28 CHAPTER 4: SETTING THE WIRELESS CLIENT CONFIGURATION
Manually set the power management
When this radio button is selected, you can select the power mode manually. You
may want to select this mode, for example, if your computer cannot detect its
power source or if you want to improve performance by forcing continuous access
even though you are using battery power.
Network Traffic Accelerator
If only 3Com 11 Mbps Wireless LAN equipment is being used, it is recommended
that you turn this option on to increase the rate at which traffic is handled.
Automatically release/renew the IP address
Your Internet Protocol address (IP address) contains the information that allows
network traffic to find its way to your computer.
This option requires a Dynamic Host Control Protocol (DHCP) server. The client’s
network configuration must be set to obtain its IP address automatically. For more
information on DHCP, see the documentation for your operating system.
When this box is checked, your computer automatically requests another
IP address if you travel outside of your subnet, so the network connection remains
active. Leave the box unchecked if your network does not have a DHCP server.
To force the system to release and renew an IP address, click Release/Renew Now.
You may want to click this button, for example, if you cannot establish association
with the network or if you roam in an installation that has multiple access points
and you lose network association.
Changing Your
Password
The Change Password utility lets you update the password used in the access
control list of the access point with which the client is associated. This is only
applicable if you have configured the client to use 128-bit Dynamic Security Link
security.
Because access points maintain separate User Control Lists, you must update the
password separately on each access point that you associate with.

cannot detect its power source.
