Possible Cause of Failure

Devices Can't Connect using Wi-Fi

• Complete the Setup Wizard. The Wi-Fi radio on the device is turned off

by default, and the Setup Wizard activates it. For users who do not wish

to use the Setup Wizard, log into the device using a Cat5e Ethernet

cable, and activate the Wi-Fi radio manually. See the Administration

Guide for details on activating the Wi-Fi radio.

No Power

• Power up the switch and your computer if they are turned off.

• If your access point is using PoE, make sure your PoE switch is powered

on and the lights indicate that you have a link. See

Hardware Installation" on page

• Verify that the power button is on; only applicable if you are not using

PoE.

• Verify that the devices on your network are not plugged into a

switchable outlet.

Bad Ethernet Connection

• Check the state of the indicator lights. See

Installation" on page

• Check the Ethernet cable to ensure that it is firmly connected to your

devices. Devices connected by the Ethernet cable can include the WAP

device, any switches, and your computer.

• Verify the connected switch has auto-negotiation enabled. The access

point and the switch need the same negotiation parameters set.

Bad Image

After a new firmware installation, if the Power light is flashing quickly,

contact system support; see

Incorrect IP Address

The most likely cause of connectivity failure is an incorrect IP address. The

Web browser may be pointed to the wrong IP address, or your computer

may be configured with an IP address that is not in the same subnet as the

device.
