Re: Issues with urtwn
Hi,
I do not understand why I have these 'powersave on/off' transitions:
Nov 2 09:01:06 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode
on
Nov 2 09:01:08 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode
off
Nov 2 09:06:08 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode
on
Nov 2 09:06:10 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode
off
Nov 2 09:11:11 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode
on
Nov 2 09:11:12 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode
off
# ifconfig wlan0 -powersave
# ifconfig -v wlan0 | fgrep power
AES-CCM 3:128-bit powersavemode OFF powersavesleep 100 txpower 0
i.e. it seems to be OFF, I even can not set it to on:
# ifconfig wlan0 powersave
ifconfig: SIOCS80211: Operation not supported
What I do can set is the powersavesleep interval to zero:
# ifconfig wlan0 powersavesleep 0
# ifconfig -v wlan0 | fgrep power
AES-CCM 3:128-bit powersavemode OFF powersavesleep 0 txpower 0
But this does not help either.
I fgrep'ed throu the src/sys and it seems that the power save mode
on/off message comes out from
/usr/src/sys/net80211/ieee80211_power.c
/*
* Handle power-save state change in station mode.
*/
void
ieee80211_sta_pwrsave(struct ieee80211vap *vap, int enable)
{
struct ieee80211_node *ni = vap-iv_bss;
if (!((enable != 0) ^ ((ni-ni_flags IEEE80211_NODE_PWR_MGT) != 0)))
return;
IEEE80211_NOTE(vap, IEEE80211_MSG_POWER, ni,
sta power save mode %s, enable ? on : off);
but this does not answer the question why is switching it on/off.
Is it worth to compile a hard change an let return
ieee80211_sta_pwrsave() without doing anything?
Any ideas?
matthias

Re: Issues with urtwn
It's not forcing the adapter itself into ps mode - it's just net80211 doing an off-channel scan thing. Someone has to debug/fix this scan hang thing, I'm out of energy atm :( -adrian On 2 November 2014 07:31, Nathan Whitehorn nwhiteh...@freebsd.org wrote: On 11/02/14 07:29, Matthias Apitz wrote: El día Sunday, November 02, 2014 a las 07:24:02AM -0800, Nathan Whitehorn escribió: Are you running wpa_supplicant?

The issue is that wpa_supplicant is doing scanning in the background, which forces the adapter into power-save mode. -Nathan ___ freebsd-wireless@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to freebsd-wireless-unsubscr...@freebsd.org

I'm willing to dig into this and will start with instrumenting
net80211/ieee80211_scan.c with more debug messages; from there the power
save is activated:
scan_task(void *arg, int pending)
...
if (vap-iv_opmode == IEEE80211_M_STA
vap-iv_state == IEEE80211_S_RUN) {
if ((vap-iv_bss-ni_flags IEEE80211_NODE_PWR_MGT) == 0) {
/* Enable station power save mode */
vap-iv_sta_ps(vap, 1);
Or any other idea? Can you guide me through this?
Thx
matthias
