Some Wi-Fi SSID Network names are hidden. To connect to the network you must connect to it manually.
Connecting to a hidden SSID W-Fi Network in Windows 7:
To do this, you need to open the Network and Sharing Center: go to Start Menu -> Control Panel -> Network and Internet -> Network and Sharing Center. In the Network and Sharing Center window you will see lots of shortcuts. Click on the one that says 'Set up a new connection or network'.
The 'Set Up a Connection or Network' wizard will now start. From the list of available options, select 'Manually connect to a wireless network' and click on Next.
Step 3: Complete the Details of the Wireless Network
Now you will have to complete all the fields shown in this window. The first one is called Network name. In it, type the name of the wireless network you want to connect to, which is the equivalent of the Network ID (SSID) field from your router's wireless configuration menus.
The next field that needs to be completed is the Security type used by your wireless network. Depending on the type of security used, make the following selection:
- For WEP security - select WEP.
- For WPA-PSK security - select WPA-Personal.
- For WPA2-PSK(AES) security - select WPA2-Personal.
Also, don't forget to check the other two boxes:'Start this connection automatically' and 'Connect even if the network is not broadcasting'. These two allow you to connect automatically to the hidden wireless network. Once all data is completed, click on Next.
When done, you will see a message which says that you have successfully added the wireless network to your computer. If you are unsure on any of the settings, you can click on 'Change connection settings' and review them all.
This will open a window where you can change all your settings. It can be opened at any time by going toControl Panel -> Network and Internet -> Network and Sharing Center -> Manage Wireless Networks and double clicking on the wireless network.
When done, Windows 7 will automatically connect to the hidden wireless network. Also, the wireless network icon from the taskbar will change to show you are connected to a wireless network.
