Checking Basic Settings

Mismatched basic settings are the most common causes of lost connectivity with wireless clients. If the
access point does not communicate with client devices, check the following areas.

Default IP Address Behavior

When you connect a 1250 series access point running Cisco IOS Release 12.4(10b)JA or later software
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 IP address, continues to send requests indefinitely.

Enabling the Radio Interfaces

In Cisco IOS Release 12.4(10b)JA or later, the access point radios are disabled by default, and there is
no default SSID. You must create an SSID and enable the radios before the access point will allow
wireless associations from other devices. These changes to the default configuration improve the
security of newly installed access points. Refer to the Cisco IOS Software Configuration Guide for Cisco
Aironet Access Points for instructions on configuring the SSID.
To enable the radio interfaces, follow these instructions:
Step 1 Use your web-browser to access your access point.
Step 2 At the prompt, enter the administrator username and password. The default username is Cisco and the
default password is Cisco. The username and password are case sensitive.
