Help please!! Problem with linksys

I have a linksys wireless network setup and it has been running fine. Today, on one of my computers, I intentionally disabled internet on that computer only in order to do some offline things by right-clicking on the wireless icon on the bottom right then clicking disable.

Now, it wont let me reconnect with my network, I right click -> Start, but this linksys window comes up saying "No Assosiation with Access Point"

What should I do?
