The first one is that the command "iw wlan0 scan" does not scan all frequencies. I've seen a patch submitted to fix an issue in the driver for the 5 GHz band (http://permalink.gmane.org/gmane.linux.kernel.wireless.general/107771) but this is not my issue, because I can not see also several APs in the 2.4GHz band after a scan. The second issue is when I try to associate with an AP using WPA2-PSK with wpa_supplicant (only able to reach this point by setting "scan_freq" in wpa_supplicat.conf file to the frequency used by the AP, because of the inability to perform of a complete scan) I get an error in the driver, as shown in the log bellow: [root ~]$ wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf Successfully initialized wpa_supplicant [ 33.915000] wlcore: firmware booted (Rev 6.3.10.0.133) [ 34.280000] cfg80211: Calling CRDA for country: PT [ 34.290000] cfg80211: Regulatory domain changed to country: PT [ 34.290000] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 34.305000] cfg80211: (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm) [ 34.320000] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (N/A, 2000 mBm) [ 34.320000] cfg80211: (5250000 KHz - 5330000 KHz @ 40000 KHz), (N/A, 2000 mBm) [ 34.330000] cfg80211: (5490000 KHz - 5710000 KHz @ 40000 KHz), (N/A, 2700 mBm) [ 34.340000] cfg80211: (57240000 KHz - 65880000 KHz @ 2160000 KHz), (N/A, 4000 mBm) wlan0: SME: Trying to authenticate with 88:43:e1:57:79:c0 (SSID='[ 34.585000] wlan0: authenticate with 88:43:e1:57:79:c0 A.
