在树莓上

irukeru@raspberrypi ~ $sudo iwconfig wlan0 mode managed
irukeru@raspberrypi ~ $sudo iwconfig wlan0 channel 11
irukeru@raspberrypi ~ $sudo iwconfig wlan0 essid linksys
irukeru@raspberrypi ~ $sudo iwconfig wlan0 key xxxxxxx
Error for wireless request "Set Encode" (8B2A) :
    invalid argument "xxxxxxx".

我也试过

irukeru@raspberrypi ~ $sudo iwconfig wlan0 key s:xxxxxxx
Error for wireless request "Set Encode" (8B2A) :
    SET failed on device wlan0 ; Invalid argument.

我是否需要编写我的密钥的bash代码？

解决方法

从
man iwconfig

key/enc[ryption]
Used to manipulate encryption or scrambling keys and security mode.
To set the current encryption key,just enter the key in hex digits as XXXX-XXXX-XXXX-XXXX or XXXXXXXX. To set a key other than the current key,prepend or append [index] to the key itself (this won’t change which is the active key). You can also enter the key as an ASCII string by using the s: prefix. Passphrase is currently not supported.

HBAQXK7W6Y不是十六进制键.如果这是ascii键,我想你应该输入它

sudo iwconfig wlan0 key s:HBAQXK7W6Y

但是,如果这真的是您的WLAN的关键,您应该尽快更改.不要在公共网站上张贴密码.

更新：

在https://superuser.com/q/42460/164903有一个类似的问题.我认为,特别是这个答案https://superuser.com/a/353818/164903很重要.看来,iwconfig不支持WPA / WPA2,只有未加密的网络或WEP,这与现在基本相同.所以你需要使用一些其他的方法,比如wpa_supplicant.
