無法在 Debian Wheezy 上使用 TP_LINK / TL-WN823N / Realtek 8192cu usb 無線適配器

我的桌面有一個 TP-LINK TL-WN823N 無線 USB 棒（Realtek 模組 8192cu）。我無法讓網路管理員使用它。

Wicd說沒有找到無線網路，標準網路監視器說無線已斷開連接。我已經執行了https://wiki.debian.org/rtl819x。在底部我有/etc/apt/sources.list文件的內容並執行apt-get update。（在執行這些測試時，電腦通過乙太網電纜連接）

從看iwconfig

lo        no wireless extensions.

wlan1     IEEE 802.11bgn  ESSID:off/any

     Retry  long limit:7   RTS thr=2347 B   Fragment thr:off
     Encryption key:off
     Power Management:off

eth0      no wireless extensions.

ifconfig wlan1:

ifup wlan1:

Ignoring unknown interface wlan1=wlan1.

作業系統版本的輸出lsb_release -a：

No LSB modules are available.
Distributor ID: Debian

輸出apt-cache search Realtek：

從做，apt-get install firmware-realtek：

嘗試通過以下方式啟動 wlan0 ifconfig wlan0 up：

wlan0: ERROR while getting interface flags: No such device

但ifconfig wlan1 up工作原理是沒有出現錯誤

編輯配置文件以wicd將其定向到wlan1，因為它正在註冊但未看到。

sudo nano /etc/wicd/manager-settings.conf 

並設置而不是wlan0或none

wireless_interface = wlan1
