So I'm working on tidying up my 11n TX code. (Yes, I > have 11n TX seemingly working.) > > Adrian Adrian, the reason for my original post (seeking to return to the BSD environs) is that we are seeing gross quantities of stuck beacons in dmesg on the Ubiquiti M series and have recently noted perps diagnosed by the UBTik (a MikroTik in a housing form fit and function compatible with the Rocket M2) trying to associate with _WDS requested_ resulting in latencies of 10x-20x normal latency. We don't run WDS on our 2.4 GHz APs. We only run WDS on Ubiquiti M5 series in PTP because that's the way they produce a transparent Layer 2 bridge. Is the amount of time spent processing such a request, combined with logging and a busy channel, perhaps enough to effectively cause a denial of service? kind regards/ldv p.s.: I refer implicitly to Sam Leffler's comments last year about the likely sources of stuck beacons.
