No WAN connection is established

After start-up the router automatically attempts to connect to the DSL pro-
vider. During this process, the LED responsible for monitoring the Internet
connection will blink green.If successful, the LED will switch over to steady
green. If, however, the connection can't be established, the Online-LED will
light up red. The reason for this is usually one of the following:
Problems with the cabling?
Only the cable provided with your device should be used to connect to DSL.
This cable must be connected to the Ethernet port of your broadband access
device. The WAN-LED must light green indicating the physical connection.
Has the correct transfer protocol been selected?
The transfer protocol is set along with the basic settings. The basic setup wiz-
ard will enter the correct settings for numerous DSL providers automatically.
Only if your DSL provider is not listed, you will have to enter manually the pro-
tocol being used. In any case, the protocol that your DSL provider supplies you
with should definitely work.
You can monitor and correct the protocol settings under:

DSL data transfer is slow

The data transfer rate of an broadband (Internet) DSL connection is dependent
upon numerous factors, most of which are outside of one's own sphere of
influence. Important factors aside from the bandwidth of one's own Internet
connection are the Internet connection and current load of the desired target.
Numerous other factors involving the Internet itself can also influence the
transfer rate.
