    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    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

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    Another update: Still running stable today, some two weeks later. It seems quite likely that the solution to these problems is to flash 384.3 and adjust the settings as I did (per advice here in this thread). Something appears to be wrong with all future versions of the firmware for now. I'd...

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    Here's my quote from earlier explaining what I changed: [Runnng 384.3]: 2.4 GHz channel width is still set to 20 MHz; the only other thing I've done differently this time is to disable MU-MIMO and enable Reducing USB 3.0 interference on 2.4 GHz as well. We shall see what results.

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    Just a progress report as promised: After making the previously-detailed/prescribed changes, I've been running the router in my environment without any reboots or modifications since my last post here (10 days ago) and have not yet experienced any issues. Nothing else has changed (and I still...

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    All right, I've swapped it back into production now running 384.3. Did an initialize and set everything up again. 23 clients connected total currently, various interfaces. 2.4 GHz channel width is still set to 20 MHz; the only other thing I've done differently this time is to disable MU-MIMO...

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    Is it possible to flash a new RT-AC86U back to 380 firmware? Apologies for the ignorance, but tech consulting is a lot like medical science you know; we're good at our areas of expertise but only tangentially useful in others ;-) Thank you! Edit: Looks like there is no 380.xx release for the...

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    Perhaps MU-MIMO is the reason. I have all of the other settings configured as suggested already. When I have a slower moment I'll swap out the routers once more and see if it helps at all.

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    Yeah; that's the version I'm running on the old 68U. It's never given me any issues and I'm reluctant to make a move as a result of that.

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    Hello everyone, Well, I recieved a replacement unit today, and it may be hard to believe, but I'm still experiencing the exact same puzzling behavior -- seemingly regardless of which firmware version I choose. What happens is that the router operates normally (quite admirably!) for a few...

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    You guys have been extremely helpful -- I truly appreciate you taking the time to reply. I will order another 86U for now and attempt to swap out (using 384.4_0) while the 68U is still working well. If this one also gives me issues then I'll return it and stick with the 68U perhaps until later...

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    Really appreciate the replies guys. If you don't mind my asking, roughly how many wireless clients do you run on average in these environments? I think mine is between 12 and 15 2.4 GHz clients on average at any given time. If no one else has seen such issues, perhaps I'll simply order...

    Any known issues regarding AC2900/RT-AC86U 2.4 GHz radio malfunction?

    Hey guys, First post here (done plenty of reading -- hopefully enough). Around 2 weeks ago I replaced my older RT-AC1900/AC68U router with a new AC2900/RT-AC86U router and immediately flashed the latest stock firmware followed by Merlin's latest (384.4_2). The behavior I encountered was...
