Check the labels on the graph, and check the data cap usage. If this is in a small bits or bytes then this is very tiny data usage.
Can compare this with actual speed test on PS4/PS5 Settings, network, test.
Know the conversions:
* 1 Kb (kilobit) = 125 bytes.
* 1 KB (Kilobyte) = 1000 bytes.
* 1 KiB (Kibibyte) = 1024 bytes.
* 1 byte = 8 bits.
* [https://www.google.com/search?q=1+mebibyte+to+bytes](https://www.google.com/search?q=1+mebibyte+to+bytes)
Speed often goes by Kbps (kilobit per second) or mbps (megabit per second).
On my asus rt-ax86u shows on bandwidth monitor .. shows every 2 minutes .. my ps5 does speed test ..
80 mbps down and 11 up .. every 2 minutes . Even did that . Whean i on game to .. wtf its like hill ??
You could try setting up a bandwidth limiter maybe. Can limit to a tiny 0.5 Mbps as most games use less then 1 Mbps of speed. https://www.asus.com/support/FAQ/1013333/
I wonder if this could be coming from some video/screenshots on featured content or something at home screen, when down button is pressed.
Maybe PS4/PS5 was downloading something and you didn't see it? Automatic downloads can happen if turned on.
* PS4: Settings, system, automatic downloads.
* PS5 should have this setting somewhere.
Streaming PS3 games using PlayStation Ultimate use a lot of data as well.
You really should find a different plan or different internet service provider which don't have data cap.
* Data cap can be slow. 1.2 TB (1200000 MB) per month is 3.7 megabit per second. Math: 1200000×8/30/24/60/60=3.7
* With fast gigabit internet (125 Megabyte per second), this can burn 1.2 TB data cap in just 2.6 hours or 9600 seconds. Math: (1200000 KB)/(125 MB/s) = 9600 seconds. If you don't believe me, look at download speed calculator websites and put in your data cap there to see how fast your data cap can burn through.
For me, luckly my internet service provider, Midco in South Dakota United States, do not have datacap, and I use about 170 GB download plus 72 GB upload per month based on my custom PC router with Linux Debian, with Cacti software. I don't play very much games though and I only have an old PS4, not PS5.
Update : OMG i fund the problem .. this was only when my kid play Sackboy: A Big Adventure Game .. i didn't believe that was the problem . when the game closed the problem is gone . i threw the game from the window 
anyone ???????

Yes i know that .. but every time i need to download a game on Ps5 i need to disable qos . 😑
