Step 3
Ensure that the security mode of the WLAN is set to
WPA2-PSK
or
WPA-PSK/WPA2-PSK
. Note that the WPS
function of the HG630b is forcibly disabled if the WEP
encryption is used for the WLAN.
Step 4
Check the positions of the HG630b and computer. Ensure
that they are far from electric appliances that generate
strong magnetic or electric fields, such as microwave
ovens, refrigerators, and cordless telephones.
Step 5
Place the HG630b and the computer in an open space.
Although radio signals can pass through obstacles, passing
through too many obstacles, such as walls and columns
may negatively impact the transmission of WLAN radio
signals.
What can I do if I cannot access the Internet through a wireless
network adapter?
Step 1
Ensure that the power cables and telephone lines of the
HG630b are connected properly.
Step 2
Check whether the
WLAN
indicator of the HG630b is on.
If the
WLAN
indicator is off, the WLAN function of the HG630b is
disabled. If this is the case, enable the WLAN function.
For details about how to enable the WLAN function, see section 5.1
"Enabling or Disabling the WLAN Function."
Step 3
Look at the description of the wireless network adapter that
is installed on the computer and check whether the wireless
network adapter supports the 802.11b, 802.11g, or
802.11n protocols.
If the wireless network adapter does not support the preceding
protocols, replace it.
Step 4
Check whether the driver for the wireless network adapter
is installed on the computer properly.
If the driver is installed improperly, re-install it.
Step 5
Check whether the computer can receive signals from the
WLAN.
Using a computer that runs Windows XP as an example,
