Deep Dive
1. Check for nearby interference sources in the
2.4/5GHz range such as microwave ovens or
cordless phones (Knowledge Base HT1365)
2. (AirPort) Check the number of users trying to
use AirPort in the area for possible network
congestion. Move closer to base station to
improve signal reception.
3. (Bluetooth) Move devices closer together.
4. Check wireless performance with a known-good
system/device.
5. (AirPort) Wireless base station checks:
a. Base station is not set to low-power
transmission mode.
b. Base station is not set to a slower protocol
mode (802.11b).
c. Check for possible Wi-Fi channel overlap
(nearby base stations using adjacent channel).
6. Isolate OS by booting from original install
media (10.6.x). Attempt to connect to base
station (AirPort) or pair with wireless keyboard
(Bluetooth)
7. Use Software Update to make sure all AirPort and
Bluetooth software and firmware updates have
been applied.
