Configuring a Wireless Network
Configuration Tip for Cisco Aironet Access Points
If you are using EAP-FAST, you must increase the EAP request (802.1x) timeout to at least 20 seconds
to ensure that the phone gets the PAC credentials successfully.
To change the request timeout on the controller, follow these steps:
3. Configure Service Set
Identifier (SSID) for each
VLAN
Configure an SSID for a set of wireless devices
to communicate with each other. Several access
points can have the same SSID to support a
group of wireless phones.

6. Configure radio (802.11)
settings
• Data Rate—Set for11 Mbps or to the rate for
the frequency band that you are using.
• Client Transmit Power—After a site survey,

requirements and set a specific Client
Transmit Power setting. The Cisco
Unified
Wireless IP
Phone 7925G uses the same
setting as the access point.
Note If set for Max, the access point does not
advertise Client Transmit Power setting.
