TROUBLESHOOTING, SUPPORT, AND WARRANTY
My wireless network performance is slow, inconsistent,
suffers from weak signal, or I’m having difficulty maintaining a
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
within 10 feet from the Router if possible°
Changing the wireless channel—
Depending on local
wireless traffic and interference, switching the wireless
channel of your network can improve performance and
reliability° See the section titled “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 range and connection stability° Most wireless
cards have the ability to limit the transmission rate° To change this
property in Windows, 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, 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°
