How to simulate network issues on a Android device?

Question

I need to test my app in following scenario:

• connect device to wifi (with the internet).
• simulate internet interruption (lack of the internet but the device must stay connected to the wifi network).
• after few seconds the internet need to be active again.

I could simulate this pulling the adsl cable out of my ruter, but then it won't reconnect fast enough. Is this any way to simulate this programmatically?

If you have a Mac, you can do it with Network Link Conditionner. It's really efficient, see here the step to install it :
