BW1251 Nov 15, 2006 Chapter 1 – Introduction Thank you for choosing the BROWAN Dual Radio Access Point BW1251. The BROWAN BW1251 operates simultaneously in both 5 GHz and 2.4 GHz frequency bands and is fully compliant to 802.11b/g and 802.11a standard with its high performance and enhanced security. The two Dual-Band radio (a/g + a/g) feature supplies the furthest in flexibility and makes sure low interference and large coverage.
BW1251 Nov 15, 2006 Multiple BSSID Support up to 16 BSSID per radio and each can be configured independently to support different range of security policy, authentication methods, RADIUS servers and VLAN IDs. Each BSSID can be set by its priority on a basis of 802.1p tag or 802.11e EDCA which enables WLAN client device to access wireless link QoS capabilities. Simple Installation Support IEEE 802.3af Power-over-Ethernet as well as external power supply by power adaptor.

Figure 5 – release stand Figure 6 – insert stand Wall Mount BW1251 is also designed for wall mounting. Refer to the step 1 and step 2 to fix the stand on the wall and lock the BW1251 on it.
BW1251 Nov 15, 2006 Connect to the Power Source and Local Network BW1251 can be powered on by connecting to either one of the following two devices: ♦ Power-over-Ethernet ♦ External Power Adapter Case 1 Use the Power-over-Ethernet: Use the enclosed power cord and any IEEE802.3af Compliant POE Power Source Devices to supply power to your BW1251 Access Point. Step 1 Place the Access Point on a flat work surface or mount it on the wall.
BW1251 Nov 15, 2006 The default network settings for your new access point are: LAN port: IP 192.168.2.2 subnet 255.255.255.0 Software Introduction: KickStart The BROWAN KickStart is a software utility included on the Installation CD. The utility automatically detects access points or access controllers installed on your network regardless of its host IP address and lets you configure each unit’s IP settings.
BW1251 Step 3 Nov 15, 2006 After successfully logging on, you will see the main page of the BW1251’s Web user interface: If second method is prefered, please follow the instructions: Step 1 Browan Install the KickStart utility from the product CD. Click Start > Programs > BROWAN > KickStart to launch the application.
BW1251 Step 2 Browan Nov 15, 2006 Select your controller and right click.
BW1251 Step 3 Nov 15, 2006 Enter the BW1251 administrator login credential to access the web management interface. The default administrator log on settings for all access point interfaces are: User name: admin Password: admin01 Step 4 Browan After successfully logging on, you will see the web interface.
BW1251 Nov 15, 2006 Chapter 3 – Application Mode The two Dual-Band radios (a/g + a/g) supply the furthest flexible application. Three application modes are supplied by BW1251: z AP + AP mode z AP + Bridge mode AP + AP Mode AP + AP configuration can be for client density environment. The typical recommended usage is: 11g AP + 11a AP. Figure 9 – AP +AP application mode AP + Bridge Mode AP + Bridge configuration is for environment with last mile issue.
BW1251 Nov 15, 2006 Figure 10 – AP +Bridge application mode Because of the antenna interference, the performance will deteriorate dramatically if the same band (2.4GHz or 5GHz) is used on both RF modules. It is strongly recommended that one RF module uses 2.4GHz and the other uses 5GHz.

Before changing radio settings manually, make sure that your settings comply with the government regulations.
BW1251 Nov 15, 2006 Security Policy Disable C) Regulatory Domain/Channels. Channels – selecting the channel that the access point will use to transmit and receive information. If one channel is defined, it acts as the default channel. Channels list will vary depending on selected regulatory domain and selected band. Multiple frequency channels are used to avoid interference between two radios of this AP, and between nearby access points.
BW1251 Nov 15, 2006 If wireless network environment is stable, which means auto channel selection isn’t needed frequently, set a big value for DCA threshold to gain a stable wireless users’ connection. If wireless network environment changes continually, frequent auto channel selection is needed, set a relatively small value for DCA threshold to let channel change based on wireless environment.
