Hello,

 

We got some problems with connman and wpa_supplicant with a WLC and static IP.

 

The BSS is a WPA2 PEAP-MSCHAPV2 with RADIUS.

We are using connman 1.26 and wpa_supplicant 2.23. 

 

The authentication and association is ok but we receive a deauth from the AP 
after about 2 minutes. That’s  also ok, the WLC sent it because we have not 
informed the WLC about our IP (the BSS does not uses DHCP).

However, no that point, if we use only wpa_supplicant, it reassociates 
automatically without problems:

 

wpa_supplicant.conf :

 

ctrl_interface=/var/run/wpa_supplicant 

update_config=1

 

 

Here is a log of iw event –f on that case.

 

wlan0 (phy #0): disconnected (by AP) reason: 1: Unspecified

wlan0 (phy #0): scan started

wlan0 (phy #0): scan finished: 2462, ""

wlan0 (phy #0): auth 08:d0:9f:ec:47:c0 -> 00:08:ee:08:5f:96 status: 0:

wlan0 (phy #0): connected to 08:d0:9f:ec:47:c0

 

So, when we start any communication the orphan packet will transmit the ip to 
the WLC and we’ll be inside the BSS without problems.

 

But, and here comes the problem, if we use connman, we are not able to 
reassociate. The auth/assoc triggered by a connect in connmanctl goes ok, but 
when the deauth is received and the scan triggered wpa_supplicant continuosly 
reports the BSS as “skip-disabled” and no authentication/association is done by 
the supplicant (unfortunately I don’t have the logs now, but I’ll post them as 
soon as I get access to them)

 

So, why it does not reconnects ? What are those “skip-disabled” which don’t 
show up without connman ?

 

I don’t know if it is related some way, but the SSID created on the settings 
file is a number, different from the Name I specified on the wifi_XXX.config.

 

Thanks for reading J
