Help!!! I screwed up my wireless adapter!!!

Help, please! I just came back from vacation and I messed up my HP Pavilion wireless adapter. I did something, which I can't remember, to get my laptop to connect to the hotel wireless. When we got home, it keeps coming up that windows was unable connect to the network. I tried going through to see what I might have changed, but I can't remember. I did a system restore thinking that may fix it, but dice. Is there anyone out there who can tell me how to get my wi-fi connection back? I'm going out of my mind trying to get this straightened out! Windows troubleshooting can't give me an answer either...

-Please disregard this post. Somehow the password on my laptop was deleted and it wasn't connecting to the router. Thanks in advance to anyone who may have been trying to find an answer. Belkin came through and told me how to log into my router then check my laptop. Now I can finally go to sleep!!
