•
My wireless network performance is inconsistent.
•
Data transfer is sometimes slow.
•
Signal strength is poor.
•
Difficulty establishing and/or maintaining a Virtual Private
Network (VPN) connection.
Wireless technology is radio-based, which means connectivity
and the throughput performance between devices decreases
when the distance between devices increases° Other factors that
will cause signal degradation (metal is generally the worst culprit)
are obstructions such as walls and metal appliances° Note also
that connection speed may decrease as you move farther away from
the Router°
In order to determine if wireless issues are related to range, we
suggest temporarily moving the computer, if possible, five to 10 feet
from the Router°
Changing the wireless channel
—Depending on local wireless traffic
and interference, switching the wireless channel of your network can
improve performance and reliability° The default channel the Router
is shipped with is channel 11; you may choose from several other
channels depending on your region° See the section on page 52
entitled “Changing the Wireless Channel” for instructions on how to
choose other channels°
Limiting the wireless transmit rate
—Limiting the wireless transmit
rate can help improve the maximum wireless range and connection
stability° Most wireless cards have the ability to limit the transmission
rate° To change this property, go to the Windows Control Panel, open
“Network Connections” and double-click on your wireless card’s
connection° In the properties dialog, select the “Configure” button on
the “General” tab (Windows 98 users will have to select the wireless
card in the list box and then click “Properties”), then choose the
“Advanced” tab and select the rate property°
Wireless client cards are usually set to automatically adjust the
wireless transmit rate for you, but doing so can cause periodic
disconnects when the wireless signal is too weak; as a rule, slower
transmission rates are more stable° Experiment with different
connection rates until you find the best one for your environment°
Note that all available transmission rates should be acceptable for
browsing the Internet° For more assistance, see your wireless card’s
user manual°
