"Windows is unable to connect to the selected network." The network may no longer be in range. Please refresh the list of available networks and try to connect again." Your in range of the network (right in the same room as the wireless access point). And when you refresh the list, the network still shows up there.

ANSWER:
One possibility is that the wireless network is set to use shared authentication. The Windows XP wireless service assumes that all the WAPs it detects use open authentication. With shared authentication, you have to know the key (password) set by your friend on the WAP. Here's how to configure your computer to connect to a network that uses shared authentication:

Click Start | Connect to | Show All Connections.
Double click the icon for your wireless network adapter.
Click the General tab, then click the Properties button.
Click the Wireless Networks tab.
Click the Add button.
Enter the SSID (network name) that's set in the network's WAP.
Under Network Authentication, select Shared.
Uncheck the checkbox that says "The key is provided for me automatically."
In the Network Key box, type the key set on the WAP, and type it again in the Confirm Network Key box.
Click OK.
This should allow you to connect to your the wireless network.

Disable Wireless Router

You can disable a wireless router SSID broadcast and then connect to the router manually to improve security. This isn’t really necessary if you have WPA-2 enabled and have a secure password, but some people might prefer to have their router in stealth mode. When neighbors or strangers driving around down your street browse for a wireless connection, you might not want anyone to “see” your router. So, disable SSID broadcast and then set up a manual connection in Windows 7.

Disable The SSID Broadcast In The Router

Step one is to log in to the router and turn off the disable SSID broadcast. D-link, Linksys, Netgear and other routers handle this process differently, but you should find the SSID broadcast option in the Wireless settings of the router’s configuration.

Log in to the router and set the SSID broadcast to Disable.

In Windows 7,  go to Start -> Control Panel -> Network and Internet -> Network and Sharing Center. Then click on the “Connect to a network”  option.

Next, click “Manually connect to a wireless network.”

Lastly, fill in the details about your router. While you disabled the broadcast, the router still has its SSID–it just isn’t announcing it to the entire world.  Type the SSID in under “Network name.” Select the security type (WEP, WPA-2, etc) that your router uses. Then put in the password where it says “Security Key.”
You can choose the option to “Start this connection automatically” if you will be using this WiFi connection frequently.
Disable wireless router SSID to improve security, but keep in mind this can make connecting other devices, such as phones, tablets and gaming consoles a nightmare. Some devices may not let you manually input an SSID. If the device does not detect the your router SSID, it simply may not allow you to connect. So, depending on your need for wireless privacy, you may opt to either disable router SSID broadcast or simply give the router a name no one can associate with you and a strong WPA-2 password.
