Let me know if AC> things are better, worse or the same. r250675, my ususal test (300 mbit AP -> Client). Looks good. First of all, it gives me stable 100-150Mbit, so it could negotiate HT rates again without TCP :)
And it sustain for 600 seconds in this mode, which was impossible before. There was several such messages: May 16 12:57:31 gateway kernel: ath0: ath_tx_tid_bar_suspend: tid=0xffffff8000d82230, bar_wait=0, bar_tx=0, called May 16 12:57:31 gateway kernel: ath0: ath_tx_tid_bar_tx_ready: c4:85:08:3f:9e:c2: tid=0xffffff8000d82230 (0), bar ready May 16 12:57:31 gateway kernel: ath0: ath_tx_tid_bar_tx: c4:85:08:3f:9e:c2: tid=0xffffff8000d82230, called May 16 12:57:31 gateway kernel: ath0: ath_tx_tid_bar_tx: c4:85:08:3f:9e:c2: tid=0xffffff8000d82230, new BAW left edge=676 May 16 12:57:31 gateway kernel: ath0: ath_bar_response: c4:85:08:3f:9e:c2: called; tap=0xffffff8000d7f3a0, atid=0xffffff8000d82230, txa_tid=0, atid->tid=0, status=0, attempts=1 May 16 12:57:31 gateway kernel: ath0: ath_tx_tid_bar_unsuspend: c4:85:08:3f:9e:c2: tid=0xffffff8000d82230, called But no full stalls.

At second test, after ~300 seconds of test in battery mode it drops to non-N speeds and never recovered. -- // Black Lion AKA Lev Serebryakov <[email protected]> _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "[email protected]"
