10 Troubleshooting
In this chapter, you will find suggestions and assistance for a few common dif-
ficulties.
10.1
No DSL connection is established
After start-up the router automatically attempts to connect to the DSL provi-
der. During this process, the LAN-link LED will blink green. If successful, the
LED will switch over to steady green. If, however, the connection can't be esta-
blished, the LAN-link 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 LAN link 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
wizard will enter the correct settings for numerous DSL providers automati-
cally. Only if your DSL provider is not listed, you will have to enter manually
the protocol being used. In any case, the protocol that your DSL provider sup-
plies you with should definitely work.
You can monitor and correct the protocol settings under:
Configuration tool
LANconfig
WEBconfig
10.2
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.
