我有一台 HP Pavilion Slimline s3100n，无论如何我都无法连接 wifi，也无法在任何情况下使用网络管理器或 wicd 保持连接...我为此抓狂不已，根本无法解决问题...切换到 wicd 不起作用，在连接编辑器中输入密码也不起作用...什么都不起作用...其他人对我说的都是中文，我真的只想让我的电脑正常工作...请帮帮我...我会提供任何需要的信息来帮助我。只要教我如何找到这些信息就行。请不要不帮我就跳过这个问题...我太沮丧了...

答案1
您的无线设备使用驱动程序 rt73usb。某些驱动程序在混合模式 WPA 和 WPA2 网络上存在问题。请尝试将您的路由器设置为仅 WPA2。某些驱动程序在 80211N 上存在问题；请尝试将您的路由器设置为 B 和 G 速度，但不要设置为 N。最后，您可以执行以下操作：
gksudo gedit /etc/modprobe.d/rt73usb.conf
添加一行：
options rt73usb nohwcrypt=Y
校对、保存并关闭 gedit。重新启动并向我们提供您的报告。编辑：gedit 为 gksudo，而不是 sudo。
