Re: bgscan

J'ai jeté un oeil sur la doc officiel, et j'ai trouvé ça qui, si j'ai au moins compris partiellement ça pourras peux être, t'aider, ou pas :

AP scanning/selection

By default, wpa_supplicant requests driver to perform AP scanning and then

uses the scan results to select a suitable AP. Another alternative is to

allow the driver to take care of AP scanning and selection and use

wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association

information from the driver.

1: wpa_supplicant initiates scanning and AP selection; if no APs matching to

the currently enabled networks are found, a new network (IBSS or AP mode

operation) may be initialized (if configured) (default)

0: This mode must only be used when using wired Ethernet drivers

(including MACsec).

2: like 0, but associate with APs using security policy and SSID (but not

BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to

enable operation with hidden SSIDs and optimized roaming; in this mode,

the network blocks in the configuration file are tried one by one until

the driver reports successful association; each network block should have

explicit security policy (i.e., only one option in the lists) for

key_mgmt, pairwise, group, proto variables

Note: ap_scan=0/2 should not be used with the nl80211 driver interface (the

current Linux interface). ap_scan=1 is the only option working with nl80211.

For finding networks using hidden SSID, scan_ssid=1 in the network block can

be used with nl80211.

When using IBSS or AP mode, ap_scan=2 mode can force the new network to be

created immediately regardless of scan results. ap_scan=1 mode will first try

to scan for existing networks and only if no matches with the enabled

networks are found, a new IBSS or AP mode network is created. ap_scan=1

Moi, j'essayerais de mettre l'AP scannig sur 2.
Après j'avoue que j'en pas plus que toi.
