R8000 causes slow internet

If I plug directly into the NBN provided modem (Arris CM8200B) with a network cable to use a Hybrid Fibre Co-Axial (HFC) technology connection, I am able to receive 28.73Mbps.  If I then disconnect and reconnect via the Netgear R8000 again with a network cable I can now only receive 4.04Mbps.

 

Suggestions please.

 

Cheers :smileyvery-happy:

    Thanks Aspirant, the issue is with wired, not wireless, and the solution seems to have been to disable QoS.  We are now up to a Line Speed of 42.56Mbps and Download Speed of 5.32Mbps on a 100/40 connection.  I understand it should be up towards 80Mbps, however this can be due to cable connections that are over 20yrs old.  At least I have had a vast improvement by disabling QoS.

     

    Cheers  :D

    I have found that by turning OFF "Enable Dynamic QoS" I can get a speed boost to Download Speed: 13.99 Mbps and Upload Speed: 5.24 Mbps.  There must be other settings that can be disabled to have more throughput.

    Disable QoS, access control. Make sure that the enable 20/40 coexistence box is checked in router

     

    settings under the advanced tab; I think its checked by default. 

     

    I had a significant speed drop when the 20/40 coexistence was unchecked. Btw, are you on the latest

     

    firmware? What speeds are you supposed to get from your ISP?

     

    Also, did you get a higher speed on 2.4 or 5? Check it on 5 if you haven't yet. 5 is usually less crowded and

     

    can provide higher throughput. Is there any network interference in your home from your neighbour or

     

    home devices (cordless, microwave, bluetooth phone etc)? Play around with the channel number to see

     

    which suits you best. if you have inssider app or something similar, you can check channel number used by

     

    your neighbours and then can select a less crowded channel.

     

    If your issue still persists, do a hard reset.
