The best way to secure your wireless router is to establish a security key using the setup option of the router. Usually that is accessed by logging into the router as the admin user. Once its set up you will need the key to connect to the router.

1. Log into your Wireless Router or Access Point.
Open your web browser and type in the IP address of the Wireless
Router or Access Point. (The Router’s default is 192.168.2.1, the
Access Point’s default is 192.168.2.254.) Log into your Router by
clicking on the “Login” button in the top, right-hand corner of the
screen. You will be asked to enter your password. If you never set
a password, leave the password field blank and click “Submit”.
Click the “Wireless” tab on the left of your screen. Select
the “Encryption” or “Security” tab to get to the security
settings page.
2. Select “128-bit WEP” from the drop-down menu.
3. After selecting your WEP encryption mode, you can type in
your hex WEP key manually, or you can type in a passphrase
in the “Passphrase” field and click “Generate” to create a WEP
key from the passphrase. Click “Apply Changes” to finish. You
must now set all of your clients to match these settings. A hex
(hexadecimal) key is a combination of numbers and letters from
A—F and 0—9. For 128-bit WEP, you need to enter 26 hex keys.
For example:
C3 03 0F AF 4B B2 C3 D4 4B C3 D4 E7 E4 = 128-bit key
4. Click “Apply Changes” to finish. Encryption in the Wireless
Router is now set. Each of your computers on your wireless
network will now need to be configured with the same
security settings.

For the computer/laptop to connect to the wireless router, the wireless card in the computer/laptop needs to be configured with the netgear's wireless settings eg. SSID and encryption etc.
