1. Cards that form a wireless network whenever they are within range of one another In ad hoc mode each client is peer to peer would only have access to the resources of the other client and does not require an access point This is the easiest and least expensive way for the SOHO to set up a wireless network The image below depicts a network in ad hoc mode Wireless LAN Client Wireless LAN Client B Infrastructure Mode The infrastructure mode requires the use of an access point AP In this mode all wireless communication between two computers has to be via the AP It doesn t matter 1f the AP is stand alone or wired to an Ethernet network If used in stand alone the AP can extend the range of independent wireless LANs by acting as a repeater which effectively doubles the distance between wireless stations The image below depicts a network in infrastructure mode Wireless LAN Client Wireless LAN Client Access Point Wireless LAN Client Chapter 2 Hardware 2 1 Hardware Configuration E RJ 45 Ethernet Connector Provides 10 Mbps connectivity to a wired Ethernet LAN E Reset Button By holding this down for more than five seconds the unit will reset to its factory default settings E Power Supply Connector Connects to the power adapter 2 2 Hardware Installation A Configure your notebook or PC with a wireless LAN card B For a wired LAN connect your PC s Ethernet port to the unit s LAN2. ask you to confirm your decision Click on the OK button You will then see the following screen as the Access Point restarts into Bridge mode 4 2 Bridge to Access Point Step1 Enter the default IP address of the Bridge into the address bar of the web browser 192 168 1 1 Leave the user name and password fields blank and click on the OK button Step2 After you have logged into the Bridge click on the Admin link on the navigation bar You will then see the following screen Commands Resetto factory defaults Switch to AP Step3 Click on the Switch button to switch the device from Bridge to Access Point mode Step4 The Bridge will then ask to you confirm your decision Click on the OK button You will then see the following screen as the Bridge restarts into Access Point mode Chapter 5 Access Point Web Configuration 5 1 Logging In To configure the Access Point through the web browser enter the IP address of the Access Point into the address bar of the web browser default IP 192 168 1 1 and press Enter You will then see the login window Leave the User name and the Password field blank and then click on the OK button Connect to 192 168 1 1 802 11b Access Point User name Us Password C Remember my password i Cancel You may change the user name and password after you login In order to do so refer to section 5 5 Admin After you login you will see
