I am trying to install a WLAN driver in order to get internet access on my laptop. I can only add files to this laptop via a USB stick, there is no other way to connect to the internet using this laptop until I have a WLAN connection. As such, I cannot use repositories to install anything.

WLAN is: Dell Wireless 1390 WLAN Mini-Card BCM4311 [14e4:4311] Laptop is: Inspiron 1520 (32 bit) Ubuntu Version is: 16.04 LTS

Please can someone talk me through how to install the driver via USB. I have tried Broadcom's advice (http://www.broadcom.com/docs/linux_sta/README_6.30.223.271.txt) but it assumes you already have an internet connection.

Try ip command.

$ 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

if wlan0 appear, you can continue.

$ ip link set wlan0 up
