Unstable/inconsistent speed on Orbi RBK 852 AX6000 after upgrade to Spectrum Gigabit

Hi, All -   New member of the community here.   I set up my new Orbi RBK 852 system (with two satellites) last Friday, replacing a series of Apple Airports I had been using for some time.  I had ...

    Any Wifi Neighbors near by? If so, how many?

     

    Be sure that CTS and RTS values are changed to 2346 under Advanced Tab/Advanced Settings/Wireless Settings

I guess what I'm struggling to understand is why, with a much faster connection, I would be seeing speeds lower than my old 350 at any time when I really did not before.  Also, the instability seems odd.

    Furry -

     

    I just changed the RTS and CTS values.  Will see how that works out; they were set to 64 or something like that, whatever the default would have been because I haven't touched it.

     

    We live on a corner in a typical suburban neighborhood, so there are definitely wifi neighbors but we generally have not had issues with interference.

     

    Wouldn't turning off AX mode negate the benefit of having purchased this router versus the less expensive Orbi?  Or are you suggesting that just as an experiment?

     

    Thanks.

      Yes, NG seems to have started using 64 as a new default for those values. Seen odd problems since they started doing that. Seen some problems fixed by having users chane back to the old default values. 

       

      Experiement only. I would disable it now. Then see how the system works with the new CTS values. If it seems to stablize and fix your problem, then re-enable AX mode.

        Furry - 

         

        Changing the CTS and RTS values seems to have produced consistent improvement.  I did not tinker with the AX at this point; if I have more issues I will.

         

        It also seems that I consistently get better/faster results if I use a server that is farther away for a speedtest.  I don't understand that.

      Have you tried plugging your PC directly into the modem to do speed tests that way?  That will give you a better sense of the actual operation of the incoming signal before it gets to the Orbi.  If it shows similar variations or speed ramp-ups, then it could be an ISP issue.  If it's a solid connection at the modem, then there may be some issues with the Orbi.
