Configuring Power Management
By default, power management is disabled on the client. To enable power management:
1. Open the RoamAbout Driver Properties window as described in the "Showing Current
Client Settings" section on page 5-21.
2. Click the Power Management tab. Press <F1> on your keyboard for detailed
information about this window.
3. Place a check mark in the Card Power Management check box.
4. Place a check mark in the Receive All Required Multicasts check box
(recommended).
You should keep this option enabled to allow the client to receive multicast messages
from the wireless network. Missing these messages might result in losing the network
connection or other network problems.
5. In nearly all cases, do not change the default value of 100 in the Maximum Sleep
Duration field. However, a value between 100 to 500 milliseconds may be considered
when operating a wireless powered hand-held terminal connected to an infrastructure
network that can handle a less critical latency for optimal performance.
RoamAbout PC Cards with Station Firmware lower than Version 2.00 do NOT support
power management. Enabling power management for such cards can cause unpredictable
computer behavior and a loss of the network connection.
The RoamAbout Access Point automatically supports power management. The only
settable power management parameter is the DTIM period, which should not be changed.
To view or modify the Access Point DTIM period using the AP Manager, select the Access
Point from the Managed List field and click the Wireless Parameters button. In the
Wireless Parameters window, click the Advanced button.
To modify the DTIM period using the console port, choose Module-Specific Options
RoamAbout Access Point Installation Menu, then choose Set Wireless Configuration. If
you do not want to change the value, press <Enter> to go back to the previous menu.
