Glad to hear that helped you. There are lots of options on the router, making them all really visible would be quite chaotic and wouldn't be very user friendly or appealing to use. It is an advanced option though which is why that specifically is hidden behind a toggle.

Great to hear that! So bufferbloat/lag occurs when your connection speeds are being used fully - this happens when doing a download for example and for lower speeds like yours this can happen more often even if a download isn't happening. By reducing your speeds by 20% in this case it prevents your full speeds being used and thus prevents the bufferbloat/lag from occurring.

You need to setup Congestion Control in Ping Optimizer > Advanced to prevent that happening. Try 80% for download & upload while set to Always and try again.
