今天去实验室，按你说的用传统配置文件试了下，没法获得
ip地址,

qide@inspiron:~$ sudo ifup wlan0
wpa_supplicant: WARNING: plaintext or ascii WPA key has 5 characters,
wpa_supplicant: it must have between 8 and 63 to be valid.
wpa_supplicant: If the WPA key is a 256-bit hexadecimal key, it must have
wpa_supplicant: exactly 64 characters.

用 sudo iwlist wlan0 scan 获得ap的信息如下：
