How to Create a Wireless Access Point Using a WiFi Adapter & Cable Modem

by Matthew Schieltz

Anyone can create a wireless access point to receive an Internet signal if it's not possible to have a physical connection between a computer workstation and a cable modem. In fact, wireless access points are used both in household networks and in businesses such as hotels where access to Wi-Fi networks exist for guests and patrons. To set up your wireless access point, the Wi-Fi adapter and cable modem are necessary, but you'll also need a wireless router.


Connect the cable modem to the cable and an electrical outlet. Watch for the green lights that should appear on your cable modem; refer to the instruction manual of your particular cable modem to determine which lights should come on.


Hook up an Ethernet or Category-5 (Cat5) cable from the Internet port on the cable modem to the Internet port on the wireless router. Plug the wireless router into an the electrical outlet; watch for the green lights that indicate that the router is receiving a Wi-Fi signal from the modem and that a wireless access point has been created.


Connect your Wi-Fi USB adapter or card to your laptop computer or desktop if it does not contain an internal wireless card. This adapter makes it possible for your computer to propagate the wireless 802.11 b/g/n signal. Once connected, the Wi-Fi adapter should instantly be recognized by your computer if the adapter is a plug-and-play device and search for the wireless access point you created with your router and modem. Follow any other instructions for the Wi-Fi adapter model if any are required (e.g. inserting a CD or installing adapter drivers).


Secure your wireless access point by first pointing your Internet browser to the wireless router's configuration page. Most wireless routers have a settings page that can be found by typing in an address such as "" into your Internet browser's address bar. Create a unique SSID (secure set identifier) and encryption key password for your wireless access point to ensure only authorized individuals have access to your wireless network. Select the option in your router's configuration page to disallow the SSID broadcast, which prevents network outsiders from seeing that you have a private network.
