Get wireless working under Ubuntu Server 16.04

[pwwalker]

This worked for me to configure WiFi in my Ubuntu 16.04 LTS server:

1. Install wpasupplicant if not already installed:

sudo apt install wpasupplicant

2. Find out your Wireless interface name using "iwconfig" command.
If it is not installed, install it using

sudo apt install wireless-tools

The interface name will be like wlp3s0 or wlp3s0b1 or something similar to this.

3. Add the Wireless interface configuration to /etc/network/interfaces.
For example, taking wlp3s0b1 as Wireless interface name:

auto wlp3s0b1
iface wlp3s0b1 inet dhcp
        wpa-ssid <YOUR WIFI NETWORK NAME>
        wpa-psk <YOUR WIFI NETWORK PASSWORD>

4. Save /etc/network/interfaces and run

sudo service networking restart

.

I've configured my files in the same way but hangs when I try to restart the service. I just can't seem to get an IP.

Restarting networking is deprecated; i.e. no longer useful. The correct method is:

sudo ifdown wlp3s0 && sudo ifup -v wlp3s0

Of course, substitute your interface name you found with:

ifconfig

I wouldn't use DHCP if I wanted to easily ssh and ftp into my server, but, hey, that's just me. I usually take the fast, easy, fool-proof way if I can.
