[1] FRITZ! Failsafe – Always online with the new fallback protection for your FRITZ!Box's internet connection

Fallback protection redefined:

With FRITZ! Failsafe – the FRITZ!Box's new fallback protection – FRITZ!Box users stay online at all times. If the fibre optic, DSL or cable connection becomes unstable or fails, FRITZ! Failsafe ensures the home network's internet connection via an alternative internet connection. FRITZ! Failsafe does this via fallback by using a substitute connection via a fallback device connected upstream from the FRITZ!Box as a reserve via a WAN, LAN or USB port. This device can be another FRITZ!Box, a USB mobile network dongle, or a smartphone in USB tethering mode. A particularly suitable fallback device would be a FRITZ!Box for a mobile network – for example, a FRITZ!Box 6860 5G, 6850 5G, 6850 LTE or 6820 LTE.

This feature is ideal for anyone who depends upon a reliable internet connection – whether in a home office or a retail store. Whether you're using it for a video conference or to connect to an accounting system, with FRITZ! Failsafe your internet connection is secure – no matter if an excavator or a storm is approaching.

 

[2] Optimized parental controls

A number of practical optimizations have been included in the first version of FRITZ! Lab. The parental controls now clearly display access profiles and the corresponding devices on one page. Tickets for online time are easier to find on a separate tab and the number of tickets was increased from 10 to 12. This makes managing family internet usage even simpler and more intuitive. Detail improvements were also made to the Online Monitor area. The line graphs have been color-optimized for an even clearer display, and the tooltip that is now is easier to read provides users with more information about the Online Meter.

 

[3] New upload sharing - Sharing files easier than ever

With the new upload sharing via FRITZ!NAS, sharing files has never been easier: Users can make a folder available via sharing link, allowing others to directly upload and download content perfect for collecting shared photos or documents. Thanks to the new function, it is no longer necessary to create a FRITZ!Box user with special write permission instead, all that is needed to allow friends and family to securely upload files is a single link.

 

[4] 7590 AX now also usable as a Mesh Repeater via Wi-Fi

You can configure your FRITZ!Box for use as a Mesh Repeater and use Wi-Fi or a network cable to integrate it into the Mesh of your FRITZ!Box with internet access (Mesh Master) to increase the range of your home network easily and efficiently.

As a Mesh Repeater, the FRITZ!Box automatically adopts all of the necessary settings from the Mesh Master (for example Wi-Fi access information, guest access, schedule) and creates an additional Wi-Fi network that enables your devices to connect to the home network. In addition, the telephone numbers entered in the Mesh Master can be activated for the Mesh Repeater and used by telephone devices configured in it.

A maximum of Wi-Fi 5 (5 GHz) and Wi-Fi 4 (2.4 GHz) can be used for the connection to the Mesh Master.

[5] More possibilities in the smart home

The update also brings additional control functions for the FRITZ!DECT 440 smart switch. Now all the functions that could be configured directly on the radiator control FRITZ!Smart Thermo 302 can also be controlled with the smart switch. In addition, it now offers more comprehensive options for lighting control. Besides switching on and off and dimming, it can now be used to change the color and color temperature. In addition, routines can now be activated and deactivated directly using the FRITZ!Smart Control 440. Routines can also be triggered by a call, reaching a target temperature, activating the boost or antifreeze function, as well as by important events on the FRITZ!Box. To make managing Wi-Fi even simpler, the FRITZ!Smart Control 440 can be used to switch off the main Wi-Fi network in addition to guest Wi-Fi.

 

[6] New Online Monitor with expanded functions

The new Online Monitor shows which network devices are using the internet most intensively.

The views for the 'Total' utilization, the 'Top Consumers' and the individual devices allow the display to be restricted to certain time periods. The display periods that can be selected are 10 minutes, one hour, one day, and two months, and now also the past two weeks.

The selection of network devices for which the utilization data are to be recorded and displayed has been simplified considerably in the new version, and is now performed completely in the Online Monitor.

[1] FRITZ! Failsafe – Always online with the new fallback protection for your FRITZ!Box's internet connection

Fallback protection redefined:

With FRITZ! Failsafe – the FRITZ!Box's new fallback protection – FRITZ!Box users stay online at all times. If the fibre optic, DSL or cable connection becomes unstable or fails, FRITZ! Failsafe ensures the home network's internet connection via an alternative internet connection. FRITZ! Failsafe does this via fallback by using a substitute connection via a fallback device connected upstream from the FRITZ!Box as a reserve via a WAN, LAN or USB port. This device can be another FRITZ!Box, a USB mobile network dongle, or a smartphone in USB tethering mode. A particularly suitable fallback device would be a FRITZ!Box for a mobile network – for example, a FRITZ!Box 6860 5G, 6850 5G, 6850 LTE or 6820 LTE.

This feature is ideal for anyone who depends upon a reliable internet connection – whether in a home office or a retail store. Whether you're using it for a video conference or to connect to an accounting system, with FRITZ! Failsafe your internet connection is secure – no matter if an excavator or a storm is approaching.

 

[2] Optimized parental controls

A number of practical optimizations have been included in the first version of FRITZ! Lab. The parental controls now clearly display access profiles and the corresponding devices on one page. Tickets for online time are easier to find on a separate tab and the number of tickets was increased from 10 to 12. This makes managing family internet usage even simpler and more intuitive. Detail improvements were also made to the Online Monitor area. The line graphs have been color-optimized for an even clearer display, and the tooltip that is now is easier to read provides users with more information about the Online Meter.

 

[3] New upload sharing - Sharing files easier than ever

With the new upload sharing via FRITZ!NAS, sharing files has never been easier: Users can make a folder available via sharing link, allowing others to directly upload and download content perfect for collecting shared photos or documents. Thanks to the new function, it is no longer necessary to create a FRITZ!Box user with special write permission instead, all that is needed to allow friends and family to securely upload files is a single link.

 

[4] More possibilities in the smart home

The update also brings additional control functions for the FRITZ!DECT 440 smart switch. Now all the functions that could be configured directly on the radiator control FRITZ!Smart Thermo 302 can also be controlled with the smart switch. In addition, it now offers more comprehensive options for lighting control. Besides switching on and off and dimming, it can now be used to change the color and color temperature. In addition, routines can now be activated and deactivated directly using the FRITZ!Smart Control 440. Routines can also be triggered by a call, reaching a target temperature, activating the boost or antifreeze function, as well as by important events on the FRITZ!Box. To make managing Wi-Fi even simpler, the FRITZ!Smart Control 440 can be used to switch off the main Wi-Fi network in addition to guest Wi-Fi.

 

[5] New Online Monitor with expanded functions

The new Online Monitor shows which network devices are using the internet most intensively.

The views for the 'Total' utilization, the 'Top Consumers' and the individual devices allow the display to be restricted to certain time periods. The display periods that can be selected are 10 minutes, one hour, one day, and two months, and now also the past two weeks.

The selection of network devices for which the utilization data are to be recorded and displayed has been simplified considerably in the new version, and is now performed completely in the Online Monitor.

Thanks to the new function, it is no longer necessary to create a FRITZ!Box user with special write permission instead, all that is needed to allow friends and family to securely upload files is a single link.

 

[4] 7590 AX now also usable as a Mesh Repeater via Wi-Fi

You can configure your FRITZ!Box for use as a Mesh Repeater and use Wi-Fi or a network cable to integrate it into the Mesh of your FRITZ!Box with internet access (Mesh Master) to increase the range of your home network easily and efficiently.

As a Mesh Repeater, the FRITZ!Box automatically adopts all of the necessary settings from the Mesh Master (for example Wi-Fi access information, guest access, schedule) and creates an additional Wi-Fi network that enables your devices to connect to the home network. In addition, the telephone numbers entered in the Mesh Master can be activated for the Mesh Repeater and used by telephone devices configured in it.

A maximum of Wi-Fi 5 (5 GHz) and Wi-Fi 4 (2.4 GHz) can be used for the connection to the Mesh Master.

Further information can be found at: https://en.fritz.com/faqs/setting-up-the-fritzbox-as-a-mesh-repeater/

[1] Substitute connection: Greater fallback protection for the internet connection

With the new failover protection, FRITZ!Box users can stay online at all times. If the fiber optic, DSL or cable connection is unstable or drops, any FRITZ!Box connected via WAN/LAN establishes a fallback connection via the mobile network. This feature is ideal for anyone who depends upon a reliable internet connection, be it in the home office or a retail store.

 

[2] Optimized parental controls

A number of practical optimizations have been included in the first version of FRITZ! Lab. The parental controls now clearly display access profiles and the corresponding devices on one page. Tickets for online time are easier to find on a separate tab and the number of tickets was increased from 10 to 12. This makes managing family internet usage even simpler and more intuitive. Detail improvements were also made to the Online Monitor area. The line graphs have been color-optimized for an even clearer display, and the tooltip that is now is easier to read provides users with more information about the Online Meter.

 

[3] New upload sharing - Sharing files easier than ever

With the new upload sharing via FRITZ!NAS, sharing files has never been easier: Users can make a folder available via sharing link, allowing others to directly upload and download content perfect for collecting shared photos or documents. Thanks to the new function, it is no longer necessary to create a FRITZ!Box user with special write permission instead, all that is needed to allow friends and family to securely upload files is a single link.

 

[4] 7590 AX now also usable as a Mesh Repeater via Wi-Fi

You can configure your FRITZ!Box for use as a Mesh Repeater and use Wi-Fi or a network cable to integrate it into the Mesh of your FRITZ!Box with internet access (Mesh Master) to increase the range of your home network easily and efficiently.

As a Mesh Repeater, the FRITZ!Box automatically adopts all of the necessary settings from the Mesh Master (for example Wi-Fi access information, guest access, schedule) and creates an additional Wi-Fi network that enables your devices to connect to the home network. In addition, the telephone numbers entered in the Mesh Master can be activated for the Mesh Repeater and used by telephone devices configured in it.

A maximum of Wi-Fi 5 (5 GHz) and Wi-Fi 4 (2.4 GHz) can be used for the connection to the Mesh Master.

Further information can be found at: https://en.fritz.com/faqs/setting-up-the-fritzbox-as-a-mesh-repeater/

 

[5] More possibilities in the smart home

The update also brings additional control functions for the FRITZ!DECT 440 smart switch. Now all the functions that could be configured directly on the radiator control FRITZ!Smart Thermo 302 can also be controlled with the smart switch. In addition, it now offers more comprehensive options for lighting control. Besides switching on and off and dimming, it can now be used to change the color and color temperature. In addition, routines can now be activated and deactivated directly using the FRITZ!Smart Control 440. Routines can also be triggered by a call, reaching a target temperature, activating the boost or antifreeze function, as well as by important events on the FRITZ!Box. To make managing Wi-Fi even simpler, the FRITZ!Smart Control 440 can be used to switch off the main Wi-Fi network in addition to guest Wi-Fi.

 

[6] New Online Monitor with expanded functions

The new Online Monitor shows which network devices are using the internet most intensively.

The views for the 'Total' utilization, the 'Top Consumers' and the individual devices allow the display to be restricted to certain time periods. The display periods that can be selected are 10 minutes, one hour, one day, and two months, and now also the past two weeks.

The selection of network devices for which the utilization data are to be recorded and displayed has been simplified considerably in the new version, and is now performed completely in the Online Monitor.

[1] FRITZ! Failsafe – Always online with the new fallback protection for your FRITZ!Box's internet connection

Fallback protection redefined:

With FRITZ! Failsafe – the FRITZ!Box's new fallback protection – FRITZ!Box users stay online at all times. If the fibre optic, DSL or cable connection becomes unstable or fails, FRITZ! Failsafe ensures the home network's internet connection via an alternative internet connection. FRITZ! Failsafe does this via fallback by using a substitute connection via a fallback device connected upstream from the FRITZ!Box as a reserve via a WAN, LAN or USB port. This device can be another FRITZ!Box, a USB mobile network dongle, or a smartphone in USB tethering mode. A particularly suitable fallback device would be a FRITZ!Box for a mobile network – for example, a FRITZ!Box 6860 5G, 6850 5G, 6850 LTE or 6820 LTE.

This feature is ideal for anyone who depends upon a reliable internet connection – whether in a home office or a retail store. Whether you're using it for a video conference or to connect to an accounting system, with FRITZ! Failsafe your internet connection is secure – no matter if an excavator or a storm is approaching.

 

[2] Optimized parental controls

A number of practical optimizations have been included in the first version of FRITZ! Lab. The parental controls now clearly display access profiles and the corresponding devices on one page. Tickets for online time are easier to find on a separate tab and the number of tickets was increased from 10 to 12. This makes managing family internet usage even simpler and more intuitive. Detail improvements were also made to the Online Monitor area. The line graphs have been color-optimized for an even clearer display, and the tooltip that is now is easier to read provides users with more information about the Online Meter.

To make managing Wi-Fi even simpler, the FRITZ!Smart Control 440 can be used to switch off the main Wi-Fi network in addition to guest Wi-Fi.

 

[5] New Online Monitor with expanded functions

The new Online Monitor shows which network devices are using the internet most intensively.

The views for the 'Total' utilization, the 'Top Consumers' and the individual devices allow the display to be restricted to certain time periods. The display periods that can be selected are 10 minutes, one hour, one day, and two months, and now also the past two weeks.

The selection of network devices for which the utilization data are to be recorded and displayed has been simplified considerably in the new version, and is now performed completely in the Online Monitor.

[1] Substitute connection: Greater fallback protection for the internet connection

With the new failover protection, FRITZ!Box users can stay online at all times. If the fiber optic, DSL or cable connection is unstable or drops, any FRITZ!Box connected via WAN/LAN establishes a fallback connection via the mobile network. This feature is ideal for anyone who depends upon a reliable internet connection, be it in the home office or a retail store.

 

[2] Optimized parental controls

A number of practical optimizations have been included in the first version of FRITZ! Lab. The parental controls now clearly display access profiles and the corresponding devices on one page. Tickets for online time are easier to find on a separate tab and the number of tickets was increased from 10 to 12. This makes managing family internet usage even simpler and more intuitive. Detail improvements were also made to the Online Monitor area. The line graphs have been color-optimized for an even clearer display, and the tooltip that is now is easier to read provides users with more information about the Online Meter.

 

[3] New upload sharing - Sharing files easier than ever

With the new upload sharing via FRITZ!NAS, sharing files has never been easier: Users can make a folder available via sharing link, allowing others to directly upload and download content – perfect for collecting shared photos or documents. Thanks to the new function, it is no longer necessary to create a FRITZ!Box user with special write permission – instead, all that is needed to allow friends and family to securely upload files is a single link.

 

[4] More possibilities in the smart home

The update also brings additional control functions for the FRITZ!DECT 440 smart switch. Now all the functions that could be configured directly on the radiator control FRITZ!Smart Thermo 302 can also be controlled with the smart switch.

[1] Substitute connection: Greater fallback protection for the internet connection

With the new failover protection, FRITZ!Box users can stay online at all times. If the fiber optic, DSL or cable connection is unstable or drops, any FRITZ!Box connected via WAN/LAN establishes a fallback connection via the mobile network. This feature is ideal for anyone who depends upon a reliable internet connection, be it in the home office or a retail store.

 

[2] Optimized parental controls

A number of practical optimizations have been included in the first version of FRITZ! Lab. The parental controls now clearly display access profiles and the corresponding devices on one page. Tickets for online time are easier to find on a separate tab and the number of tickets was increased from 10 to 12. This makes managing family internet usage even simpler and more intuitive. Detail improvements were also made to the Online Monitor area. The line graphs have been color-optimized for an even clearer display, and the tooltip that is now is easier to read provides users with more information about the Online Meter.

 

[3] New upload sharing - Sharing files easier than ever

With the new upload sharing via FRITZ!NAS, sharing files has never been easier: Users can make a folder available via sharing link, allowing others to directly upload and download content – perfect for collecting shared photos or documents. Thanks to the new function, it is no longer necessary to create a FRITZ!Box user with special write permission – instead, all that is needed to allow friends and family to securely upload files is a single link.

 

[4] More possibilities in the smart home

The update also brings additional control functions for the FRITZ!DECT 440 smart switch. Now all the functions that could be configured directly on the radiator control FRITZ!Smart Thermo 302 can also be controlled with the smart switch.

[1] Substitute connection: Greater fallback protection for the internet connection

With the new failover protection, FRITZ!Box users can stay online at all times. If the fiber optic, DSL or cable connection is unstable or drops, any FRITZ!Box connected via WAN/LAN establishes a fallback connection via the mobile network. This feature is ideal for anyone who depends upon a reliable internet connection, be it in the home office or a retail store.

 

[2] Optimized parental controls

A number of practical optimizations have been included in the first version of FRITZ! Lab. The parental controls now clearly display access profiles and the corresponding devices on one page. Tickets for online time are easier to find on a separate tab and the number of tickets was increased from 10 to 12. This makes managing family internet usage even simpler and more intuitive. Detail improvements were also made to the Online Monitor area. The line graphs have been color-optimized for an even clearer display, and the tooltip that is now is easier to read provides users with more information about the Online Meter.

 

[3] New upload sharing - Sharing files easier than ever

With the new upload sharing via FRITZ!NAS, sharing files has never been easier: Users can make a folder available via sharing link, allowing others to directly upload and download content – perfect for collecting shared photos or documents. Thanks to the new function, it is no longer necessary to create a FRITZ!Box user with special write permission – instead, all that is needed to allow friends and family to securely upload files is a single link.

 

[4] More possibilities in the smart home

The update also brings additional control functions for the FRITZ!DECT 440 smart switch. Now all the functions that could be configured directly on the radiator control FRITZ!Smart Thermo 302 can also be controlled with the smart switch.

The update also brings additional control functions for the FRITZ!DECT 440 smart switch. Now all the functions that could be configured directly on the radiator control FRITZ!Smart Thermo 302 can also be controlled with the smart switch. In addition, it now offers more comprehensive options for lighting control. Besides switching on and off and dimming, it can now be used to change the color and color temperature. In addition, routines can now be activated and deactivated directly using the FRITZ!Smart Control 440. Routines can also be triggered by a call, reaching a target temperature, activating the boost or antifreeze function, as well as by important events on the FRITZ!Box. To make managing Wi-Fi even simpler, the FRITZ!Smart Control 440 can be used to switch off the main Wi-Fi network in addition to guest Wi-Fi.

 

[3] New Online Monitor with expanded functions

The new Online Monitor shows which network devices are using the internet most intensively.

The views for the 'Total' utilization, the 'Top Consumers' and the individual devices allow the display to be restricted to certain time periods. The display periods that can be selected are 10 minutes, one hour, one day, and two months, and now also the past two weeks.

The selection of network devices for which the utilization data are to be recorded and displayed has been simplified considerably in the new version, and is now performed completely in the Online Monitor.

[1] Optimized parental controls

A number of practical optimizations have been included in the first version of FRITZ! Lab. The parental controls now clearly display access profiles and the corresponding devices on one page. Tickets for online time are easier to find on a separate tab and the number of tickets was increased from 10 to 12. This makes managing family internet usage even simpler and more intuitive. Detail improvements were also made to the Online Monitor area. The line graphs have been color-optimized for an even clearer display, and the tooltip that is now is easier to read provides users with more information about the Online Meter.

 

[2] New upload sharing - Sharing files easier than ever

With the new upload sharing via FRITZ!NAS, sharing files has never been easier: Users can make a folder available via sharing link, allowing others to directly upload and download content perfect for collecting shared photos or documents. Thanks to the new function, it is no longer necessary to create a FRITZ!Box user with special write permission instead, all that is needed to allow friends and family to securely upload files is a single link.

 

[3] More possibilities in the smart home

The update also brings additional control functions for the FRITZ!DECT 440 smart switch. Now all the functions that could be configured directly on the radiator control FRITZ!Smart Thermo 302 can also be controlled with the smart switch. In addition, it now offers more comprehensive options for lighting control. Besides switching on and off and dimming, it can now be used to change the color and color temperature. In addition, routines can now be activated and deactivated directly using the FRITZ!Smart Control 440. Routines can also be triggered by a call, reaching a target temperature, activating the boost or antifreeze function, as well as by important events on the FRITZ!Box. To make managing Wi-Fi even simpler, the FRITZ!Smart Control 440 can be used to switch off the main Wi-Fi network in addition to guest Wi-Fi.

 

[4] New Online Monitor with expanded functions

The new Online Monitor shows which network devices are using the internet most intensively.

The views for the 'Total' utilization, the 'Top Consumers' and the individual devices allow the display to be restricted to certain time periods. The display periods that can be selected are 10 minutes, one hour, one day, and two months, and now also the past two weeks.

The selection of network devices for which the utilization data are to be recorded and displayed has been simplified considerably in the new version, and is now performed completely in the Online Monitor.

Release Notes

The latest lab file on our download server, "fritzrepeater-XXXX-Labor-xxxx.zip", contains

  • the lab version for your FRITZ!Repeater
  • this "infolab-en.txt" file with important information on this lab version
  • information, feedback options, and the file at en.fritz.com/fritz-lab

New and improved with FRITZ!OS 8.10

  • NEW: Smart Networking (1)
  • NEW: Simplified access to the user interfaces of FRITZ!Repeaters (2)
  • several corrections and stability improvements

(1) Smart Networking

In a home network consisting of a FRITZ!Box and more than one FRITZ!Repeater, the W-Fi connections of the repeaters are re-evaluated and optimized whenever changes are made in the home network or a repeater is restarted. Example: A FRITZ!Repeater is already connected to the home network. A second FRITZ!Repeater is added and connected directly to the FRITZ!Box. It can then be moved and plugged into the desired location. The repeaters now re-evaluate the situation and decide whether the new repeater should connect to the first repeater, or whether it should remain connected to the FRITZ!Box.

Requirement: FRITZ!OS 8.10 is installed on the FRITZ!Box and all of the FRITZ!Repeaters. This option can be disabled in the FRITZ!Box user interface under 'Home Network > Mesh > Mesh Settings'.

(2) Simplified access to the user interfaces of FRITZ!Repeaters

When switching from the FRITZ!Box user interface to the user interface of a FRITZ!Repeater in the Mesh, it is not necessary to re-enter any login data (single-sign-on).

Requirement: FRITZ!OS 8.10 is installed on the FRITZ!Box and all of the FRITZ!Repeaters.
