Internet Problems Every Morning . . . .

I haven't had any internet problems in a long time.  But this week, always during morning hours, my connection keeps going from good to very good.  Now, with my Gateway, very good is the kiss of death.  That means it will look like I have internet and my eero 6 will show I do, but I don't.  Then the eero light goes orange.  At no point does the Gateway not show 5G internet connection.  Unplugging the Gateway and then unplugging the eero works only for a short while.  It goes back to working for so many minutes and then back to not working.  Currently, it's working as I type this post.  I think it's something like the tower signal, not anything I can do. What do you think?
