Deploying and Troubleshooting the Wireless Network
This section provides the following information to help you understand, deploy, and
troubleshoot your wireless environments:

Understanding Received Signal Strength
Received signal strength (RSSI) is measured from connected wireless client devices to
the wireless cable modem. This value can significantly impact wireless
speeds/performance. It is determined by:
Materials (for example, open air, concrete, trees)
Distance between wireless clients and the wireless cable modem
Wireless capabilities of the client devices
To determine the received signal strength, refer to
Using the Wireless Access Control
Option on page 52
and review the
RSSI
value. A signal strength of -30dBm to -67dBm is
considered optimal. Levels of -67dBm and lower (for example, -70, -80, etc.) have a
downward impact on wireless data throughput.
