Verify that AirPort or Bluetooth is turned ON, and

• Unable to join networks or pair

devices

 

selected.

 

 

 

• AirPort card not available

2.

(AirPort) Run the Apple System Profiler and verify

Intermittent device or

 

that installed AirPort card supports the channel

 

connection dropouts

 

number used by the wireless access point.

 

 

 

Limited wireless range

3.

(AirPort) Check if the wireless access point

 

 

 

requires special connection and encryption

 

 

 

protocols.

 

 

4.

(AirPort) Check for nearby sources of interference

 

 

 

such as microwave ovens or cordless phones. See

 

 

 

kBase #HT1365: AirPort: Potential source of

 

 

 

interference.

 

 

5.

(AirPort) Check the number of users trying to

 

 

 

use AirPort in the area for possible network

 

 

 

congestion (available bandwidth).

 

 

6.

(Bluetooth) If customer complaints about a

 

 

 

Bluetooth issue with his input device, first use a

 

 

 

known-good Bluetooth input device to perform

 

 

 

tests with computer. Then test customer’s

 

 

 

Bluetooth device on known-good computer to

 

 

 

define which side is creating the communication

 

 

 

issue. See kBase #HT1365: Airport potential

 

 

 

source of interference.

 

 

7.

Isolate potential OS issues by starting up

 

 

 

from original Install media for the computer, a

 

 

 

same-model computer in Target Disk Mode, or

 

 

 

compatible known-good OS on an external drive.

 

 

 

Both AirPort and Bluetooth services are available

 

 

 

when booted from Install disc.
