5 Configuring the computer's firewall
A firewall can interfere with the communication between the computer and the FRITZ!Box:
- Configure the firewall on the computer so that it allows connections from the computer to the FRITZ!Box. Refer to the manufacturer of the firewall for information on how to set it up, for example consult the manual.
6 Installing the latest software for network adapters
