Chapter 1 Introduction Thank you for purchasing Micronet Wireless LAN Bridge SP912. It operates seamlessly in the 2.4 GHz frequency spectrum supporting the 802.11b (2.4GHz, 11Mbps) wireless standards. It's the best way to add wireless stable to your existing wired network. SP912 has high transmitted output power and high receivable sensitivity. High output power and high sensitivity can extend range and coverage to reduce the roaming between APs to get more stability wireless connection.
1.2 Package Contents Open the package carefully, and make sure that none of the items listed below are missing.

Wireless extensions to Ethernet networks Network managers in dynamic environments can minimize the overhead caused by moves, extensions to networks, and other changes with wireless LANs. Wired LAN backup Network managers implement wireless LANs to provide backup for mission-critical applications running on wired networks. Training/Educational facilities Training sites at corporations and students at universities use wireless connectivity to ease access to information, information exchanges, and learning.
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 if 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.

Chapter 4 Switch Between Access Point & Bridge This chapter describes the steps to switch from Access Point to Bridge, and Bridge to Access Point. This device can be configured as an Access Point or a Bridge. By default, this device is configured as an Access Point, and the default IP address is 192.168.1.1. 4.1 Access Point to Bridge Step1: Enter the default IP address of the Access Point into the address bar of the web-browser (192.168.1.1).
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. 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.
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. You may change the user name and password after you login. In order to do so, refer to section 5.5 Admin.
5.2 System The System page is the first page that is displayed after logging in. This page displays information about the Access Point. You may refresh this page by clicking on the System link on the left-hand side of the page (image left). Described below is the information listed along with an image. AP firmware: displays the version of the firmware installed on the Access Point. WLAN Primary firmware: displays the primary firmware of the wireless LAN card inside the Access Point.
5.3 Wireless Click on the Wireless link on the navigation bar in order to configure the wireless settings of Access Point.
