我的戴尔 Inspiron 15 5570 无法自动连接 Wifi

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。

~$ lspci -nnk | grep 0280 -A3

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。
