    I've been having these issues with my RT-AC3200 running the latest Merlin firmware. I tried some of the fixes suggested here and will see if they help. One fix I haven't seen mentioned on this thread that I've read elsewhere is to put all 2.4ghz devices on a guest network. Has anyone tried that?

    Yes, I believe that it worked for me. I just didn't wanna run it like that forever.

    So, just curious: has anyone been running any of the newer firmware versions (with lots of 2.4 GHz stations/clients) without issues? This has to be fixed by now, right?

    Should I just remain on 384.3 for eternity? ;-D

    I also had issues with my RT-AC86U, after about three months of working without issues (AP mode) it stopped sending DHCP to 2.4GHz clients so they wouldn't connect correctly unless they had a static IP. Ended up sending it in for RMA and they sent back a new/refurbished unit. All working for me now again.
    For reference I tried multiple Merlin builds, and stock firmware with the same results.
    Might be a hardware problem for some of your issues.
