Nighthawk XR1000 Bufferbloat high

[JA23]

I just got a XR1000 and was working on it all day to try and make it run right but im getting anywhere from 100 to 200 less download speed and my download buffer bloat is higher than my isps router/modem when i abled qos it made it worse does anyone know how i can make it so my download bufferbloat isnt so high? its alot worse than my isp provided router

what modem/gateway is the XR connected to? 

What speeds do you pay for? 

What speeds do you get hardwired into the modem/gateway?

Where are you testing the speed and bufferbloat exactly, using Connection Benchmark? If so we are still improving on the reporting from the feature so you can take the results with a pinch of salt.

[JA23]

I’m using waveform connection benchmark and I tried using dslreport but for some reason it hasn’t been working with my xr1000 connected

[JA23]

My XR is connected to the xFi Gateway 3rd Generation, I pay for 1000 download and usually get around 940 when plugged into my isp provided router/modem but on my XR get in the 700s for download upload is good though same thing with my bufferbloat only download is bad

[plemans]

Is the router's IP address entered into the xFi's DMZ? or is the xFi in modem only mode?

[JA23]

It’s acting as a modem only I put it in bridge mode

[Netduma-Liam]

If you completely disable QoS from the three-line menu in Congestion Control, does this improve the speeds?

[JA23]

yes Ive had Qos disabled because having it on didnt change anything for my bufferbloat etc

[Netduma-Fraser]

So you get your expected speeds with QoS disabled completely? When you don't get your speeds with QoS enabled what settings do you have? You won't be able to get rid of bufferbloat without using QoS, also bufferbloat only occurs when the connection is saturated and given your speeds that is unlikely to happen.
What QoS settings have you tried specifically and can you provide a screenshot of your test results?
