@Kevin_Z Yes the device I have it turned on for is my PC. The image shows just my QoS settings page which was mainly just to show how vastly different it looks from all the support manuals you can find on the official TP-Link website regarding my specific router. I understand that you update things but you also need to do update the manuals then because I'm unable to perform what I wanted which would be possible in the previous versions.

https://www.tp-link.com/us/support/download/archer-c7/ Like the User guide on that official site

I am wirelessly connected though and if I'm able to set bandwidth limits for devices through the DNS server settings than yes please help. I can link more images if needed but again my settings differ vastly from what that user guide I linked above shows me because I did attempt this route as well already. From the 3 devices you can see connected in the image I originally linked that shows my QoS page I'm just trying to set a bandwidth limit on LeCharles, something like maybe 8-10 Mb/s

@Kevin_Z where did you read that QoS is 'similar' to bandwidth control?

QoS is for prioritisation and Bandwidth Control is for control the limit, there is a huge difference and use cases for both.

Why would you remove such basic functionality as Bandwidth Control? It seems that at certain point the firmware was allowing it, why not bring it back?

Unfortunately just bought the Archer C7 and I regret every second
