You have set in /etc/wpa_supplicant.conf mode=1 (image in post #1), wpa_supplicant.conf(5) states:

mode    IEEE 802.11 operation mode; either    0 (infrastructure, default) or
         1 (IBSS).    Note that IBSS (adhoc) mode can    only be    used with
         key_mgmt set to NONE (plaintext and static    WEP), or key_mgmt set
         to    WPA-NONE (fixed    group key TKIP/CCMP).  In addition, ap_scan
         has to be set to 2    for IBSS.  WPA-NONE requires proto set to WPA,
         key_mgmt set to WPA-NONE, pairwise    set to NONE, group set to ei-
         ther CCMP or TKIP (but not    both), and psk must also be set.

Try without setting mode, or if necessary set as advised in the man page.

I change WiFi chip device to Atheros AR9170 to resolved.
