That is wierd I have never had to configure my network I just plug my cable in and it is connected.

You shouldn't need to install applications from source 99% of the time on ubuntu. You use adept package manager and install them that way.

Does your lan have DHCP or must you configure static IP address? Post the configuration settings you are using.

I have static ip address. I am sending my netwrok settings with an image that i have saved while using xp. btw i have configured ip address etc from manage network connections.but can't give the full netmask.I t is only asking for netmask prefix. as i have said i am using kubuntu 9.04.(I have just removed the last three digits for security,dnt mind).

Wierd!!!!!!!!!!!may be ur connection is different from me.bt i m using lan with static ip address.If it will be done by so simple method i would be here with any other problem.

If you just need a static ip address, I would ditch the default network manager and set it up through /etc/network/interfaces

Open the file to edit

Code:

gksudo gedit /etc/network/interfaces

When you open it you should see something like

Code:

# The loopback interface
auto lo
iface lo inet loopback

and probably nothing else.

To that you'll add the other settings (but leave that bit alone)

Code:

# The loopback interface
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian installation
# (network, broadcast and gateway are optional)
auto eth0

iface eth0 inet static
       address 192.168.1.101

       gateway 192.168.1.1

       netmask 255.255.255.0
       network 192.168.1.0
       broadcast 192.168.1.255

Replacing the address, gateway, netmast, and so on with your settings.

There is a lot more you can add if needed.

NetworkManager won't work right once you edit that file. I'm a little reluctant to suggest just removing it altogether.

You can

Code:

sudo aptitude purge network-manager network-manager-gnome

I'm not sure what the best way to simply disable it is. The Ubuntu wiki suggests

Code:

sudo /etc/dbus-1/event.d/26NetworkManagerDispatcher stop
sudo /etc/dbus-1/event.d/25NetworkManager stop

Then create two files with just the word exit in them.

Code:

echo "exit" | sudo tee /etc/default/NetworkManager
echo "exit" | sudo tee /etc/default/NetworkManagerDispatcher

After either do

Code:

sudo /etc/init.d/networking restart

And you should be good.

I just noticed you were using Kubuntu not Ubuntu.

In my previous post replace gksudo gedit with kdesu kwrite.

Or you can use a command line text editor and do

Code:

sudo nano /etc/network/interfaces

the package manager requires an internet connection to work or to be configured to use a CDROM to install software
