Check whether the light for the port you are connected to is lit up on the router/HUB/switch. Unplug the Ethernet cable at both ends, then plug it back in again. Alternatively, use another port on the router. Disconnect the terminal briefly from the power supply.
Check your Internet access
Unplug your router from the power for a few moments, then plug it back in again and try to re-establish an Internet connection. If this does not work, please contact your provider.
If these measures do not have the desired effect, please contact our Support Team. You can find the telephone number in your documents.
