Ieee Power Management (Dtim Period); Secure Access - Cabletron Systems RoamAbout User Manual

IEEE Power Management (DTIM Period)

Power Management can extend battery life of clients by allowing the client to sleep for
short periods of time while the AP buffers messages for the client.
You may need to balance wireless performance versus battery-life. Power
Management can impose a more active use of the wireless medium, which might lead
to more frequent transmission delays, experienced as slower network response times
during file transfers.
With slower response times, the client may spend more time in operational mode
resulting in less effective power management. In such cases, disabling power
management on the client might result in better throughput performance.
RoamAbout PC Cards with Station Firmware lower than V2.00, do NOT support
Power Management. Enabling Power Management for such cards can cause
unpredictable computer behavior and a loss of the network connection. To check the
Station Firmware version, run the RoamAbout Client Utility, choose Diagnose Card
then choose the tab Version Info. If the secondary firmware version is less than V2.0,
check the RoamAbout web site for available upgrades.
The AP supports IEEE Power Management. The DTIM (Delivery Traffic Indication
Message) interval value sets the buffering time. For example, the default value of 1
corresponds to 100ms of sleep time. It is highly recommended that you do not change
this value.

Secure Access

When Secure Access is enabled, the AP denies access to wireless clients that do not
use the correct Wireless Network Name. When Secure Access is disabled, the AP
allows access to wireless clients that use ANY (all uppercase) as the Wireless Network
Name or have a blank Wireless Network Name.
