Raspberry Pi is a mini computer with low budget which provides moderate performance rate. There are immense numbers of gadgets which serves the dual function of a controller as well as processor. They endue outrageous amount of efficiency. But we know that greater efficiency will always point towards greater price tag. Hence these highly equipped gadgets provide work at a higher efficiency but they are not at all cost efficient. If you want to setup a device whose performance scale will be low and will support the basic functions. Then always opt for the Raspberry Pi model. It gives you moderate level efficiency but comparatively at a very low price. Raspberry Pi had two models. The model A is not equipped with any internet connection. But the latest model B is pre-equipped with an Ethernet cable wire which provides speed of around 100 Mbps.
However, you can equip both the models with a WiFi connection which will give an ultimate solution to wireless network and increase the efficiency of your machine. There are three different techniques for setting-up of WiFi in your Raspberry Pi. Let us avail the processes behind the techniques and find out which is suitable.
1. USB Dongle
This is the easiest way to acquire WiFi connection in the Raspberry Pi. This method is suitable for both the models and will give undoubtedly high performance. Using a dongle in any kind of system will prove to be cost efficient and tassel free.
Setting up a dongle in a Raspberry Pi will be achieved by following few simple steps. This is done by choosing a Raspbian supported dongle, then plugging it up in the Raspberry pi board and follow few simple configuration steps. After which you will have the WiFi set-up on your RPi board.
Selecting the correct USB dongle or adapter is the primary aim before setting up the connection. The adapter must be a Raspbian supporter. So the Realtek RTL8188CUS chip based adapter is preferred because it supports Raspbian models and for booting it no extra configuration is required. Hence before arriving into a conclusion for buying the right adapter one should have a complete research on it.
The preferred dongle is then plugged in the RPi board and boot-up the board. Now you need to check whether the USB adapter has been identified by the system. It can be check by simply typing the below letters
