I have one of these, and I've been running a self built snapshot with basic packages on it, for over a week now, and the buffer bloat is terrible. I can sometimes get my cable Internet line speed over it, but ping fluctuates horribly.
I can ping my router, also running OpenWrt, and the ping times will fluctuate between 15 and 112 milliseconds. Do I really need to run SQM even on the AP to get decent latency?
Are you sure that's buffer bloat, and not just wifi acting weird? Does the issue happen also when there is no other traffic?
What wifi card are you using on the client side?
Are you routing or briding this AP?
Do you see tx/rx errors or pause frames on your interfaces?
Are you using exotic WPA3, roaming, or dfs [20/40/80MHz]5GHz settings?
Pinging the OpenWrt device from wifi or from wired also affected, not the router behind it? This may hint if its the wired or wifi interface in the UAP-PRO-AC...
Is there any multicast traffic iptv/streaming in your lan?
That sounds like poor connection and/or one of the ends switching transfer rates, does it affect all your devices or just some?
The WiFi client is an iPad 6th generation, running ping from iSH. It affects anything connecting to the WiFi, and most devices are at least a room away from the AP. I don't want to believe the nonsense that these Unifi APs are only good for the same room they're located in. It worked fine before I switched to OpenWrt.
It happens all the same pinging the IPv4 address assigned to the AP. Round-trip min/avg/max = 3.730 / 61.486 / 162.422 ms. This is from the next room over from the AP, about 15ft away, through drywall, with open hallway, but not direct line of sight.
Where can I check the lost packet statistics? I also noticed that the driver doesn't use a 64 bit counter for total traffic sent for a given client, so the long connected clients start to wrap around into the negative int32 space periodically.
I am using the WPA3 mixed mode, and 80MHz on the 5GHz band, and using automatic channel selection, as I can't find any channels in the listing on the interface page that are valid channels for 5GHz with 80MHz width. WiFi density in the area is fairly light.
You may be getting some overlap interference at 80 MHz. Try lowering that to 40.
You might also try the non-CT drivers for ath10k.
Okay, I'll try 40MHz, and if that fails, I'll try rebuilding the image with the non-CT drivers.
There are release and snapshot firmware images for your device...
If I use release, it nearly fills up the device updating WolfSSL to the latest version. If I use snapshot, I'll have to SSH in just to install LuCI, and risk running out of space anyway. The device has 16MB of flash space.
Oh, and this is what I see when I go to select a channel for the 5GHz interface:
36 to 48, or 149 to 161 is recommended.
50 to 144 are DFS (radar) channels in most geographic locations, and should be avoided.
you should just need to choose one of those (20 MHz width) channels even if your using 80MHz width. The driver should adjust it for you. I'd select just one channel and avoid the auto select.
i.e. channel 36 at 20MHz width = channel 42 at 80MHz width.
ethtool -S wlan0 will dump a bunch of rx/tx stats not sure what that poster is looking for specifically. ifconfig might be enough.
I can't get ethtool -a wlan0 to show me paused frames.
Since your using ath10k... just for fun, try testing with one and only one client connected. Then add clients one by one and see what happens. I totally believe that the AP will only be good for (multiple) 5GHz clients that are in the same room as the AP as I experience this every day on a r7500v2 (qca9980 not your qca9880).
If you really want to see something awful, try using multiple 5GHz clients with no line of site to the AP say 30 ft away to iperf/netperf to a server connected to the AP. i.e. stream data from more than one client to the AP which is then connected to a iperf/netperf server(s). Then try the same thing with the clients in the same room as the AP. The higher the clients speeds under ideal conditions the more likely it is for me to observe that client grinding to a halt during a netperf from a challenged location when it is competing with other clients. When it's the only clinet doing a netperf, it's generally fine.
I downgraded to 21.02.2, and the problem went away. I'm going to guess it was something I misconfigured in my personal build.
If your problem is solved, please consider marking this topic as [Solved]. See How to mark a topic as [Solved] for a short how-to.
This could be caused by memory usage from unrelated apps you include in your build.
FWIW, I am using a couple of Unifi AP AC Pro's which I regularly update to current master. The work perfectly. But I gave up on the OpenWrt default ath10k driver/firmware a long time ago (sorry, Ben). There were just too many unexplainable issues which, to my untrained eye, looked like some sort of resource starvation. I realize that this is a fine balance between features and stability on a system like this. But to me at least, the non-CT ath10k driver appears more stable.
Some typical log events from before I switched drivers (in January 2020 so it's a while ago):
