Ubuntu Networking :: Netbook Cannot Connect To My Home Wifi Network?

I got my netbook in the mail yesterday, opened it up, logged in, and Windows 7 was installed. Being a Windows hater my whole life, I followed a friend's advice and downloaded Ubuntu netbook, made a USB drive, changed the BIOS settings, all that. Here's when the stupidity occurs--I decided to go ahead and install Ubuntu without trying it, and to delete Windows to do so. A couple minutes later I realized that was a really, really stupid idea, so in a panic I turned my netbook off. I turned it back on and it was still on install but not really moving, so I powered off and on again and went back to the "Try Ubuntu" or "Install Ubuntu" choice screen. I chose "Try Ubuntu" and found that it did not recognize my home wifi network or ask me to join--or any wifi network, for that matter.

Now, it did recognize my wifi network the few minutes I spent on Windows 7, so I tried to change the BIOS settings back to where I could just use that until I figured out the problem. But no matter which setting I tried (HDD/SDD just gives me a black screen, and FDD and LAN do the same as the USB drive), I can't get back to Windows, so I guess I did delete it. Which leaves me with a netbook that can only connect to the internet via ethernet cable. Which kind of defeats the purpose.

Questions I should answer:

1. How am I trying to get online? My home's wireless network. We have a router. All the other laptops in the house connect fine.

2. Who is my internet service provider (and in which country?) COX, United States.

3. Can you get online with any other method? Yes, the internet works fine with an ethernet cable.

4. How am I getting online to post in this forum? My parent's laptop.

5. What hardware are you using? Toshiba N505 netbook and a router. I can give more information about the router if you need it, but I doubt it's the program since the other laptops are fine.

Give me one moment and I will add some code that it gives me when I put in the commands this website tells me to.My two final questions are:

1. Is there any way to recover Windows without buying it again?

2. How can I get Ubuntu to connect to my home wifi network?

EDIT: Here's some code. I have no idea what it means, but hopefully you do.

To run a command as administrator (user "root"), use "sudo <command>".See "man sudo_root" for details.
