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 Modem 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 Modem 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 Modem
Router is shipped with is channel 11; you may choose from several
other channels depending on your region. See the section on page 43
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.
