Product behaviour

The signal 

 does not switch on

• Make sure that the electrical power supply is plugged into a wall 

outlet

• Make sure that the coaxial jack of the electrical power supply adapter 

is plugged into your ADSL Wireless Base Station

• Make sure you are using the correct power supply for your Wireless 

Modem Router

• Make sure that the power switch of your ADSL Wireless Base Station 

is ON

• However, if your ADSL Wireless Base Station power if OFF after 

running for a while, check for power loss or overcharge. (If your wall 
outlet has a switch is it in position ON ?)

• If you still cannot isolate the problem, then the external power supply 

may be defective. In this case, contact Technical Support for 
assistance

The signal 

 is OFF

• Make sure that the telephone cable (RJ11) is plugged into the ADSL 

port of your ADSL Wireless Base Station and to your telephone wall 
outlet or distributed filter.

• Make sure that your landline works correctly. You can connect 

another telephone in the place of your current product. If you do not 
have tonality, the problem comes from your telephone line.

The signal 

 is always OFF

• Confirm with your Internet Service Provider that your Internet 

service is active

• Confirm your Internet setting with your Internet Service Provider

The signals 

 do not switch ON. Cannot ping the 

ADSL Wireless Base Station from the attached LAN.

• If you are using the Ethernet connection, verify that your TCP/IP is 

properly installed and configured on your PC.

• Make sure the Ethernet cable (RJ45) is firmly connected to your 

ADSL Wireless Base Station.

• Make sure you are using the correct cable type for your Ethernet 

equipment

• Verify that the IP address is properly configured. For most 

applications, you should use the ADSL Wireless Base Station DHCP 
function to dynamically assign IP address to hosts on the attached 
LAN. However, if you manually configure IP address on the LAN, 
verify that the same network address and subnet mask are used for 
both the ADSL Wireless Base Station and any attached LAN devices.

The Wireless network is often interrupted

• Move your Wireless PC closer to the ADSL Wireless Base Station to 

find a better signal. If the signal is still weak, you can change the angle 
of the antenna. There may be interference, possibly caused by 
microwave ovens, a Wireless TV link or wireless phones. Adapt the 
location of the interference sources or of the ADSL Wireless Base 
Station.

• You can change the wireless channels on the ADSL Wireless Base 

Station. See webpage “Channel and SSID”.

The Wireless Router is hot

• This is a normal behaviour
• Make sure to never cover the cooling slots
