the
device is powered
on.
Make sure to use the power adapter included in the
package. Make sure that the adapter is connected properly
to the device and power outlet.
DSL indicator is OFF
when the telephone
line is connected.
Make sure to use standard telephone lines (e.g., the
companion telephone line). Make sure that the lines
are connected properly. Check all the port connections.
Wait for 60 seconds for the device to establish an ADSL
connection.
When
the
telephone line is
connected,
DSL
indicator alternates
between slow and
fast flashing.
It indicates the connection failure between the device and
the office-end DSLAM. Please make sure that the lines are
connected properly. If a telephone is required to be installed
in front of the splitter, make sure to install a voice filter
properly.

Problem
Troubleshooting
LAN indicator is
OFF
when
the
Ethernet cable is
connected.
Make sure that the Ethernet cable is connected properly to
the computer and the W300. Make sure that the device and
computer are all powered on.
WLAN unable to be
connected
Make sure that the WLAN indicator is ON. Make sure that
the wireless NIC is set properly. Check the network name,
encryption mode, and encryption key to see whether they
match the settings of the W300.
PC unable to access
the network
Use the ping command to check if the IP address of the
network port of the W300 (192.168.1.1 by default) can
be pinged from the computer. If it cannot be pinged
successfully, check the Ethernet connection and see if
the indicator status is normal.
It is recommended that the local IP address and DNS
server address are set to be obtained automatically.
It is recommended to close all the running firewall and
VPN software.
Disable the proxy server setting of the web browser
(e.g., IE).
The failure reason may be that the office-end devices
of the ADSL service provider are being upgraded or in
maintenance.
