Equipment needed:

  1. A computer with a network card (NIC)
  2. A DSL Connection
  3. A DSL modem. [Zoom network settings]
  4. A wireless router, this allows your computers to share your DSL connection wirelessly.
  5. Each computer will need a wireless network adapter. This allows your computer to communicate with the wireless router.

Setting up your wireless network

  1. Make sure you have all the equipment listed above.
  2. Make sure you have the documentation for this new equipment nearby for quick access. Since this is only a general guide to setting up a home wireless network, some instructions may vary depending on your hardware.
  3. Make sure all of your equipment (The DSL modem, the router, and all computers) are powered down.
  4. Find a suitable place for your wireless router and DSL modem. If the computers you wish to use are on multiple floors, the router needs to be placed in an area best suited for ALL computers.

    EXAMPLE 1: If you live in a three story house with computers on all three floors, the wireless router should be installed on the 2nd floor.

    EXAMPLE 2: If you have computers at both ends of your house, the best place for the router is in the middle.
  5. Connect the ethernet cable (network cable) to the "Ethernet" port on the modem and the uplink port on the wireless router. (This port could say "Internet" or "WAN", view manual that came with router for more information.)
  6. Power up the wireless router and connect a computer to the router using a physical connection. (Ethernet cable, usb, or serial depending on your wireless router.) Get all settings that your router requires for computers to connect wirelessly. Please review the manual that comes with your wireless router for more information about setting up your router.
  7. Configure all wireless adapters with the settings for the router.
  8. Follow the software setup instructions (if not already completed).
  9. Test the connection by going to Internet Explorer and going to http://www.netdoor.com.
