Orbi 772 slowing ALL my devices to less than 200mbps

Hello everyone.   I have my Orbi 772 system installed since last week, and the experience is being horrible for my 4th Orbi. By far the worse.   As a starter, there is anything I can do to fix my...

    Hi plemans!

    First of all thanks for your reply!

     

    I am glad to share that I figured out what happened, but will first answer your questions.

     

    1.I know you said you're on the latest firmware, but what actual version do you have?

    V10.5.13.1_2.2.34

     

    2. what modem/gateway is it connected to? 

    - It is connected to an Askey modem (I’m in Brazil)

     

    3. you won't hit faster than 200mbps over 2.4ghz. I'm impressed if you're actually getting that. the 5ghz yes. 
    - Actually I was at 6ghz, my mistake.

     

    4. Might try reinstalling the firmware (in case its corrupt), factory resetting (I know you already did), and then reinstalling fresh and not from a backup (in case something in settings is corrupt). 

    - Tried, didn’t worked out

     

    5. Try testing the speeds without the satellites connected. 

    - Same results

     

    6. Is ipv6 enabled?

    - BINGO! Will better explain below!

     

    7. what app/speedtest are you using and whats hosting it? 

    - Netflix “fast.com”

     

    8. what hardwired speeds do you get?

    - Same 200mbps

     

    As it turns out and long story short, my problem was related to IPv6! 

    I was really convinced that it was related to Double NAT, because when I put the modem in bridge mode it solves all issues. However, leave it in bridge mode is not an option as it disables my cable decoders. I called my ISP/cable provider and made them replace the modem, and I even changed some advanced configurations to try to have the internet in bridge and keep the tv working, but I have lost all interactive options for the TV.

    Then I decided to turn on my 963 and check all options in every single menu, and I found out that Netgear started to ship the new devices with IPv6 on by default and on pass through mode. This was making the Orbi device correctly assign the IPv4 address, but acquiring the IPv6 address from the modem as its router. When I’ve turned off the IPv6 all started to work flawless like magic.

     

    My final message to Netgear in this case is to better disable it again on next firmware update by default, and if someone needs IPv6 they can enable it by themselves. 

    Thank you for the ideas and support, plemans!
