提问by irukeru
On raspberry pi
在树莓派上
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".
I also tried
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.
Should I need to write bash code of my key ?
我是否需要编写密钥的 bash 代码？

From 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.
key/enc[ryption]
用于操作加密或加扰密钥和安全模式。要设置当前加密密钥，只需以十六进制数字形式输入密钥，如 XXXX-XXXX-XXXX-XXXX 或 XXXXXXXX。要设置当前键以外的键，请将 [index] 前置或附加到键本身（这不会更改哪个是活动键）。您还可以使用 s: 前缀将密钥作为 ASCII 字符串输入。目前不支持密码短语。
HBAQXK7W6Yis not a hex key. If this is the ascii key, I think you should enter it as
HBAQXK7W6Y不是十六进制键。如果这是 ascii 键，我认为您应该将其输入为
sudo iwconfig wlan0 key s:HBAQXK7W6Y
But: if this is reallythe key for your for your WLAN, you should change it ASAP. Neverpost a password on a public website.
但是：如果这真的是您的 WLAN 的关键，您应该尽快更改它。切勿在公共网站上发布密码。

There's a similar question at https://superuser.com/q/42460/164903. I think, especially this answer https://superuser.com/a/353818/164903is important. It seems, iwconfigdoesn't support WPA/WPA2, only unencrypted networks or WEP, which is essentially the same nowadays. So you need to use some other approach, like wpa_supplicant.
在https://superuser.com/q/42460/164903 上有一个类似的问题。我认为，尤其是这个答案https://superuser.com/a/353818/164903很重要。看来，iwconfig不支持 WPA/WPA2，只支持未加密的网络或 WEP，现在基本上是一样的。所以你需要使用其他一些方法，比如wpa_supplicant.
