9 Troubleshooting

In this chapter, you will find suggestions and assistance for a few common dif- ficulties.

9.1No WAN connection is established

After start-up the router automatically attempts to connect to the access pro- vider. During this process, the Online LED 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 the WAN. This cable must be connected to the Ethernet port of your broadband access device. The WAN link LED must light green indicating the physical con- nection.

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:
