![我的戴尔 Inspiron 15 5570 无法自动连接 Wifi](https://linux22.com/image/1005163/%E6%88%91%E7%9A%84%E6%88%B4%E5%B0%94%20Inspiron%2015%205570%20%E6%97%A0%E6%B3%95%E8%87%AA%E5%8A%A8%E8%BF%9E%E6%8E%A5%20Wifi.png)
我正在使用戴尔 Inspiron 15 5570 笔记本电脑。我有 Windows10 和 ubuntu 14.04LTS(双操作系统)。Wifi 未自动连接,单击 wifi 图标时未列出启用 Wifi 选项。在 Windows 10 中,wifi 会自动连接并正常工作。
如果我连接 wifi 加密狗,可用的 wifi 就会列出,我就可以连接。但如果我移除 wifi 加密狗,列表中不会显示列出的 wifi 名称和启用 wifi 选项。我安装了 broadcam 和 b43 驱动程序。但这没有帮助。
我的命令终端输出。

您需要固件!在网络连接正常的情况下,请打开终端并执行以下操作:
cd /tmp
sudo wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.169.1_all.deb
sudo dpkg -i linux*.deb
重新启动后你的无线网络就能够正常工作了。
