I am checking something out in my connection and I just wanted to ask, is there a way to auto-disconnect and connect from the internet.

For example say I want to disconnect now and reconnect to the internet in 0.05 seconds, is there any program that does that on Fedora Linux?

You just have to script the following commands

sudo ifconfig eth0 down
sudo ifconfig eth0 up

With eth0 being the interface used (it can be wlan0 or anything else). – Pikrass Jan 19 '10 at 18:08
You should be able to save a few keystrokes by doing sudo ifdown eth0 and sudo ifup eth0. – VxJasonxV Sep 27 '10 at 12:28
