Wi-Fi
on Raspberry Pi:
A wireless usb adapter is needed for
accessing Wi-Fi on Raspberry Pi.
Step-1
After plugging in the usb adapter to the usb port provided by Raspberry Pi, open the LXTerminal
.
These commands have to be performed in the root mode .To enter the root mode, type the following command:
sudo su
After entering into the root mode type the command:
sudo apt-get update: To get all updates in Raspbian OS
lssub
This will list all the devices connected to the Raspberry Pi .Look for the wlan0 which confirms the reorganisation of the usb adapter by the OS.
Step-2
Install the
wicd-curses, for that type the following command in the LXTERMINAL
sudo apt-get install
wicd-curses
Type the following command:
sudo
wicd-curses
This will show all the networks available in the
surrounding area.
If can’t found any
wireless networks as above then click on the Prefs which is at the bottom of the above window or press P.
Then another window
will open in that find that wireless
interfaces is kept as wlan0, if
not keep manually as wlan0.
Then click OK or press F10, by this it will save the modifications.
Then you will be back
and you will see the window same as above.
Then click Refresh or press R, by this you can see the available wireless networks.
Preferably we have to select the network with 100% signal strength to avoid any errors.
Step-3
After selecting the network “ron”,we have to configure it by clicking on the
Config icon on the window opened.
In this window we have to enter the key
i.e the password of the network “ron”.
Save it by clicking on the F10: OK
option.
Step-4
After configuring the network ,press C
in order to connect to the network.
This will take some
time for obtaining the IP address. When the message is displayed that it is
connected to the network “ron” , exit LXTerminal and open the Epiphany web
browser
If the desires web address is opened
then our objective is completed and usb adapter is successfully configured.
