internet?!

On the 24th, 2 days ago, there was a power outage in my suburb from like 5-9ish so that was a dark boring ass night. When the power came back, the internet wasn't working, so the router was reseted and reconfigured but my laptop still wouldn't connect. Everybody else in the house could, I don't know why I can't. I tried plugging the router and modem directly into the laptop and still wouldn't. I don't understand why it doesn't work. Atm its tuesday and I am at uni and the UNIWIDE is working for me so.. I don't get it... why internet at home isn't working for me.
