AP 345 random interruptions during streaming

    Hello all.

    Will try to explain this as clear as possible in hopes this can be resolved.

    Started noticing twitching and audio\video lag while on 345's wifi.

    Steps to reproduce: Connect over RDP\nomachine\teradici (basically ensure video streaming scenario) to another device, leave it on 60 fps video playback so you have a constant stream of data (video + audio). 10-15 mbit\s in my case, depending on what's on the screen at that moment.

    Randomly both video and audio will either freeze, or stutter and cut out for a few sec. This can happen good 2-3 times in 1 minute. VERY annoying.

    Why i'm pointing fingers on my AP345:

    I have 2 linksys EA6500v2 (10 year old wifi 5 routers) acting as dump APs, and no issues whatsoever while connected to either one. Butter smooth.

    Disabling my linksyses and connecting to 345, i get the choppiness.

    My 345 is in dual 5ghz mode, or this is where I'd like to keep it.

    Changing it to dual band doesn't help.

    Forced client to be the only device on either of 5ghz radios didn't help.

    Channels are not congested, I'm far enough from my neighbors to enjoy a butter smooth 5ghz stream from my old limksyses.

    Running openspeedtest or iperf, i should be getting about 620 mbit down and 550 mbit up basically straight line with 1 device connected to my 345. Sadly there's a lot of deviation.

    The rest of my network shouldn't be a problem since i run gigabit and wifi is only capable of saturating 640 mbit max.

    Please help.

    Hi, which version of Code are you running?

    Did you enabled Optimization of Broadcast and Multicast Traffic?

    Could you please paste Configuration here.

    Latest available build for 345 - LSR (Digitally Signed - Production Build)

    Multicast filtering > disabled

    Multicast transmission optimization > off

    Dynamic multicast optimization > off

    DMO channel utilization treshold > 90% (unchanged)

    ^ Multicast related tweaks shouldn't play any part in this shenanigans. Even if i push 15mbit of video stream over wifi (and nothing else), this still keeps happening.
