Setting up the FRITZ!Box for use with a DSL modem
You can use your FRITZ!Box with an additional ADSL, SDSL, or VDSL modem on any DSL line. Since the FRITZ!Box establishes and controls its own internet connection over the DSL modem, all FRITZ!Box functions (such as firewall, parental controls) are also available without restriction in this operating mode.
Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.
1 Connecting the FRITZ!Box with a DSL modem
- Insert one end of a network cable into the 'WAN' port on the FRITZ!Box. Use the network cable supplied with the FRITZ!Box, for example.
- Insert the other end of the network cable into the LAN port on the DSL modem.
2 Configuring the internet connection in the FRITZ!Box
- Open the FRITZ!Box user interface.
- Enter the FRITZ!Box password given on the type label of the FRITZ!Box and click on 'Log In'.
- Click on 'Internet' and then on 'Account Information'.
- Select 'DSL or fiber optic modem' from the 'Internet connection via' drop-down list.
- If your internet service provider is displayed in the drop-down list, select your provider and enter the account information you received from the internet service provider in the corresponding fields.
- If your internet service provider is not displayed:
- Select 'other internet service provider'.
- Enter the account information you received from the internet service provider in the relevant fields. If account information is not required, enable the 'No' option.
- Enter the speeds of your internet connection in the 'Downstream' and 'Upstream' fields.
- If the internet service provider requires you to use a particular VLAN ID, click on 'Change Connection Settings', enable the 'Use VLAN for internet access' option, and enter the VLAN ID.
- If your internet service provider is not displayed:
- Click on 'Apply' to save the settings.
- Now the FRITZ!Box checks whether the internet connection can be established. Configuration is complete as soon as the message 'The internet connection check was successful' is displayed.
Note:If the internet connection check fails, your internet access may not have been activated yet, or the account information is incorrect. In this case, contact the internet service provider.
