Possible solutions

No LEDs are lit or 
flashing

Make sure the SpeedTouch™ is plugged into an 
electrical outlet.

Make sure you are using the correct power supply for 
your SpeedTouch™ device, that is a 15V AC power 
adapter, like the one provided.

Make the SpeedTouch™ is powered on. 

Unplug the SpeedTouch™, reboot your computer and 
then plug the SpeedTouch™ back in.

DSL LED is flashing 
green or no DSL 
LED

Your DSL service is unable to synchronise.

Ensure the SpeedTouch™ is plugged into the DSL-
enabled phone line.

Ensure micro-filters have been correctly fitted (if not, 
there is a big chance you also have a bad regular 
telephone service).

Make sure you use the right power supply (15V AC).

Make sure that the correct SpeedTouch™ variant is 
used for your DSL service (ISDN/POTS).

If you have previously had a working connection, call 
your ISP to check for service outages.

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

Make sure the Ethernet NIC driver is correctly installed 
and enabled on your computer. Power safe options for 
the Ethernet NIC should preferably be disabled.
