How to Set Up WiFi on the Raspberry Pi
But lets face it, your Raspberry Pi project is not always going to be deployed close to a network outlet — so what do we do?
Setting up a Raspberry Pi using the Raspbian OS to access your wireless network is easy — this guide will guide you through the process. As you may have experienced with other types of hardware devices not all devices are plug-n-play. Sometimes you will need to download a driver to make them work. I very recommend you do the same — it could save you a lot of headaches. Power up the Raspberry Pi — remember at this point the WiFi adapter does not work yet.
You are still going to need some other means of being able to control the Raspberry Pi either via a keyboard or remotely using a wired network connection. After booting and logging-in you want to make sure that the Raspberry Pi found your new wireless adapter. To look at which peripherals the operating system found when booting run the following command: dmesg more You can use the spacebar to scroll down a page at a time — towards the end you will see something similar to the following lines: [ 3.
All that is left is to configure your WiFi connection. After opening the file in nano you will see a screen like this: To configure you wireless network you want to modify the file such that it looks like the following: auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wpa-ssid "Your Network SSID" wpa-psk "Your Password" You will need to put your own SSID and password into the appropriate places.
If nano asks if you want to Save modified buffer? At this point everything is configured — all we need to do is reload the network interfaces. This can be done by running the following command warning: if you are connected using a remote connection it will disconnect now : sudo service networking reload After reloading the network interface and re-connecting to the pi if you are using a remote connection — you can now check the status of our WiFi connection by running: ifconfig The result should look something like this: wlan0 Link encap:Ethernet HWaddr faa inet addr
How to setup WiFi on Raspberry Pi 3?
WiFi and Bluetooth adapters. This type of setup is needed only if you setup Raspberry Pi in Headless Mode i. We have already seen a tutorial on how to setup Raspberry Pi 3 without monitor and keyboard earlier. It is very important that you complete that setup first to proceed with WiFi setup. Setup until this step is enough for setting up the WiFi.
Now, we need to connect our Raspberry Pi to this network. In this file, we need to add the name of the WiFi network and also the password. So, in order to open the file, type the following command and hit enter. Just below the existing content, enter the following command. In our case, it is SLNP. Type the password in the psk section. Then it will ask you whether to save the changes or not. Type y to save and hit enter. Now, we need to turn on the WiFi Adapter.
For that, type the following commands one after the other. It automatically gets connected to the WiFi Network. In our case, the new IP Address is Now we can login using the username and password.
To check the connection, type the following command in the Putty terminal. This will return the details of the connection like IP Address, transmitted and received bytes etc. Click on the double arrow symbol once again to see the list of WiFi networks available near the Raspberry Pi. Select the WiFi network from the list. In our case, we have around 9 networks and our network is SLNP.
You will now be asked to enter the Pre Shared Key of the network. This is nothing but the password of the WiFi connection. Enter the password and click on OK.
You can see that the Raspberry Pi is connected to WiFi network of choice and is highlighted with a green check mark. Related Posts:.

How To: WiFi on your Raspberry PI
Connecting with an ethernet cableis great if you want to leave it connected to your router with a physical cable. Be careful when choosing a WiFi adapter for the Raspberry Pi though, because not all of them will work out of the box. I found that this one on Amazon works great without any driver installations needed.
Still, there are a couple things that need to be set up for any WiFi adapter to work properly with your Raspberry Pi. If the internet is not working, try resetting the WiFi router or the modem to resolve the issue. In case the issue persists, the problem is most likely with your Raspberry Pi.
