CBK752 Bufferbloat

Hi,
Just wanted to know if anyone else was having crippling Bufferbloat with their CBK752 modem / router. Causing me huge latency and very unstable streaming (twitch), have tried everything I could but seems pretty hopeless. Guessing it's a firmware issue? Can't seem to get the hidden qos page to do anything, and have tried a factory reset with no speed test to try to turn off all qos but to no avail

Cheers,
Richard

    What Firmware version is currently loaded?

     

    What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
    Any Wifi Neighbors near by? If so, how many?

     

    Try disabling the following and see:
    Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).

      Using firmware V3.2.16.9, connection is wired so I'm not sure changing wifi related settings should have an impact, right?

        Didn't know your having problems on wired connections. 

        How is your device connected? Does this device have a ethernet port? 

        Be sure your using good quality LAN cable. CAT6 is recommended. 

         

        Test streaming and video with a wired PC or laptop to compare results...
