Unless you have been with TF for ages, like more than 5 years, you are probably not setting this router up correctly- you seem to be configuring a static IP address and these have not been provided by TF for quite a long time AFAIK.
Look at this site:
»www.adslzone.net/datosconexion.h ··· ion.html
and use the connection data for Telefonica Espana (dinamica).
Hope that helps
