Answer 1

Directly from their web site:

How do I Enable Encryption or secure my wireless Network?

To enable encryption, you need to log into the router's configuration page: Click on Login -> Advanced Setup -> Wireless -> Encryption

Think up a Hexadecimal code with the appropriate amount of characters for the level of encryption you wish to use (Hexadecimal means you can use any number between 0 and 9, and the letters A through F).

128-bit encryption uses 26 characters. Example:

01 2C 45 67 89 A0 CD EF 01 23 45 6D F9

64-bit encryption uses 10 characters. Example:

01 A3 45 F7 89

I am unsure but am pretty sure you need to contact your internet service provider.

Answer 3

set up your router so that it only uses your MAC (Not Macintosh) address.

To find  your MAC address, ....On your computer, click the Start button and then select RUN.  In the OPEN box type CMS and press Enter.

In the DOS window type IPCONFIG /ALL.  Under the Ethernet adapter look for Physical Address.  It should be 6 pairs of hexdecimal numbers like 0c-00-12-34-56-78.

Now on your router settings, Click on FIREWALL heading and then select MAC filter.  Click Yes on MAC address control.  Add your MAC address to the list.

Now only  your computer can use your router.
