Important Notes
Change to Default IP Address Behavior
Cisco IOS Releases 12.3(2)JA and later change the default behavior of access points requesting an IP
address from a DHCP server:
address from a DHCP server:
•
When you connect a 1200 or 1230 series access point with a default configuration to your LAN, the
access point requests an IP address from your DHCP server and, if it does not receive an address,
continues to send requests indefinitely.
access point requests an IP address from your DHCP server and, if it does not receive an address,
continues to send requests indefinitely.
•
When you connect an 1100 series access point with a default configuration to your LAN, the 1100
series access point makes several attempts to get an IP address from the DHCP server. If it does not
receive an address, it assigns itself the IP address 10.0.0.1 for 5 minutes. During this 5-minute
window, you can browse to the default IP address and configure a static address. If after 5 minutes
the access point is not reconfigured, it discards the 10.0.0.1 address and reverts to requesting an
address from the DHCP server. If it does not receive an address, it sends requests indefinitely. If you
miss the 5-minute window for browsing to the access point at 10.0.0.1, you can power-cycle the
access point to repeat the process.

Save Interface Level Configuration Before Upgrading to Releases 12.3(8)JEC
If the access points have SSIDs configured at the interface level (rather than at the global level), before
upgrading to Cisco IOS Release 12.3(7)JA and above, upgrade to Cisco IOS Release 12.3(4)JA, save the
configurations, and then upgrade to Release 12.3(8)JEC. This procedure must be followed to make sure
that the SSID configurations are converted from the interface level to global level.

Changes to the Default Configuration—Radios Disabled and No Default SSID
In this release, the radio or radios are disabled by default, and there is no default SSID. You must create
an SSID and enable the radio or radios before the access point allows wireless associations from other
devices. These changes to the default configuration improve the security of newly installed access
points.

Clients Using WPA/WPA2 and Power Save Might Fail to Authenticate
Certain clients using WPA/WPA2 key management and power save might take many attempts to
authenticate or, in some cases, fail to authenticate. Any SSID defined to use authentication
key-management WPA, coupled with clients using power save mode and authenticating using
WPA/WPA2 may experience this problem.

WPA/WPA2 may experience this problem.
A hidden configure level command, dot11 wpa handshake timeout, can be used to increase the timeout
between sending the WPA key packets from the default value (100 ms) to a value between 101 and 2000
ms. The command stores its value in the configuration across device reloads.

Default Username and Password Are Cisco
When you open the access point interface, you must enter a username and password. The default
username for administrator login is Cisco, and the default password is Cisco. Both the username and
password are case sensitive.
