Install zero config network manager in Dapper..

First of all it would be a good idea to delete the old network manager icon from the top Gnome bar, by right clicking it & selecting remove from panel.

Open a terminal & type in the following line..

sudo apt-get install network-manager-gnome

Next you need to open the run programme application by pressing Alt+F2 & typeing in the supplied box.. nm-applet.

This will install the new network manager programme & start up the included task bar utility.

Unfortunately this won’t work as yet, because of the old network manager that’s still being used from the default installation. You need to disable the old manager by following these steps..

Navigate the top Gnome menu & locate the System/Administration/networking option to bring up the old network manager.

Click on the top connection to highlight it, then click on properties.

Untick the enable this box & then press the ok button to close the window & get back to the main programme screen.

Do exactly the same for all wired/wireless connections within the old network manager, before pressing the ok button at the bottom of the program to save your new settings & exiting.

Open up a termnal & type sudo gedit /etc/network/interfaces

Delete all lines except..

auto lo
iface lo inet loopback

Then save the file & exit gedit.

 

Now would be a good time to restart your computer. Some people just log out & then log straight back in but I prefer to fully shut down, just to make sure that all goes well.

Once your computer has rebooted.. make sure that the new network manager is fully enabled by right clicking the icon on the top Gnome bar & ticking enable networking & enable wireless.

You should now have any local wireless networks showing up whenever you left click the network manager icon. Just Remember to make sure that the hardware switch on the front of the laptop (that controls your wireless device) is turned on 😉

This is only a basic guide to installing the new NetworkManager. It will allow you to connect to networks which have the ability to assign an i.p address by DHCP. Check out the Ubuntu forum for advice & tutorials on assigning static i.p addresses & encryption.

 

p.s If you get the error.. “The NetworkManager applet could not find some required resources. It cannot continue.”

Open up a terminal & type in .. sudo gtk-update-icon-cache -f /usr/share/icons/hicolor/

I’ve only come across this error once, & this fixed it straight up 😀
