Acer Aspire One 532h-2676 上的 AR9285 Wireless（又一个）

Question

人们在 askubuntu.org 上询问有关此无线设备的问题实际上有数百个。我花了大约 12 个小时试图让它工作，但无济于事。是时候寻求一些专家的帮助了。

信息：

• 宏碁 Aspire One 532h-2676
• AR9285 无线
• Ubuntu 12.04 / 通过以太网连接更新（抛弃 Windows - 所以这需要工作！）

问题：

无线设备连接到路由器并接收内部 IP，但是，除了暂时的 Internet 访问之外，似乎没有任何麻烦似乎能够为我提供任何东西。我可以使用ping -c 10 192.168.0.XX我的地址，但无法 ping 路由器 (192.168.0.1) 或互联网 (google.ca/com)。

我在 askubuntu/linuxforums/ubuntuforums 上的其他地方尝试和阅读的内容

• 已安装sudo apt-get install linux-backports-net-${uname -r)（预期的兼容性驱动程序）
• 编辑../ath9k.conf用options ath9k nohcrypt=1（读一篇关于硬件加密的问题）
• 尝试使用wicd（阅读帖子，这适用于 12.04 之前的某些版本）
• 完全删除并重新安装 NM sudo apt-get purge network-manager*... sudo apt-get install network-manager*（阅读这对某些人有用的帖子）

人们通常会询问其他问题的详细信息

启动时的 dmesg

Answer 1

我在这里遇到了同样的问题，并将其追溯到两个硬件rfkill交换机中的冲突。

在syslog我注意到以下细节：

NetworkManager[668]: <info> found WiFi radio killswitch rfkill0 (at /sys/devices/pci0000:00/0000:00:1c.1/0000:02:00.0/ieee80211/phy0/rfkill0) (driver (unknown))
NetworkManager[668]: <info> found WiFi radio killswitch rfkill1 (at /sys/devices/platform/acer-wmi/rfkill/rfkill1) (driver acer-wmi)

我似乎已经通过acer-wmi以这种方式列入黑名单解决了它：

echo blacklist acer-wmi | sudo tee /etc/modprobe.d/blacklist-acer-wmi

然后您可以重新启动或输入sudo rmmod acer-wmi。
