无线连接持续禁用或断开连接（Realtek RTL8191SEvB）

我在 Ubuntu 10.10 上有 Realtek RTL8191SEvB 无线网卡：

$ lspci -v | grep Network
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller (rev 10)

当我加载时它的司机据网络经理称有时闪烁着可用网络列表，但它一直处于禁用状态或保持断开连接状态。因此，我无法连接到任何 Wi-Fi 网络（这导致沮丧）。

驱动程序已加载：

$ lsmod

Module                  Size  Used by
r8192se_pci           509932  0

看起来正常：

$ sudo lshw -C network

$ rfkill list all

然而，有些事情发生了：

$ dmesg

那么，有人知道问题可能出在哪里吗？

在 Ubuntu 论坛中，他们建议从 Realtek 下载驱动程序。http://218.210.127.131/search/default.aspx?keyword=rtl8192
