On the AP Radio Data Encryption page, enter the same WEP key settings that are
on the root access point.
Also on the AP Radio Data Encryption page, select the same Authentication
Types that are on the root access point.
On the AP Radio Advanced page, enter the root access point's MAC address in
the Specified access point 1 entry field.
On the Express Setup page, select Repeater Access Point as the Role in Radio
Network. The access point reboots when you apply this setting.
The status LED on the root access point should be steady green, indicating that at
least one client device is associated to it. The status LED on the repeater access
point is steady green when it is associated to the root access point and has client
devices associated to it. The repeater's status LED is steady for 7/8 of a second
and off for 1/8 of a second when it is associated to the root access point but has
no client devices associated to it. The repeater access point should also appear as
associated to the root access point in the root access point's Association Table.
Hot Standby mode designates an access point as a backup for another access
point. The standby access point is placed near the access point it monitors,
configured exactly the same as the monitored access point. The standby access
point associates to the monitored access point as a client and queries the
monitored access point regularly through both the Ethernet and the radio. If the
monitored access point fails to respond, the standby access point comes online
and takes the monitored access point's place in the network.
Except for the IP address, the standby access point's settings should be identical
to the settings on the monitored access point. You use the Hot Standby page to set
up the standby access point.
