Issue
No DNS IP address found
in the DHCP lease or
static configuration.
Steps to Troubleshoot
1. Check the DHCP pool
configuration to see
whether the DNS
server is configured.
2. If you've configured a
static IP address for
the AP, check whether
the DNS server is
configured correctly.
If the DNS server is
not configured
correctly, follow these
steps:
a. Power off the AP
by shutting down
the PoE on the
switch port to
which the AP is
connected.
Alternatively, you
can remove the
physical cable that
provides power to
the AP.
b. Correct the
configuration on
the switch port.
c. Reset the AP to the
factory-default
configuration. See
"Reset an Access
Point to the
Factory-Default
Configuration" on
page
46.
