Use this file to connect to the network: $ wpa_supplicant -Dwext -i wlan0 -c nf -B Enter the password and press enter, a ‘nf’ file will be created in the same directory with the network name and matching password.
It might look like Ubuntu hangs but it’s waiting for you to type the password for the WiFi network.
Use nmcli dev wifi for a list of available networks if you don’t know the network name. Time to connect to the wireless network, replace the SSID with your wireless network name. We use ‘wlan0’ as a generic device name here but remember to replace it with the logical name found in the previous step. Let’s manually connect to a wireless network but make sure it’s turned on first: $ ifconfig wlan0 up We now have the USB device’s logical name and know how to address it. Notice the WiFi interface is currently disabled. Look for a device with a logical name starting with a 'w' (for wireless) and take note of its name: ‘wlan0’. $ lshw -C networkĬonfiguration: broadcast = yes driver =rt2800usb driverversion =4.4.0-62-generic firmware =0.29 ip =x.x.x.x link = yes multicast = yes wireless =IEEE 802.11abgn Now we need to find the USB device’s logical name, the name we can use to refer to it. Integrated Rate Hubīus 002 Device 001: Linux Foundation 2.0 root hub Run lsusb to list the USB devices the computer knows about: $ lsusbīus 002 Device 003: Fitipower Integrated Technology Incīus 002 Device 002: Intel Corp. Detect the Wireless USB AdapterĬheck if the machine detected the USB adapter first. Useful for computers without a GUI like Ubuntu Server, but this will also work for say, a Raspberry Pi over SSH or any other Linux machine. Let’s configure the wireless adapter via the command-line interface. Great, but how to tell Ubuntu to use the newly installed wireless adapter via the terminal, without a GUI?
I bought a D-Link WiFi USB adapter and plugged it in. The office only has a WiFi network, no Ethernet, and the computer does not have a wireless chip built-in. I installed Ubuntu Server on an older machine at the office.
