9.1

No WAN connection can be established

After starting, the router attempts automatically to connect to the Internet
provider. During this phase, the Internet-connection status LED blinks green.
If successful, this LED switches to constant green. If contact cannot be made,
the Online LED illuminates red. This is generally due to one of the following
causes:
Problems with the cabling?
For the DSL connection, use only the connector cable supplied. This cable
must be connected to the Ethernet connector of the DSL modem or the net-
work connector. The LED for the WAN connection must illuminate in green to
show that it is physically connected.
Is the correct transmission protocol selected?
The transmission protocol is defined with the basic settings. The Basic Settings
Wizard actually sets the correct protocol for a wide variety of DSL providers. If
your DSL provider is unknown to the Wizard you have to set the protocol your-
self. The protocol specified by your DSL provider should work without prob-
lem.
You can check and adjust your protocol settings under:
Configuration tool
LANconfig
WEBconfig

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.
