Priorities in WiFi
With the FRITZ!OS 6.80 update users can be sure to surf, stream or chat without interference even if the guest network is highly used. So you can decide which transmission rates you and your guests are entitled to. If the FRITZ!Box owners are not online, the guests can enjoy higher data rates.

Even better and easier: MyFRITZ! for browser and app
Following the fritz.box user interface - the window to the FRITZ!Box - with FRITZ!OS 6.83 the user interfaces of the MyFRITZ! service (myfritz.net) and FRITZ!NAS now also appear in a responsive design and adjust to any display size. Using the MyFRITZ!App 2 (for Android) users have convenient access to their FRITZ!Box - at home and from anywhere else. With a single swipe you can establish a secure connection to your home network and access your FRITZ!Box and connected devices from on the go.

On the safe side: strong passwords and settings requiring confirmation
The saving of backup files and the changing of certain settings are even safer now, as a new function implements an additional confirmation that can only be verified where the FRITZ!Box is located (two-factor authentication). Attempts to log in with wrong user data are recorded as an event. Numerous other FRITZ!OS 6.83 upgrades provide the FRITZ!Box with the latest security standards. With every large update AVM always advises to install the latest version of FRITZ!OS for optimum security and best network synchronization.

Approve access from the Internet for online games, gaming consoles or IP devices
Devices connected to the FRITZ!Box are safe from unauthorized access from the Internet. However, certain applications such as online games or devices like IP cameras or gaming consoles sometimes need to be accessible for others over the Internet. FRITZ!Box users can enable such connections through port sharing. Now it's also possible to allow certain devices to control port sharing automatically. With FRITZ!OS 6.83 all shared ports (IPv4, IPv6, MyFRITZ! or autonomous) can be viewed and configured at once. Users can find an overview of all shared ports with their connected home network devices in the menu at "Internet" "Permit Access". Settings for parental controls can also be used with pure IPv6 devices with the new FRITZ!OS 6.80.
