Introduction

Fritz!Box is a very powerful DSL Wireless Router with several unique features:

  • Acts as a private telephone exchange for several telephones.
  • Supports VOIP Internet Telephony from any attached phone.
  • Supports IEEE 802.11g++ for added range and speed.
  • Excellent DSL throughput, even at high bit rates.
  • Traffic Shaping allocates DSL bandwidth fairly amongst applications.
  • Functionality can be extended by starting programs on a USB stick.
  • NAT32 Builds 1046 and later have Fritz!Box control and configuration support.

    Tips and Tricks

  • When using a phone with the Fritz!Box, you may hear a continuous buzzing noise when you try to make a call. This is mains hum caused by an earth loop of some sort. To get rid of it, substitute a normal CAT5 unshielded twisted pair Ethernet cable for the red shielded cable that came with the box.
  • To turn on the Telnet Server in the Fritzbox, pick up your phone and then type: #96*7*
  • Click to run the Windows Telnet Client.
  • To start the Telnet Server when your Fritz!Box boots, enter the following commands:
    echo '#!/bin/sh'>/var/rc.user
    echo '/usr/sbin/telnetd -l /sbin/ar7login'>>/var/rc.user
    cat /var/rc.user > /var/flash/debug.cfg
    
  • The sequence #96*8* turns off the Telnet Server.
  • To install and start an FTP Server on your Fritz!Box, see Tuning and Hacking the Fritz!Box (English translation coming soon).
