Dear All,
I'm testing the current OpenWrt (master/HEAD) on RT5350F
Olinuxino. Unfortunately the WiFi interface doesn't seem to
work properly in client mode. `iwinfo wlan0 scan` runs
successfully and shows my AP, but when i configure the
interface as client and try to connect, the authentication
seems to be successful (according to dmesg), but the wlan0
interface never gets IP address, even if i explicitly call
udhcpc. If i set a static IP address for wlan0, and ping my AP,
i have around 88% packet loss. There is no any relevant message
in dmesg which could give a hint about the reason.
As a counter-check, i flashed the an old OpenWrt image from the
HW vendor with kernel 3.18, and with that one the WiFi
interface works properly.
Does anyone else experience similar issues (either on this or
any other RT5350F board)? Do you have any advice what to look
into to sort this out?
Thanks,
Hi,
When you build master, did it already contain commit "hostapd:
update to git HEAD of 2018-05-21, allow build against wolfssl" ?
Could you also try to build the 18.06 which does not contain
this one and compare?
You never know..
No, it didn't have that commit yet. Now i build an image with
this new hostapd version and I'll report. Thanks for the hint!
It's the same behavior with the newer hostapd version as well. It
seems I'll have to look into how to debug WiFi performance issues...
Hi Zoltan,
When the issue appears, could you run following commands please and
share the output?
My untrained eyes didn't spot anything unusual, but here are the
outputs:
- iw phy0 info
https://pastebin.com/2hQ5wbng
- iw wlan0 info
https://pastebin.com/NPZZ1dBL
- iwinfo
https://pastebin.com/RHuJuYYu
- dmesg (just to be sure)
https://pastebin.com/1kTUY9t4
Thanks for the dumps.
Well, thanks for looking into this!
I see you are connected using channel 13 and HT40, but channel 12 and
channel 14 next to it are marked as "No IR"
Could you try 1 more thing please?
Please put the AP manually on channel 1 and retry.
Just tried it, no change...
In the meantime i also tried with an other AP, without security
enabled, but got the same behavior.
Thanks,
Koen
Thanks,

I'm trying to look into this from a different angle: the vendor also
provided an updated version of the control registers (stored in mtd2 on
the flash)[1]. Although i have this updated version on my HW, i
contacted also the Olimex support for advice.
