Changing Network Settings
 

I recently setup a Slackware laptop just to play around with and learn Linux on. My current network setup is basically as follows:

cable modem-->Linksys 4 port wired router-->Cisco 1900 switch-->Slackware Laptop

Now when I first setup this laptop I just set a static IP address and gateway on it. If I wanted to switch back and forth from using DHCP and a static address how would I do that? I can't seem to find any network setting configuration utility within KDE.

Thanks in Advance.
