- The radio is malfunctioning.
- Too many wireless clients are connected to the AP.
- There are some non-802.11 devices around that interfere with the WLAN signal.
- Wireless clients are transmitting a large amount of media data through the AP.
Explanation: On the Access Point View screen, a technician can check the operating status of connected APs. One important indicator is the noise level on a channel. Noise is usually considered to be the energy received from non-802.11 sources. Ideally, the noise level should be as low as possible, usually around −90 or −100 dBm, so that 802.11 signals can be received intelligibly and accurately.
