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 1240 series access point running
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.
