Is there any software in ubuntu to change network settings easily?

[Jayakandan Velaswamy]

Hi,

I am new to ubuntu and would like to know whether any equivalent
software for ubuntu available to change network settings quickly.

For example, I use my laptop to connect multiple networks, where I
need to have separate network settings and IP configuration for each
network.

for example any software like "IBM access connections" which is
available for windows.
