XR1000 bufferbloat spikes.

[sam_2991]

Hi, trying to explain my issue if solvable:

I'm on PC and I have an ISP that requires PppoE, i read many post here and i think i did everythink right. I have a Nighthawk D7000 that manage PppoE, disabled all wi-fi, ddos protection, put the local IP of XR1000 on DMZ.

On XR1000, i have these setting (sorry 4 Italy language i hope is understandable anyway) on the files, and QOS with this trick work also on upload and fine, but i have a "little issue": I have Vdsl fiber with rame

70 down / 20 up and with qos i put 58 down /17 up and many times i hit A on waveform test. Sometimes I hit B cause everytime i do the test on Upload and sometimes on Download i have a "spike" that go over 300/400 ms. There is a way to possibly avoid/reduce this? Contact ISP excluded.

I've tried TCP optimizer  some tips but only work on Download side but i remove it because i think cause hitreg problem on FPS.

I do not use Upnp, only port forward 3074 UDP for COD and disabled 5 ghz Wifi. 

disable dos protection for latency improvement and MTU 1488 (i know 1492 for pppoe) idk i  always have that on D7000 and keep ip cause work good .

For the test i reduced download on 52.5 cause ISP just hooked 60 (if i do not reduce and stay 58.1 on qos i have 60+ ping on download) but usually stay between 66 or 70 and have 20/30 ping on download.

I would suggest resetting Bandwidth Allocation, that's not necessary and then it's just a case of experimenting with the Congestion Control percentages to find what works best for you - it's individual to each person/setup so there isn't much to advise other than that

[sam_2991]

tu 4 reply. idk i've tried the application prioritizing gaming but seems work bad on fps. I'm admit that i'm a demanding gamer. On congestion control i think i found the best % for my cnxn, maybe i miss some other tips, i read many post here. 

[sam_2991]

The best tips i found for COD is priotize from UDP 3074 to 30000 - 45000. Now i'm playing Xdefiant, i'm asking if there are a similar one (i know 1-65535 both sides or 1024-65535 tried only UDP and TCP/UDP but i think cause disadvantage, sometimes bad hitreg and opponent insta-kill)

[Netduma Fraser]

Apparently it uses these for PC but don't know how true that is TCP: 13000, 13005, 13200, 14000-14001, 14008, 14020-14024

[sam_2991]

i see it on portforward.com but idk TCP on gaming is a risk. But hypothetically what origin port? maybe range between 13000-14000 where origin or destination?

[Netduma Fraser]

It's not a risk, you're not forwarding any ports, just prioritizing them. The origin port could be anything but likely to be the same as the port mentioned

ok in these days i will give a try.
