Have a run through this guide and see if it's able to help you get higher speeds:

With QoS disabled internet speed is normal, if I turn on again my speed go down again

That makes sense, more processing is required when using QoS, DPI etc. Are ALL devices connected to the R2? 

[David marin]

Yes, I connected everything to the R2

[Netduma Fraser]

Okay great, make sure the ISP router is in modem mode or has the R2 in its DMZ and you'll get the best speeds through the R2 that is possible. You can also disable the protection options in WAN Settings and that will boost the speed slightly as well.

Okay

I will try tomorrow

the isp modem is in a modem mode but I will try DMZ because I will like have QoS enable

No need to do DMZ, in modem mode it already passes all traffic straight through to the router. It is unlikely you will get max speeds with QoS also enabled.

Then it’s better have the QoS disabled?

If you want to have full speeds then yes, given your speeds as well it will be harder for bufferbloat to affect you so as long as you don't have any downloads happening while gaming you should be okay!
