 00:41:40 THRU Mar 30,2021 22:52:31

But the log it sent today shows

I logged in one to reboot it becuase internet died. 

Why is it showing last year. 

I am starting to think this thing is defective. 

Under LAN setup it refuses to store device names, no matter what I enter for some of the devices.
