So ithought my speeds were 150 down and 5 up.When i originally got the xr500 thats what all my speedtests showed.I was never happy with my settings.Today i disabled qos and did multiple speedtests.I found out my speed is 250 down and 10 up._i rentered those values in qos, put my sliders at 70-70 and my dsl reports test was the best its been.Hope this helps

Also you have to click the drop down box to see were it says disable qos.Just clicking never doesnt work and then make sure to renable it

I keep my settings higher than what it actually is. Like a my subscription says 300/300  but speedtest suggests about 340 up down so I leave then values at 350/350. Then dial that down to 300/300 in the anti bufferbloat setting.
