Its been a continuing issue I've been having as you describe. It gets mentioned occasionally on the OpenWrt forums... but never seems to get a critical mass of attention. I and others have started threads, that have faded out over time. Now, it seeming that a general thought is developing that "C7's just arent good for 2.4ghz" hiding that they WERE, and now have an issue. Anyway, even though I'm mostly a lurking layperson.. I have lots of collected logs over time, and have lots of observational data on this issue. Not much in the regular logs, though. A while back in history it was more the 5ghz radio dropping, but in the last several months to a year its been almot always the 2.4ghz radio, similar to what you are describing. I would like very much to know how to find out the necessary info so that the devs can get a handle on it.

Dave, You are not the only o= ne noticing widespread wifi issues, and I=E2=80=99m beginning to think some= thing is amiss in the core 80211 or related code, as ever since 18.06 (and = up to recently released 19.07.4) I=E2=80=99m observing issues with sensitiv= ity to congestion, drastic decreases in throughput at distance, and on MT76= , very frequent =E2=80=98drops=E2=80=99 of network connectivity, yet statio= ns remain enrolled and show good signal levels. Sometimes if comes back in = 10 seconds, other times minutes. And often, a restart is the only answer.
LEDE 17.x had very good Wifi on the Archer C7, then 18.x = and 19.x are nowhere near as good, especially on 2.4.

<= div>Current 5.x Master looks better on Mt76, but still see some issues.

A shame, as when the units are operating, and one is = reasonably within range of 5Ghz, the throughput and low-latencies are quite= good.

Are there any guides on how to gather relev= ant stats to help document these issues so the devs can zero in on the prob= lems?

Cheers,

Jonathan
