Hello,

My Speedport Pro is unable to establish a DSL tunnel. I am currently running on LTE . I've tried to reset the device multiple times and reestablishing the connection with no success. The device originally had three yellow lights and then went to one green and one yellow. I have entered in the correct DSL access data. Is my device faulty, is the telephone port bad, or is the DSL servers no good in my area? Please help.
