IS YOUR ETHERNET CABLE NOT LONG ENOUGH?
You can purchase longer cables from any good electronics store if the cable supplied
with your T-Gateway is not long enough. Keep in mind that longer cables can cause
slower internal connection speeds.
IS THE ETHERNET LIGHT NOT ON?
If the Ethernet indicator doesn't come on, check that the cable is plugged in firmly
at both ends.
Also check the device you are trying to connect to your Gateway is powered on and
ready to connect (see the device's manual for instructions).
If this doesn't help, you may have a fault in your device, your Gateway or the Ethernet
cable. Please contact us through one of the options in the 'More Help' section.
