If your Raspberry Pi is already turned on, turn it off and connect the USB WiFi Dongle to any of the USB ports on the Raspberry Pi. The following steps are common whether your Raspberry Pi is connected to a Monitor and Keyboard or it is accessed using a remote SSH Client like Putty in a headless fashion. We will now see how to configure the Raspberry Pi 2 to access a WiFi network.
This particular adapter supports IEEE 802.11b/g/n protocols with speeds up to 150Mbps. The WiFi Dongle used in this project is a Tenda W311MI USB Adapter. In order to connect a Raspberry Pi 2 or older devices (which doesn’t have on – board WiFi Adapter), we need to use an USB type WiFi Dongle. We have also seen how to enable and configure the WiFi in Raspberry Pi 3. We have already seen how to setup a Raspberry Pi Computer in headless fashion i.e. In this tutorial, I’ll show you how to setup WiFi on Raspberry Pi 2 using a WiFi Dongle and get connected to a WiFi network. In previous tutorial, I’ve explained how to connect Raspberry Pi 3 to a WiFi Network using the on – board WiFi Adapter. Hence, in order to access WiFi using Raspberry Pi 2, we need to use an external adapter like a WiFi Dongle. Setting up WiFi on Raspberry Pi 2 is different from setting up on Raspberry Pi 3 as Raspberry Pi 2 or earlier models doesn’t have on board WiFi Adapter like Raspberry Pi 3 does.
