RBK753S - Much slower wifi speeds after AUTO firmware upgrade to 3.2.18.1! 3.2.17.x was MUCH faster

I had intentionally downgraded my RBK753S from 3.2.18.1 to 3.2.17.x and with 3.2.17.x, everything was great! But this morning I noticed that my firmware updated automatically to 3.2.18.1, which seem...

    Quick update - Since I am / was experiencing the low speeds noted above (330 - 350 Mbps), I just disconnected and reconnected my Netgear A7000 wifi adapater from the network in Win 10 (did NOT unplug it).

    After reconnecting to the network, speeds improved to 430 Mbps on first run after reconnecting, then 471 Mbps, 476 Mbps, 468 Mbps, one slower one of 451.7 Mbps but much better than before the disconnect/reconnect, and then 470 Mbps.

     

    Will monitor stabilty after a few hours and also after a full day or two / after restarts / hibernates/ shutdowns etc.

Did you power OFF the RBR and RBS for 30 seconds after the update or factory reset and setup from scratch? 

Something to contact NG support about and let them know.

    Thanks.

    Unfortunately, I could not power off and restart the router / satellites yet since that takes too long given I was working and on a call and wife is on a call now. A quick adapter disconnect / reconnect right after my call was less intrusive.

     

    I can try when we are both not actively on calls / responding to emails etc.

     

    In the meantime, will run some more tests...

      Very happy to report that for now, wireless speeds have stabilized, ever since the 10:24 AM test I referred to above. Also no wifi connection issues (tested using my Netgear A7000 USB wifi adapter).

       

      The true test, based on my prior experience, will be seeing how it holds up, in terms of continued stability, over the next day or so...

      So long as speeds hold up and I have no disconnects the next day or two, I will consider this 'solved'.

      My plan is 400/10, but as you can see, I am getting almost 480 Mbps wirelessly.
