Deploying and Troubleshooting the Wireless Network
This section provides the following information to help you understand, deploy, and
troubleshoot your wireless environments.
Topics
See the following topics:
Understanding Received Signal Strength on page 67
Estimating Wireless Cable Modem to Wireless Client Distances on page 67
Selecting a Wireless Channel on page 69
MAC Addresses
Defines the MAC addresses. Note: You may cut and paste
MAC addresses from the connected clients list at the bottom
of the screen.
Apply
Saves changes when clicked.
Connected Clients
Lists wireless clients currently connected listed by MAC
address.
MAC Address
– Displays the MAC addresses entered in
the MAC Addresses field (see above).
Age(s)
– Displays the duration since the wireless client’s
polled values were sent to the device. The values include
all information shown on this screen. The lower the
number, the more current its data.
RSSI(dBm)
– Displays the received signal strength from
the device to the wireless cable modem. This value is
commonly used to assist in troubleshooting wireless
performance issues. A signal strength between 0dBm
and -65dBm is considered optimal. Levels of -66dBm and
lower (for example, -70, -80, etc.) have a downward
impact on wireless data throughput. Refer to
on page 66
for more information.
IP Address
– Displays the IP address assigned to this
wireless client.
Host Name
– Displays the host name of the wireless
client.
Mode
– Indicates the applicable 802.11a/b/g/n standard
used by the connected client device.
Speed (kbps)
– Displays the maximum theoretical link
speed negotiated
between the wireless gateway and the
client. This does not include the overhead associated with
encryption, and so on. For example, actual speeds with
WEP encryption enabled are typically less than half of the
negotiated link speed.
TKIP encryption can also affect
performance. AES is the most efficient and secure with
the highest throughput possible. You can disable WMM if
throughput on some client adaptors is adversely affected.
