我无法使用 HP Pavilion dv6-7080-se 上的硬件开关 -f12- 启用无线功能。
启用无线选项是灰色的,所以我无法启用它。
启动 ubuntu 时我按下 f12 - 启动 wifi 驱动器 - 登录一段时间后 wifi 就可以正常工作了。
我的系统的结果iwconfig
如下
eth0 no wireless extensions.
eth1 IEEE 802.11abg ESSID:off/any
Mode:Managed Access Point: Not-Associated
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:on
lo no wireless extensions.
我的系统的结果rfkill list all
如下 1
: hp-wifi: Wireless LAN
Soft blocked: no
Hard blocked: yes
2: hp-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: yes
3: hp-bluetooth: Bluetooth

这是我的sudo lshw -C network
结果。

在附加驱动程序应用程序中,检查任何与 STA 相关的驱动程序并禁用它们。
打开终端并输入以下命令:
sudo apt-get remove b43-fwcutter broadcom-sta-common broadcom-sta-source firmware-b43-installer firmware-b43-lpphy-installer firmware-b43legacy-installer bcmwl-kernel-source
现在,输入以下命令:
echo "blacklist bcma" | sudo tee -a /etc/modprobe.d/blacklist.conf
echo "blacklist brcm80211" | sudo tee -a /etc/modprobe.d/blacklist.conf
重新启动 Ubuntu。
再次打开终端并输入以下命令:
sudo apt-get install bcmwl-kernel-source broadcom-sta-common broadcom-sta-source firmware-b43-installer
包安装完成后,重新启动。
打开附加驱动程序。
启用 Broadcom STA 驱动程序。
您的 Wifi 现在应该已处于活动状态并且可以正常运行。
答案2
尝试
sudo rfkill unblock all
然后
sudo ifconfig eth1 up
它应该会打开你的 wifi。
答案3
HP Pavilion dv5 和 Mint 16 Petra 也存在同样的问题。对我有用的方法是将 BIOS 重置为出厂默认设置。似乎没有其他方法可以在 BIOS 中访问 wifi,并且触摸 wifi 天线使其在启动时变为蓝色状态不起作用,尽管这在 Windows 上是可行的。
