![在没有互联网的情况下为笔记本电脑安装 WLAN 驱动程序](https://linux22.com/image/993812/%E5%9C%A8%E6%B2%A1%E6%9C%89%E4%BA%92%E8%81%94%E7%BD%91%E7%9A%84%E6%83%85%E5%86%B5%E4%B8%8B%E4%B8%BA%E7%AC%94%E8%AE%B0%E6%9C%AC%E7%94%B5%E8%84%91%E5%AE%89%E8%A3%85%20WLAN%20%E9%A9%B1%E5%8A%A8%E7%A8%8B%E5%BA%8F%20.png)
我正在尝试安装 WLAN 驱动程序,以便我的笔记本电脑可以访问互联网。我只能通过 USB 记忆棒将文件添加到这台笔记本电脑,除非我拥有 WLAN 连接,否则没有其他方法可以使用这台笔记本电脑连接到互联网。因此,我无法使用存储库安装任何东西。
WLAN 为:Dell Wireless 1390 WLAN Mini-Card BCM4311 [14e4:4311] 笔记本电脑为:Inspiron 1520 (32 位) Ubuntu 版本为:16.04 LTS
有人能告诉我如何通过 USB 安装驱动程序吗?我尝试过 Broadcom 的建议(http://www.broadcom.com/docs/linux_sta/README_6.30.223.271.txt),但它假定您已经拥有互联网连接。

尝试知识产权命令。
$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether XX:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether XX:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff
如果出现wlan0,则可以继续。
$ ip link set wlan0 up
RTNETLINK answers: Operation not permitted
$ sudo ip link set wlan0 up
