This question already has an answer here:
I am trying to block a specific Wireless Network such as "Router_Home" because everytime I wake up my laptop the first thing that the Network Manager does is to try connecting to this Network.
Can you show me how to do that using the terminal or/and GUI ?
EDIT: I know I can uncheck the "connect automatically" option. But I want to know how to block a wireless network totally.
I am using Ubuntu 12.10
