>Synopsis: wifi does not resume when waking up from zzz
>Category: wifI
>Environment:
        System      : OpenBSD 6.2
        Details     : OpenBSD 6.2-current (GENERIC.MP) #398: Thu Feb  1 18:22:03 MST 2018
                         [hidden email]:/usr/src/sys/arch/amd64/compile/GENERIC.MP

        Architecture: OpenBSD.amd64
        Machine     : amd64
>Description:
        I put the computer to sleep using zzz. When I resume, the internet does not connect automatically like it used to. I have to manually ifconfig to get the wifi connected again. I just updated OpenBSD today so I think it's related to the update. Before the update, wifi always reconnected automatically when I resumed from zzz.
>How-To-Repeat:
        Put computer to sleep using zzz. Resume/wake up computer later.
>Fix:
        Manually connect using ifconfig

iwn auto-connects fine for me after resume from sleep with this kernel:

$ sysctl kern.version
kern.version=OpenBSD 6.2-current (GENERIC.MP) #399: Fri Feb  2 18:28:58 MST 2018

I am using this iwn device:

iwn0 at pci3 dev 0 function 0 "Intel Centrino Advanced-N 6200" rev 0x35: msi, MIMO 2T2R, MoW, address xx:xx:xx:xx:xx:xx

If your problem persists, can you please show the full additional
dmesg output generated by: ifconfig iwn0 debug

On my Lenovo X230 Tablet, a momentary zzz causes the same result, but only on
5GHz net. This happens on 6.2 amd64 snapshot from 2018-02-05 (yesterday).

Steps to reproduce and results are below [1], where iwn0 only works on 5GHz
after boot, or after return from zzz, if it's first brought up on 2.4GHz net.

My device:

| iwn0 at pci2 dev 0 function 0 "Intel Centrino Ultimate-N 6300" rev 0x3e: \
| msi, MIMO 3T3R, MoW, address 3c:a9:f4:82:f4:a4

fw_update tells me I have "iwn-firmware-5.11p1: ok". The /etc/firmware/iwn*
files are dated Jan 21 16:44 (-0700).

Full dmesg below, with iwn0 in debug mode.


Richard

=======
[1]
I initially noticed problems after I upgraded from 6.2 stable to the 6.2
2018-02-01 and 2018-02-05 snapshots. My trunk0 interface stopped being able to
use iwn0 on the 5GHz SSID for failover at boot time.
However, using the 2.4GHz SSID for failover works.
I can get 5GHz SSID working by first bringing iwn0 up on the 2.4GHz SSID, then
changing to the 5GHz SSID. One way: edit hostname.iwn0 and `doas sh
/etc/netstart iwn0`.
A zzz then sticks iwn0 in a non-responsive state.
If I then `ifconfig iwn0 down delete`, and switch back to the 2.4GHz SSID
(edit hostname.iwn0, redo netstart), I again get a working iwn0 on the 2.4GHz net.
 From there, I can switch back to the 5GHz SSID as above, until reboot or zzz
requires a repeat.

There is a known behaviour of the firmware where, on a 5 GHz channel,
it will not transmit a probe request unless it first sees some other
valid packet on the channel. This has to do with how the firmware deals
with regulatory domains, which restrict 5Ghz channels in some parts of
the world. I don't really understand exactly how it works, and how we
can control it. But there are some parameters which go into the scan
command which you could try tweaking to see if they have any effect,
and let us know your results.

If you want to try playing with these parameters to the firmware,
(i.e. change them, recompile kernel, and test) you can find them
in if_iwnreg.h:

/*
 * For active scan, listen ACTIVE_DWELL_TIME (msec) on each channel after
 * sending probe req.  This should be set long enough to hear probe responses
 * from more than one AP.
 */
#define IWN_ACTIVE_DWELL_TIME_2GHZ (30) /* all times in msec */
#define IWN_ACTIVE_DWELL_TIME_5GHZ (20)
#define IWN_ACTIVE_DWELL_FACTOR_2GHZ (3)
#define IWN_ACTIVE_DWELL_FACTOR_5GHZ (2)

/*
 * For passive scan, listen PASSIVE_DWELL_TIME (msec) on each channel.
 * Must be set longer than active dwell time.
 * For the most reliable scan, set > AP beacon interval (typically 100msec).
 */
#define IWN_PASSIVE_DWELL_TIME_2GHZ (20) /* all times in msec */
#define IWN_PASSIVE_DWELL_TIME_5GHZ (10)
#define IWN_PASSIVE_DWELL_BASE (100)
#define IWN_CHANNEL_TUNE_TIME (5)

The firmware command is built in at iwn_scan() in if_iwn.c, so see
there for more details.

An 'active scan' happens if you have an SSID configured with 'ifconfig iwn0
nwid foo', and 'passive scan' happens if no SSID is configured.

My theory is that because of the firmware's behaviour described above,
sometimes 5Ghz APs do not show up in the list, as you can see in debug
output I'm quoting below.

This time it was not found, even though other 5GHz APs are in the list.
So the firmware didn't pass your AP's beacon/probe response to the driver,
probably because it never received it.

Confirmed that this was the source of the behavior I was seeing.

Other devices were sending valid packets in my prior testing where the 5GHz
SSID was seen reliably.

I moved to the 6.2 snapshots at the same time as other devices stopped being
present.

Bringing the other devices back on line returns the 6.2 snapshots to almost
always working on 5GHz.

Thank you. I will try adjusting the active dwell times when I next have a
quiet 5GHz SSID.
