askubuntu.org 上有数百人询问有关此无线设备的问题。我花了大约 12 个小时尝试让它工作,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(放弃 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,无论我怎么花招,似乎都无法为我提供任何东西,除了暂时的互联网访问。我可以访问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 上尝试过和读过的内容
- 已安装
sudo apt-get install linux-backports-net-${uname -r)
(预期兼容驱动程序) - 编辑(阅读有关硬件加密问题的帖子
../ath9k.conf
)options ath9k nohcrypt=1
- 尝试使用
wicd
(阅读帖子,这对 12.04 之前的版本有效) - 完全移除并重新安装 NM
sudo apt-get purge network-manager*
...sudo apt-get install network-manager*
(阅读帖子,这对某些人有用)
人们通常会询问其他问题的详细信息

解决它。
答案1
我在这里遇到了同样的问题,并将其追溯到两个硬件交换机的冲突rfkill
。
我syslog
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
这种方式列入黑名单解决了这个问题:
echo blacklist acer-wmi | sudo tee /etc/modprobe.d/blacklist-acer-wmi
然后您可以重新启动或者输入sudo rmmod acer-wmi
。
答案2
没想到,还有另外一个线程。
我从另一个帖子粘贴了我的答案。askubuntu 是否提供了合并帖子的方法?
以下是对我有帮助的内容。它并不完美,但有效。
按照此威胁中的说明进行操作http://ubuntuforums.org/showthread.php?t=1286503&page=5
重新启动时,wifi 无法使用。现在,您要做的就是暂停笔记本电脑并恢复。令人惊讶的是,恢复时网络是通的。我一直在使用这个,现在我可以应付,因为暂停-恢复周期只需要大约一分钟。
我的设备是带有 AR9285 的华硕 u32u,升级到 13.04 后就出现了问题
