[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.

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.

Ausfallschutz neu definiert:

Mit FRITZ! Failsafe - dem neuen Ausfallschutz der FRITZ!Box - bleiben FRITZ!Box-Anwender immer online. Sollte die Glasfaser, DSL- oder Kabelverbindung instabil sein oder ausfallen, stellt FRITZ! Failsafe die Internetanbindung des Heimnetzes über eine alternative Internetverbindung sicher. FRITZ! Failsafe nutzt dazu via Fallback eine Ersatzverbindung über ein der FRITZ!Box per WAN-, LAN- oder USB-Port als Reserve vorgeschaltetes Ausfallschutzgerät. Das kann eine weitere FRITZ!Box, ein USB-Mobilfunkstick oder ein Smartphone im USB-Tetheringmodus sein. Als Ausfallschutzgerät eignet sich dabei insbesondere eine FRITZ!Box für Mobilfunk - wie z.B. eine FRITZ!Box 6860 5G, 6850 5G, 6850 LTE oder 6820 LTE.

Dieses Feature ist ideal für alle, die auf eine zuverlässige Internetverbindung angewiesen sind - sei es im Homeoffice oder in Ladengeschäften. Ob Videokonferenz oder Anbindung des Abrechnungssystems - mit FRITZ! Failsafe ist Ihre Internetverbindung sicher - ganz gleich ob ein Bagger oder ein Gewitter naht.

[2] Vereinfachte Bedienung der Kindersicherung

Mit der ersten Version des FRITZ! Labors erhält die Benutzeroberfläche der FRITZ!Box eine Reihe praktischer Optimierungen.

Die zumindest bei Eltern beliebte Kindersicherung zeigt nun die Zugangsprofile sowie die zugehörigen Geräte übersichtlich auf einer Seite an. Die Tickets für die Online-Zeit sind über einen eigenen Tab besser auffindbar und wurden von 10 auf 12 erhöht. Damit wird die Verwaltung der familiären Internetnutzung noch einfacher und intuitiver.

Mit FRITZ!OS 8 wurde der Online-Monitor vorgestellt, der nun ebenfalls Detailverbesserungen erhalten hat. So wurden die Linien-Grafiken für eine noch übersichtlichere Darstellung farblich optimiert und ein besser lesbarer Tooltipp gibt den Anwendern mehr Informationen zum Online-Monitor.

[3] Neue Upload-Freigaben - Teilen von Dateien so einfach wie nie

Mit der neuen Upload-Freigabe über FRITZ!NAS wird das Teilen von Dateien so einfach wie nie: Nutzer können einen Ordner per Freigabe-Link zugänglich machen, sodass andere direkt Inhalte hoch- und herunterladen können - perfekt zum Sammeln gemeinsamer Fotos oder Dokumente.

Dank der neuen Funktion entfällt die bisher notwendige Einrichtung eines eigenen FRITZ!Box-Benutzers mit speziellen Schreibrechten - stattdessen genügt ein einziger Link, um den sicheren Dateiupload für Freunde und Familie zu ermöglichen.

[4] 7590 AX erstmalig auch als Mesh Repeater über WLAN einsetzbar

Sie können Ihre FRITZ!Box für den Betrieb als Mesh Repeater einrichten und per WLAN oder über ein Netzwerkkabel ins Mesh Ihrer FRITZ!Box mit Internetzugang (Mesh Master) einbinden, um die Reichweite Ihres Heimnetzes einfach und effizient zu erhöhen.

Die FRITZ!Box übernimmt als Mesh Repeater automatisch alle erforderlichen Einstellungen des Mesh Masters (z.B. WLAN-Zugangsdaten, Gastzugang, Zeitschaltung) und erstellt ein weiteres Funknetz, über das sich Ihre Geräte mit dem Heimnetz verbinden können.

Zusätzlich können die im Mesh Master angelegten Rufnummern für den Mesh Repeater freigeschaltet und mit den dort eingerichteten Telefoniegeräten genutzt werden.

Maximal kann Wi-Fi 5 (5 GHz) und Wi-Fi 4 (2.4 GHz) für die Anbindung an den Mesh Master genutzt werden.

Weitere Informationen finden Sie unter: https://fritz.com/service/mesh/faqs/fritzbox-als-mesh-repeater-einrichten/

[5] Mehr Möglichkeiten im Smart Home

Das Update bringt auch erweiterte Steuerungsmöglichkeiten für den Mehrfachtaster FRITZ!Smart Control 440. Alle Funktionen, die bisher direkt am Heizkörperregler FRITZ!Smart Thermo 302 einstellbar waren, lassen sich nun auch mit dem Taster regeln. Darüber hinaus bietet er umfassendere Optionen für die Lichtsteuerung. Neben dem Ein- und Ausschalten sowie Dimmen können jetzt auch Farb- und Farbtemperatureinstellungen vorgenommen werden. Zusätzlich lassen sich Routinen direkt über den FRITZ!Smart Control 440 aktivieren und deaktivieren.

Routinen können außerdem durch einen Anruf, das Erreichen der Soll-Temperatur, die Aktivierung der Boost- oder Frostschutzfunktion sowie durch wichtige Ereignisse der FRITZ!Box ausgelöst werden.

Für noch mehr Komfort in der WLAN-Verwaltung ist es nun möglich, nicht nur das Gast-WLAN, sondern auch das Haupt-WLAN über den FRITZ!Smart Control 440 ein- und auszuschalten.

[6] Neuer Online-Monitor mit funktionalen Erweiterungen

Der neue Online-Monitor zeigt, welche Netzwerkgeräte das Internet am intensivsten nutzen.

Die Ansichten für die Auslastung "Insgesamt", die "Top-Verbraucher" und die Einzelgeräte erlauben das Eingrenzen auf bestimmte Zeitspannen. Die auswählbaren Zeiträume von 10 Minuten, einer Stunde, einem Tag und zwei Monaten wurde ergänzt um den Zeitraum der letzten zwei Wochen.

Die Auswahl der Netzwerkgeräte, für die Auslastungsdaten erfasst bzw. angezeigt werden sollen, ist mit der neuen Version deutlich vereinfacht worden und kann jetzt komplett im Online-Monitor erfolgen.

• Improved Online time for a network device with restricted online time now can also be extended for 45 minutes directly in the parental controls
• Improved Reworked diagrams and colors in the Online Monitor

Wi-Fi:

• Changed Incongruous information text for configuration of the Wi-Fi guest access on the Mesh Repeater removed

DECT/FRITZ!Fon:

• Improved Podcasts can now be continued after interruption

Home Network:

• Fixed In special scenarios it was possible for the IP address 192.168.178.1 to be displayed for a repeater in the home network instead of its own address

Mobile Network:

• Improved Support for USSD over IMS

USB:

• Improved Simplified generation of sharing links

[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.

[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.

[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] 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.

USB:

• Improved Simplified generation of sharing links

[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.

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).

We appreciate any feedback from our users, which can be submitted at: en.fritz.com/fritz-lab. This page also lists all of the current FRITZ! Lab versions with corresponding feedback areas.

Before you start testing the Lab version

1) You haven't installed the latest firmware for your FRITZ!Box yet? You first need to update the firmware to the latest release.

2) Save your current settings under "System / Backup". The saved settings will be needed if you want to switch back from the Lab firmware back to the release firmware.

Testing the Lab version

Once the latest FRITZ!OS version has been installed on your FRITZ!Repeater and you've saved your current settings, you can begin testing.

1) Unzip the "fritzrepeater-yyyy-LabBETA-xxxxx.zip" file.

2) Use the FRITZ!Repeater user interface to install the update:

• Select "View: Advanced" in the footer.
• Click "Update" in the "System" menu.
• Switch to the "FRITZ!OS File" tab.
• Follow the instructions displayed on the screen.
• Enter the path to the Lab firmware and the name of the Lab file (FRITZ.Repeater_xxxx-0x.xx-xxxxx-Labor.image) in the input field. 3) The Lab version is installed on the FRITZ!Repeater. The FRITZ!Repeater will then restart.

Restoring your device to how it was before testing

You can switch back to the official FRITZ!OS at any time under "System > Update > FRITZ!OS Version" or reset the FRITZ!Repeater back

to the official FRITZ!OS using the enclosed Windows program "recover.exe" (included in the Lab package).

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

• the lab version for your FRITZ!Powerline-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)
• Improved: Information on saving energy displayed when setting reduced bandwidth/SISO
• 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.
