wireless

我刚刚在笔记本电脑上安装了 Ubuntu 12.10。我无法连接到我的D-Link N150 无线路由器当我有 Windows XP 时我就能做到这一点。

问题

每次我登录我的 Ubuntu 时，都会弹出一个窗口，提示：

“无线网络需要身份验证”。

当我输入密码时，无线图标会闪烁一秒钟，然后窗口再次弹出。我谷歌了一下，并按照所有步骤来查找我的操作系统出了什么问题。但我什么也没找到。

请帮我解决这个问题。

我做了什么

我的无线适配器是否被识别？

是的。下面的日志说明了这一点。

sudo lshw -c network
*-network

我的无线设备驱动程序是否安装好了？

我猜司机英特尔 PRO/Wireless 3945ABG [Golan]已预装在此 Ubuntu 版本中。上面的日志driver=iwl3945 driver version=3.5.0-17-generic firmware=15.32.2.9表明驱动程序已安装。但我不确定我的无线适配器 3945ABG 是否支持版本 3.5.0-17。
我尝试了这个命令rfkill list来查看无线是否被阻止？
```
Soft blocked :no
hard blocked  :no
```
在我的网络连接管理器中我有以下设置：
- SSID：********
- 模式：基础设施
- IPv4 设置 - 方法：仅自动 (DHCP) 地址
- IPv6 设置 - 我已将其设置为忽略
- 无线安全：WPA 和 WPA2 个人版。
