9 Advice & assistance
See this chapter for first-aid assistance if some of the typical problems should
occur.
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 LAN LED does not illuminate. 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 The LED for
the WAN connection must illuminate in green to show that it is physically con-
nected.
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
yourself. The protocol specified by your DSL provider should work without pro-
blem.
You can check and adjust your protocol settings under:
Configuration tool
LANconfig
WEBconfig
9.2
Slow DSL transmission
The speed of data transmission over an (Internet) DSL connection depends on
a number of factors, most of which are beyond the influence of normal users.
Along with bandwidth of your provider's connection, of decisive importance
is the provider's Internet connection and the load on the target Web page.
Several other factors in the Internet itself can also influence the transmission
speeds.
