Did I damage the router, or something else?

I'm basically a computer idiot, but you guys have helped me before so I'm going to try here before going any farther.

My Dell PC worked fine yesterday.I have a D-link router that my two daughters use to wirelessly connect their Thinkpads, both worked fine yesterday.

Today I re-arranged my home office. I dropped the router twice while doing it! I reconnected everything exactly as it was. My computer works fine, connects to the internet, but no little wireless icon on the bottom right. My daughters can't connect to the internet. Router lights are lit-up correctly.

??????????
