Changing Access Point
Properties
The Access Point Properties page displays the properties of the selected access
point. You can change properties by entering values in the fields and clicking the
radio buttons described below. When you are finished, click Save.
■
Device Name —This name appears on the device manager window.
■
Device Location —Optionally, you can enter the location of the access point.
■
Wireless LAN Service Area —To enable clients to roam among multiple
access points, the access points must have identical WLAN service areas. To
maintain wireless association, the WLAN service area on the client and the
access point with which it is associated must match exactly. If you are
associated with the access point that you are configuring and you change the
access point WLAN service area, make sure to change the client WLAN service
area also.
Setting Network
Properties
The Network Properties page lets you change the settings shown below.
■
Network Setting —This setting lets you change the IP address of the access
point.
To let the access point get an IP address automatically from a DHCP server, click
Obtain an IP address automatically and click Save .
To specify an IP address, click Specify an IP address , enter the IP address
parameters in the spaces provided, and click Save .
If you change the IP address, you cannot continue to configure the access point
using the old IP address. If you want to continue configuring this access point,
you must close your browser and start a new configuration session.
When you specify an IP address, the access point cannot act as a DHCP server.
Make sure that clients are using IP addresses on the same network.
■
Wireless DHCP Server —If your wired network has a DHCP server, it is
recommended that you use it. However, the access point provides a DHCP
server that can automatically assign addresses to clients in a simple, all-wireless
network.
The access point’s default IP address is 169.254.xxx.1, where xxx is the last byte
of the access point’s MAC address. When it is acting as a DHCP server, the
access point can assign up to 253 IP addresses to currently associated wireless
clients. The IP addresses range from 169.254.xxx.2 to 169.254.xxx.254.
If the access point detects that another DHCP server is available, all wireless
clients get IP addresses from that DHCP server.
If your wired LAN DHCP server goes down, the access point assigns IP
addresses after the lease periods on the previous IP addresses expire.
To let the access point act as a DHCP server when there is no other DHCP server
available, click
Enable and click Save .
System Status The System Status pages show currently associated clients, general
information about the access point, and details about wireless
configuration settings.
