If the driver is improperly installed, install it properly.
5. Check whether the computer can receive the signals of a WLAN.
Take a computer that runs Windows XP as an example. To check whether
the computer can receive the signals of a WLAN, do as follows:
1) In the
Control Panel
window, double-click
Network Connections
to
display the
Network Connections
window.
2) In the
Network Connections
window, right-click
Wireless Network
Connection
and choose
View Available Wireless Network
.
If the computer cannot detect a WLAN, place the computer close to the
terminal and ensure that no obstacles such as cement or wooden walls are
present between the wireless client and the terminal.
6. Check whether the computer accesses the WLAN of the terminal
successfully.
Check the list of wireless network connections and ensure that the terminal
is connected to the WLAN.
7. Check whether you can use the PPP dialing software to dial successfully.
8. Try to access multiple Web sites to check whether the terminal can access
other Web sites.
If the terminal cannot access other Web sites either, restore the default
settings of the terminal. If the problem persists, contact your network
service provider.
What can I do if sometimes the terminal cannot access the
Internet through a wireless network adapter or if the WLAN
connection is unsteady?
1. Check the positions of your terminal and computer. Ensure that they are far
from the electric appliances such as microwave ovens, refrigerators, or
cordless telephones that generate strong magnetic or electric fields.
2. Place your terminal in an open position.
Although radio signals can pass through obstacles, the transmission effects
of WLAN radio signals are affected if radio signals pass through too many
obstacles such as cement or wooden walls.
3. Place your computer close to your terminal.
