New features for the FRITZ!Box: New design for FRITZ!OS 6.50, with better overview of the home network and over 120 innovations
The latest update offers a redesigned user interface at http://fritz.box, optimized for smartphones, tablets and notebooks. In the browser it adjusts flexibly to the different display sizes. The user interface also received a fresh new look. The menu items and their arrangement remain familiar to users.
The extensive home network overview of all connected devices is also new. These include all wireless, LAN, powerline and USB devices. At a single glance users can see whether their connected FRITZ! products are equipped with the latest version of FRITZ!OS. You can start updates directly from here.
With the new FRITZ!OS you can also use helpful analyses of your wireless LAN environment. Under "Wireless / Radio Channel" the loading of the radio channel currently in use is shown over time for the 2.4-GHz and the 5-GHz frequency band. The lower the loading of the radio channel, the better the potential data throughput there.
News for parental controls: Tickets can be issued for each device to extend surfing time by 45 minutes. When online time has been exhausted, tickets can be redeemed on the Information page on blocked Internet use in the browser.
By going to http://fritz.box/surf.lua with any network device, you can view the device's settings for Internet use and the amount of online time already used on the current day.
Since AVM also optimizes the security of the entire FRITZ! family with every new FRITZ!OS, it is advisable for every user to perform the update.
