It seems like I can't set the main QoS engine bandwith on DIR-842. Every time I click save, the page just loads but nothing's changed. Also no 30 sec timer.

Btw I just want to limit this router's global speed since this house only got rm79 basic with 60gb data cap.

It was working before though. Managed to make up/dl speed to 2 mbps each from 300 mbps (original). Tested max download, and it stay 2 mbps, then I change it into 30 mbps to test back if it messed up the system.It was the last time it for to work.



Now I can't even change it back, up speed is still shitty 2 mbps.
