Wifi 在 Linux Mint 上无法工作

我有一台 Dell Latitude E4310 笔记本电脑，过去 4 年一直运行 Ubuntu（有多个版本）。最近我安装了Linux Mint（版本17），然后WiFi无法使用。它在 Ubuntu 下完美运行。

我应该怎么办？是否有我应该安装的驱动程序或软件包？这是输出lspci

此外，运行也service networking restart无法正常工作：

davidlat ~ # service networking restart
stop: Job failed while stopping
start: Job is already running: networking
davidlat ~ #

更新：以下是结果ifconfig -a

davidlat ~ # ifconfig -a

答案1

尝试通过 wpa_supplicant 和 dhclient 手动连接到 wifi。您应该运行以下命令：

wpa_passphrase ssid password > /etc/wpa_supplicant.conf
wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf
dhclient wlan0

ssid=你的wifi名称

执行 wpa_supplicant 后等待它连接，并将其移动到 bg ( ctrl+z; bg ) 或使用另一个终端运行 dhclient。

答案2

通常此类问题反映了没有合适的驱动程序。尝试打开driver-manager并查看是否需要安装一些额外的驱动程序。

如果以上方法不起作用，请使用等synaptic关键字搜索一些无线驱动程序wireless。dell
