Configuring Wifi and Internet in Ubuntu.
I have been personally dealing with this problem from past 1 week. But didn’t get the time to solve this because of busy schedule. Some days back I installed Ubuntu on my machine and started playing with its features. Accidentally I somehow removed the Network Manager of Ubuntu, which is the default Gnome Network App in Ubuntu. At this time I didn’t knew how to solve this problem as my internet is not working now.
I tried searching from other machine but wasn’t able to get an effective solution. I tried many commands and tutorials but all in vain. These are some of the commands I tried.
- sudo /etc/init.d/networking restart – To restart network Daemons in Ubuntu and configuring the Interfaces
- sudo ifdown eth0 – To stop eth0 interface
- sudo ifdown wlan0 - To stop wireless Lan Interface
- sudo ifup eth0 – To start eth0 interface
- sudo ifup wlan0 – To start wlan0 interface
- ifconfig – To check all the network configurations
- sudo gedit /etc/network/interfaces – To edit the interface file in which all these interfaces are stored and configured
Originally your interface file looks like this:
auto lo
iface lo inet loopback
But the most good solutions that I found was downloading and installing WICD which is a third party free Network Management client for Linux Distributions. I downloaded the latest package from http://wicd.sourceforge.net/download.php for Ubuntu.
Wicd is an open source wired and wireless network manager for Linux which aims to provide a simple interface to connect to networks with a wide variety of settings.
Wicd is easy to use just install and configure it for your router settings and you are good to go. It is also good because you can make a connection default in this i.e. whenever a connection breaks in between it can go back to same connection, whereas in Network Manager this isn’t possible. The above commands are very useful for manual configurations especially 1,6 and 7.
If Wicd doesn’t gets activated try running the command sudo /etc/init.d/dbus restart or restart your machine for the setting to take effect.
