Solved: Dell laptop won't stay connected to wireless

I need help with my dell inspiron 1011. It's the Nickelodeon edition.

These are screenshots of the connections. I'm sorry, I'm not good at explaining what exactly I mean.
And I messed up, I didn't click, I just hovered over it. Sorry, got my words mixed up.





It's saying it's connected. And I AM for maybe 20 seconds then it stops. I know it's not the router because my friend/neighbor connected to it without a problem and my laptop worked on it perfectly 2 or so months ago. I've checked to make sure everything is up to date on it, and it is. It even says that the wireless card is working properly. We have a Belkin N 150 Wireless Router. But we used wired connections for everything except our laptop and the neighbors(by the way, she only just connected to it last night because we wanted to see if it was indeed the laptop or router and since hers worked, we think it's the laptop.) If you need any more information please let me know because I'm not sure what else to give you.

 

ok. I tried that and it still only kept connection for a few seconds.. Here is the ipconfig info.
