Intel recommends setting rates 1 and 2 Mbps to Required and 5.5 and 11 Mbps to as shown in the example screen of Figure 1-3. - Page 9 WLAP Manual BSS ID Intel recommends that you set the WLAP Manual BSS ID to its own MAC address. An example is shown in Figure 1-3. This causes the access point to go directly to the Functional state and therefore reduces the time required to begin the wireless connection.

Page 14: Observing The Access Point's Led Indicators
As an access point proceeds through the various states of a wireless AP operation, the LEDs provide certain status indications. The Intel® PRO/Wireless 2011/2011B LAN Product Reference Guides describe how the LED indicators are displayed during the several wireless AP operating states from Initializing through Functional. -

Chapter 4. Using the Link Required Option Chapter 4. Using the Link Required Option As shown in Figure 4-1, Link Required is one of the options for the WLAP Mode entry on the RF Configuration screen. This option allows an access point to create a wireless link in the event it loses its Ethernet connection. - Page 18 Chapter 4. Using the Link Required Option Ethernet Settings on Both Access Points: WLAP Mode = Link Required. WLAP Priority = 8000. WLAP Manual BSS ID = 0. Ethernet Timeout = 0. Ethernet If an access point loses its Ethernet connection, it resets and makes a wireless link to the Ethernet through the other access point.

Designated WLAPs normally adopt the channel number of the root access point instead of using their own channel numbers specified on the System Configuration screen. To view the adopted channel number, refer to the System Summary screen.
