FRITZ!OS PART 1
Once you login the web GUI you will be redirected to the overview screen from where you can test the current power consumption, check the current connections and used interfaces and see which devices are currently connected to the device. By default the FRITZ! OS (web GUI) is set on standard view (lower end of the screen) and so if you really want access to everything the FRITZ! Box 7490 has to offer i strongly suggest using advanced mode.
Through the Internet drop down menu you can check the utilization of your internet connection (there are a couple of nice graphs here) and the amount of data send and received, setup your connection (IPv6 is supported), set individual parental filters for all connected devices, enable/disable access to the FRITZ!Box 7490 from anywhere in the world via HTTPS and finally you can monitor your DSL connection from the most detailed information page I’ve ever seen used in a modem/router.
The Telephony drop-down menu can be used if you connect a phone with the device and allows you to check the calls list, configure the answering machine, access stored telephone numbers, setup the phone (or phones) as alarms, setup the fax function and also allows you to handle/redirect all incoming calls.
