Incompatibility issues between nl80811 driver and hostapd

Hi,

 

I'm using an Orange PI ZERO HC2 + and usb (mt7601u) wifi dongle to create a hotspot.

The configuration is as follow

 

<HOTSPOT>WLAN0 [  Orange PI ZERO HC2+] WLAN1 <connected to my box>

 

At startup when hostapd is launched to create the hotspot i get the following output . See below <HOSTAPD ERROR>.

 

My hostapd.conf is below.

 

Wlan0 use for xradio_wlan as physical driver

Wlan1 use for mt7601 as physical drive

 

I did some testing. I have the exact same config with a pi3.

And have no problem.

 

I tested the hostapd provided with the orange pi on the pi3, it works no problem.

 

On the orange PI, If i do it the other way round :

wlan1 to deal with hotspot, wlan0 to connect to my box.

 

<HOTSPOT>WLAN1 [  Orange PIZERO ] WLAN0 <connected to my box>

 

I get the same error.

So its does not depend on the underneath driver ( wradio_wlan, or mt7601u).

 

So it looks like something  fishy  with the driver nl80211 declared in the hostapd.conf.

 

Any help would be appreciated.

 

Note: i guess its easy to reproduce, use my hostapd.conf  below: hostapd myhostapd.conf

Hi,

I did some more test using another wifi dongle.

I manage to get the hostapd to work

with a wifi dongle using a rt2800usb driver and disabled the ht_capap in hostapd.conf.

 

Configuration file: nfx-hostapd.conf
Using interface wlan0 with hwaddr 00:25:86:e7:68:35 and ssid "CHEZLAUTRE"
wlan0: interface state UNINITIALIZED->ENABLED
wlan0: AP-ENABLED

 

# Works !

 

So this looks like a dudgy negociation between the nl80811 and undrelying drivers

like xradio_wlan (the onboard wlan interface) or/and mt7601 driver.

 

It's really weird
