I've fixed debugging AC> to be a little clearer (to me, at least.) Bad news: at this series of tests I didn't get N rates at all, and got station deassociation again. Twice. It seems, that it depends on HT/aggregation negotiation. Log attached. Log contains two series of tests: (1) Only debug was set to 0x9<zeroes>20 value (see "sysctl" call) Result: non-N rates, deassociation, automatic re-association in 30 seconds without my intervention. (2) Additional "wlandebug +crypto +assoc +state" was called. Result: the same. You could see "borders" of tests by "sudo" calls. Notebook was on AC power. --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org> ------------0F01F014F338C6184 Content-Type: application/octet-stream; name="messages-r250706-tdma.log.xz"
