我使用 TP-Link (TL-WN723N,版本:2.2) USB 适配器在 Windows 7 上连接到 wifi 互联网。它的网络是 WEP 加密类型,使用安全密钥我可以连接到互联网。但在 Ubuntu 12.10 中,我可以在网络管理器中看到 wifi 网络可用,但每次我尝试连接它时,它都会一遍又一遍地询问安全密钥。我使用了正确的安全密钥,但它无法连接到网络!
我是否必须在 Ubuntu 中为其安装正确的驱动程序?如果需要,该怎么做?
这有点令人困惑,因为系统显示有可用的无线网络,并将网络配置为 WEP 类型,因此适配器似乎正在工作。但它无法连接到互联网。

从以下网址下载适用于 Linux 的 RTL8188CUSRealtek.com
右键单击并选择“在此处提取”,提取下载的档案。
将原始模块列入黑名单:
echo 'blacklist rtl8192cu' | sudo tee -a /etc/modprobe.d/blacklist.conf
...然后重新启动。
构建新模块:
cd RTL8188C_8192C_USB_linux_v3.4.4_4749.20121105
sudo bash ./install.sh
它将需要一分钟才能完成,并且应该立即开始工作。
PS:保留下载的文件,因为每次内核更新后都需要重做最后一步。
