Enabling a wireless device

Tails 啟動後， Wi-Fi、 WWAN 與 WiMAX 設備也會跟著啟動。

But all other kinds of wireless devices such as Bluetooth, GPS and FM devices are disabled by default. If you want to use such a device, you need to enable it first.

Enable a wireless device

這個技巧是使用命令列指令。

1. Tails 啟動時， 設定一個管理員密碼.

2. Choose Apps ▸ System Tools ▸ Console.

3. Execute the following command to open a root console.

   sudo -i

4. To find out the index of the wireless device that you want to enable, execute the following command:

   rfkill list

   指令可能會傳回以下的結果：

   0: phy0: Wireless LAN
           Soft blocked: no
           Hard blocked: no
   1: hci0: Bluetooth
           Soft blocked: yes
           Hard blocked: no
   2: gps0: GPS
           Soft blocked: yes
           Hard blocked: no
   

   設備代號是出現在描述每個設備 開頭前三行的數字。本例中，藍牙設備的 編號是 1，而 GPS 設備的編號是 2。當然每個人 的情況可能稍有不同。

5. To enable the wireless device, execute the following command. Replace index with the index found at step 2:

   rfkill unblock index

   以下是一些指令執行的例案，每個人的情況 或有不同差異：

   rfkill unblock 2

6. To verify that the wireless device is enabled, execute the following command again:

   rfkill list

   這個結果應該和步驟 2 之一有點類似，但 在步驟 3 啟動的設備應該 不會再遭軟封鎖。

   指令可能會傳回以下的結果：

   0: phy0: Wireless LAN
           Soft blocked: no
           Hard blocked: no
   1: hci0: Bluetooth
           Soft blocked: yes
           Hard blocked: no
   2: gps0: GPS
           Soft blocked: no
           Hard blocked: no
