Hi,
I have 2 iMX6 devices running uBlox Lily WiFi, mrvl firmware
sd8801_uapsta.bin in kernel 4.19.75. In my office, a WiFi router is
just 1 meter away, the WiFi signal should not be a problem. One device
could connect to the WiFi router well and stably, one could not, here
were error messages:

Both devices were installed the same firmware and software, if it was
firmware / software issues, both would not be able to connect to WiFi,
as one device could connect to the office WiFi router well, it could
not the WiFi router problem either.
If I move the faulty one to my home, it could connect to my home WiFi,
so the device does not have WiFi problem, that is really confusing,
what could cause that kind problem and how to debug and fix it?
Thank you.

Hi,
there are WiFi routers like AVM which are implement the WiFi Stack in a
stricter way than other routers or other WiFi chips-firmware.
I mention this cause weh ad some issue with a cypress wifi firmware which leads
to "sometimes" disconnect from routers. And we figured out that this was mostly
the case with AVM. We are in contact with AVM in it turns out that the AVM
router work proberly. The issues was with the cypress chipset firmware. Now we
are in contact with cypress and they accepted the issue.
So it is not always a connman problem :-) .
Best regards
Jan

I started IWD with
sudo /usr/lib/iwd/iwd -d
it then 'magically' (without connman) connected to the wifi - I assume it
reads connman's settings for that. IWD found all five wifis:
src/station.c:station_add_seen_bss() Processing BSS '04:d9:f5:26:4f:69'
with SSID: rivendell, freq: 5825, rank: 5932, strength: -6400
src/station.c:station_add_seen_bss() Processing BSS 'fa:1a:67:32:fa:1f'
with SSID: rivendell, freq: 2417, rank: 4707, strength: -3900
src/station.c:station_add_seen_bss() Processing BSS 'fa:1a:67:32:fa:20'

with SSID: rivendell, freq: 2427, rank: 4306, strength: -5500
src/station.c:station_add_seen_bss() Processing BSS '04:d9:f5:26:4f:65'
with SSID: rivendell, freq: 5240, rank: 2999, strength: -7000
src/station.c:station_autoconnect_next() Considering autoconnecting to BSS
'04:d9:f5:26:4f:69' with SSID: rivendell, freq: 5825, rank: 5932, strength:
-6400
5500 and 2417 should be the repeater, to which I was closer at the moment.
But it decided to connect to the router's high 5Ghz network.
And then started connmand:
sudo connmand -n -d plugins/iwd.c --wifi=3Diwd_agent
** (connmand:1923): WARNING **: 17:38:47.484: error
fi.w1.wpa_supplicant1.UnknownError
It didn't print any frequency information.
IWD seems to occasionally roam between the wifis :) For a brief period it
picked 2417. Overall it highly prefers 5825 even if that is the farthest
one away (to be fair, it worked - I didn't encounter connection issues).
Thanks,
Torsten

That really worries me, my WiFi router is TP-Link AC1200 dual band
router, it should have no problem for my device to connect it as I
mentioned I have two devices one could connected without any issues.
that definitely won't be my WiFi chip uBlox Lily issues, if it was,
the another unit would not be possible to connect to my WiFi router in
office.
I am not saying it is connman problem or mwifiex problem or kernel
problem, what I like is to get helps and clues from open source
communities to help me to debug and to find issues, it could be my
contributions as well if there could be potential open source bugs to
be found from my test, debug and report :-).
Thank you.
