Can't connect to wireless

Hello everybody.

I just got an HP Touchsmart IQ524. I installed Windows 7 32 bit, and now I can't connect to my wireless.
To make everything worse, a friend let me try his wi-fi adapter, and with it everything works fine.

I went to HP.com, and there's no driver for the wireless, just a Realtek update, which I ran. Before running it, I got the message "the passphrase is incorrect", after running it, now it just tells me it can't connect, without even asking for the password.

I also tried (as suggested in another thread), resetting winsock, with no results.

Can anybody please help me?

Thanks in advance.

What does Device Manager show for Network Adapters? Any yellow marks?

Try Updating Drivers and Software with Windows Update

Since the computer is new (still under warranty), it would be a good idea to contact HP, see what they have to say.

Sorry, I should've been more specific.

I bought the computer used, so no warranty.

All the drivers in the device manager show to be working properly. I did update the network driver, and it didn't make any difference.

Nobody?

Thanks for the replies. I finally figured it out. Just so happens the ADAPTER was malfunctioning (that computer has a USB adapter built in, that you can unplug if needed). I got another one from the guy that sold it to me, and now everything works fine.
