无线网卡不能上电

[linux5588]

无线网卡灯不亮。怎么也启动不了无线，iwconfig可以看到wlan0 其中有一项power magentment off 。试了N个方法还是不亮。回去我把无线网卡的型号贴上来，看看各位有方法吗。。。

如果不行。请教下怎么安装无线网卡的驱动。没有驱动精灵一样的工具吗

[vickycq]

1. 报告机器厂商型号
2. 终端运行把结果全部复制贴上来

代码： 全选

sudo apt-get install lshw rfkill
sudo rfkill list all
sudo lshw -C network
lspci -knn
sudo iwconfig
sudo ifconfig -a
cat /etc/network/interfaces
cat /etc/issue
uname -a

==========================================

iwconfig可以看到wlan0 其中有一项power magentment off

那是电源管理关闭，不是电源关闭

无线网卡灯不亮，怎么也动不了无线

能启动无线但灯不亮也是可能的。

如果你的机器是这一款，不知你有无试过 acer/asus 无线硬阻塞通病处理方法
创建 /etc/modprobe.d/blacklist-acer_wmi.conf 加入 blacklist acer_wmi

代码： 全选

echo 'blacklist acer_wmi' | sudo tee /etc/modprobe.d/blacklist-acer_wmi.conf
sudo update-initramfs -u -k all
sudo reboot

你用的 LiveCD / LiveUSB 系统？

[vickycq]

你用的 LiveCD / LiveUSB 系统？

嗯，是的。我试试网络能正常用不。好多个版本多不行。深度linux倒是可以使用。
我装下系统试试。live-cd重启就熄火了

此法对 LiveCD 无效，装好系统后再试

[poloshiao]

无线网卡灯不亮

先把燈 亮不亮 放一邊
先看看 能否上網
確定可以上網了
再來探討 燈 亮不亮

live-usb下面不能使用无线
重新安装了优麒麟15.5到硬盘后无线没有问题。

现在我的win7分区启动不了。怎么修复引导呀。win7在C盘没有动过，引导记录覆盖了。

是 Legacy BIOS + MBR分割区？UEFI + GPT分割区？
在 Linux 下运行一次

代码： 全选

sudo apt-get install os-prober
sudo update-grub

看 os-prober 组件能否探测到 Windows?

如果不能，Linux 下运行

代码： 全选

sudo fdisk -l

应该正常了，重启选择 Windows 7 试试。

Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.

你的 GRUB_TIMEOUT 之前可能是 0，导致你开机看不到 GRUB 菜单。
现在根据提示，可能被自动设置为非零了。重启应该看到 GRUB 菜单。

[linux5588]

启动成功了。非常感谢

看来 Ubuntukylin 15.04 LiveCD 安装 GRUB 到硬盘时没有 os-prober？
