Wifi Outages

I have had Comcast/Xfinity for 2.5 years and have been satisfied with it until lately.  On 07/21, my wifi was down from 2 pm to 5 pm.  But on 07/22 I had outages at 6 am – 6:10, then 2 pm – 4pm and again at 8:30 pm to 9 pm.  And my rate was so slow that I could only have voice on a Zoom session and not video.  I am posting this because I wonder what is going on.  There were no storms in the area.   I have not gotten a newer box since I joined.  I hope things improve.  Kay in Normal, IL
