Enter the encryption key. Once you have enabled security on your wireless adapter, you need to enter the unique security key for your gateway. To do this, set the network encryption type to hexadecimal, and enter your 10-digit wireless encryption key found on the bottom of your gateway.
IMPORTANT NOTE TO MAC OS X USERS: You must enter the "$" character at the beginning of the 10- digit wireless encryption key. For example, if the wireless encryption key is 1234567890, enter "$1234567890". Doing so indicates to the OS that the key is in hexadecimal format.
In general, accept your adapter's defaults. The default value for the remainder of configurable settings for your network adapter should allow your wireless adapter to communicate with the gateway. Although the gateway is set by default to communicate using channel 6, it is not required to change your adapter to this setting as most adapters will automatically detect the appropriate channel.
