New features for Mesh

General information on Mesh is presented at

Enabling the Mesh Function

To check whether a FRITZ! product is enabled for Mesh, see the Mesh Overview of the FRITZ!Box (the Mesh Master) under " -> Home Network -> Mesh". Here the products in the Mesh are designated with a corresponding "Mesh active" symbol.

A FRITZ!WLAN Repeater or FRITZ!Powerline Adapter with FRITZ!OS 6.90 or higher installed can be enabled for Mesh in various ways:

  • If the product has the ex works settings configured and is being connected with the FRITZ!Box for the first time, it will be automatically enabled for Mesh.
  • If the product is already connected, but not enabled for Mesh, it is added to the Mesh by pressing a button on the product to be integrated and a button on the FRITZ!Box. On the FRITZ!Box, use the button that initiates WPS (depending on the model, press the "Connect" or "WPS" button briefly, or the "WLAN/WPS button for 6 seconds)

Detailed instructions, additional information and the answers to frequently asked questions about Mesh are presented at

Telephony Mesh and Smart Home Mesh

With FRITZ!OS 7.0, telephony and Smart Home are also compatible with the Mesh.

The connections of cordless telephones and Smart Home products are displayed in the FRITZ!Box Mesh Overview. You can use a second FRITZ!Box as Mesh repeater, and use telephones registered with the second FRITZ!Box with the numbers assigned in the first FRITZ!Box, the "Mesh Master".

Configuring a second FRITZ!Box as a Mesh repeater with the press of a button


  • Your existing FRITZ!Box supports Mesh (FRITZ!OS 6.90 or higher). This box is the Mesh Master.
  • The FRITZ!Box to be deployed as a Mesh repeater has been updated to FRITZ!OS 7.0 and you have restored its settings ex works. This box is to become the Mesh repeater.

Here's how:

  • Connect the LAN1 port of the Mesh repeater with the Master using a LAN cable
  • Initiate the Connect function on both boxes (7590: press the "Connect" button briefly; 7490: press and hold down the WLAN/WPS button for 6 seconds)

After the connection procedure is concluded, the second FRITZ!Box is ready for operation as a Mesh repeater. (It operates in "IP client" mode and, as a Mesh repeater, adopts the wireless LAN settings and other important settings from the FRITZ!Box).

Please note that this function can be used only if the second FRITZ!Box is permanently connected with the first box by LAN cable.

Instructions for configuring a FRITZ!Box connected via wireless LAN as a Mesh repeater are presented at

Transmit the telephone numbers of a Mesh Master to another FRITZ!Box in the home network

Once you have added an additional FRITZ!Box to the Mesh, you can configure it so that all telephone numbers are available on each FRITZ!Box. If your FRITZ!Box is connected with a landline, you can use the telephones connected to the second FRITZ!Box to make calls over the internet as well as on the landline. If the latest FRITZ!OS 7.0 is installed on both FRITZ!Boxes, the telephone numbers are transferred automatically in the Mesh once the "Telephony in the Mesh" option is enabled.

If the new FRITZ!Box is already part of the Mesh, or if you have already set up telephone numbers there, these telephone numbers must be deleted and one of the two FRITZ!Boxes must be restarted.

Then the new FRITZ!Box must be enabled for "Telephony in the Mesh". To do so proceed as follows:

  • Click on "Home Network" in the user interface of the Mesh Master.
  • Click on "Mesh" in the "Home Network" menu.
  • Click on the "Mesh Settings" tab.
  • In the "Use Telephony in the Mesh" section, click on the "Enable" link next to the Mesh repeater in question and then confirm this operation on the Mesh Master as well, if prompted to do so.

The telephone numbers are now distributed in the Mesh and can be assigned to your telephones and other terminal equipment for telephony (for instance, answering machines) on the FRITZ!Box.

Note: Telephony Mesh is not the same thing as DECT repeating, which requires the support of special hardware on the FRITZ!Box deployed as the Mesh Master. If you would like to use DECT repeating, you can purchase the FRITZ!DECT Repeater 100 from an electronics retailer.

Display of 802.11k and 802.11v support on wireless devices

FRITZ!OS now displays wireless devices that support the wireless standards 802.11k and 802.11v directly in the user interface. Both standards are already widespread for wireless devices and are important prerequisites for the further development of Mesh WiFi for the fastest, lowest-interference, and most convenient control of wireless devices in Mesh environments To find out whether your wireless devices offer support for the 11k and/or 11v standards, see the "Properties" under the Wireless / Radio Network menu, or use the "Edit" function to display the properties of each wireless device.

Additional Innovations in FRITZ!OS 7.0

What's new for the FRITZ! Hotspot

The new FRITZ!OS 7.0 vmakes setting up and using the FRITZ! Hotspot even easier. It's now even easier for users to choose whether the wireless guest access should be provided as an open hotspot, or encrypted as a private hotspot. If an open hotspot is chosen, the guests do not need to enter a security key. Cafés, doctor's offices and small businesses, as well as all FRITZ!Box users, can provide their customers and visitors an easy-to-use internet access that complies with the current legal regulations. Whether it's private or public hotspot, guests cannot access the home network, but surf using a second wireless LAN provided by the FRITZ!Box.

Secure and Complete Control

The operator of the hotspot can decide which applications can be used in the guest network and which are prohibited. Daily email messages notify the operator of the hotspot about which devices were registered in the radio network and when. Another advantage is the option to reserve bandwidth. This options allows you to specify how much of the data rate is reserved for their own wireless LAN and how much is available to their guests.

Individual & Convenient

The Welcome page of the FRITZ! Hotspot offers additional convenience. Cafés or businesses can greet their guests with a short welcome text, photo or logo. If desired, the guests can also be requested to consent to the terms of use for the hotspot. The hotspot is also available in locations where FRITZ!WLAN Repeaters or powerline devices supporting WiFi provide for better coverage.

Increased speed when using USB storage media with NTFS data systems

If you're using USB sticks or flash drives on your FRITZ!Box that are formatted with the data system NTFS, you can benefit from increased speed during transmission. You don't have to do anything - just continue to use the existing USB storage media as before. To check what data system is used, go to Home Network -> USB Storage Media in the FRITZ!Box user interface.

New security feature in the wireless LAN: "Protected Management Frames (PMF)"

FRITZ!OS now supports additional security during registration of devices with the wireless LAN. "Protected Management Frames" ("PMF" for short) offer additional protection for the wireless connection during the setup phase. PMF is standardized according to IEEE 802.11w-2009 and is automatically offered to or negotiated with wireless devices that support this technology. The new feature is available in the user interface under Wireless > Security > Additional Security Settings.

Support for Telekom SIP Trunking

With FRITZ!OS AVM 7.0 provides support for the SIP trunking technology from Deutsche Telekom. For a few months now, Deutsche Telekom has been offering its business clients a SIP Trunk standard, making it easy to switch from ISDN to IP-based ports. The FRITZ!Box supports up to 20 direct inward dialing (DID) numbers for telephones connected directly to the FRITZ!Box. If a user's phone tariff contains more than 20 direct inward dialing numbers, these can be used with an ISDN PBX (Private Branch Exchange) for the system connection via the FRITZ!Box's internal S0 interface. With FRITZ!OS 7.0, the FRITZ!Box supports the "Deutschland LAN SIP Trunk" and "Deutschland LAN SIP Trunk Pooling" tariffs.

Detailed configuration instructions are presented in the following guide:

MyFRITZ! access to your FRITZ!Box via internet now without security messages in the browser

When you access the user interface of your FRITZ!Box from the internet, a security warning may be displayed in the browser. The new FRITZ!OS version enables your FRITZ!Box to receive a SSL certificate for your MyFRITZ! address from the organization Browser access via the MyFRITZ! address to the interface of FRITZ!Box is no longer accompanied by a security warning, since most browsers trust the certificates from

Proceed as follows:

  1. First you need to register your FRITZ!Box with MyFRITZ! (
  2. Under "Internet / MyFRITZ! Account", enable the "Let's encrypt" optLet's Encryption.
  3. Confirm by clicking "Apply" and wait for the status "Certificate issued successfully".

Your FRITZ!Box has the certificate created for your MyFRITZ! address and uses it for browser access to this address, for example when you access your FRITZ!Box via your account on

It's also possible to send links for FRITZ!NAS file sharing (for example photos) to third parties, who'll have access without annoying certificate warnings. This way, FRITZ!NAS becomes an even greater alternative to cloud storage services.

Note: To receive the certificate, the TCP port 443 of your FRITZ!Box is open for a few minutes. The certificate is currently valid for 60 days and is then renewed by the FRITZ!Box. HTTPS access to your FRITZ!Box via public or local IP address, "" in the home network or over a DynDNS provider do not use the certificate from letsencrypt. MyFRITZ!App: After activation of the Let's Encrypt certificate in the FRITZ!Box, the MyFRITZ!App notifies you once about the change of the certificate fingerprint. Select "trust" to continue using the new certificate.

Option for assessing and, if necessary, remedying detected interference with VDSL from Powerline

In the Internet / DSL Information / Interference Resistance menu of the FRITZ!Box, any interference with VDSL that may have been caused by FRITZ!Powerline can be minimized. This process of checking and adjusting can take up to ten minutes. During this time, the load on the powerline connection may affect the network quality and internet connection. This procedure can be repeated to optimize the interaction of VDSL with a high-performance powerline installation step by step, and the adjustmented settings can be returned to their original configuration.

This option is available only if VDSL interference was detected that could have been caused by a FRITZ!Powerline product.

Support for DECT ULE/HAN FUN

DECT-ULE/HAN-FUN is a manufacturer-independent standard for Smart Home devices.

The following sensors passed testing with FRITZ!OS 7.0 to confirm that they work with HAN-FUN:

Used in combination with a FRITZ!Box and the FRITZ!DECT 200/210 smart plug, they can be used to realize the following scenarios:

  • Press wall switch => Outlet is switched => Light on/off
  • Motion sensor triggered => Light on in the home/garage/yard
  • Window sensor open/closed switches FRITZ!DECT 200 => connected humidifier / air purifier switches off/on Please note during installation: The Telekom app cannot be used to install SmartHome devices to be deployed with a FRITZ!Box. The HAN-FUN devices are connected (paired) with the FRITZ!Box via the DECT button. In addition to the AVM Smart Home devices, a maximum of ten HAN-FUN devices can be registered with a FRITZ!Box.
    After successful DECT pairing, the new devices are listed in the FRITZ!Box user interface (Home Network => Smart Home) as "HAN-FUN function xxx" and their properties can be configured accordingly.

Support for Speedphone 11 from Deutsche Telekom

With FRITZ!OS 7.0 it is possible to use a Speedphone 11 with advanced telephone functions with a FRITZ!Box. For this the software of the Speedphone 11 must be updated.

Please note: At the time of publication in July 2018, a corresponding update was forthcoming.

If the firmware version 4.01 is installed on your Speedphone 11, perform the following steps:

  1. Register the Speedphone 11 with the FRITZ!Box according to these instructions, during which the expanded security functions of the FRITZ!Box will be disabled briefly:
  2. If a new Speedphone firmware is available for updating, it will be offered automatically. Alterntively, you can perform a manual check via the menu.
  3. Once the firmware has been updated (> version 4.01), the security functions disabled in step one should be reactivated in the FRITZ!Box.
  4. Re-register the Speedphone 11 with the FRITZ!Box.

The Speedphone 11 is now available for telephone services with DECT encryption enabled. The following features were tested successfully:

  • caller ID display
  • caller ID
  • access to the FRITZ!Box address book
  • call list
  • use of the FRITZ!Box answering machine

Smart Home

  • NEW Display of temperature curve over the last 24h for devices with temperature sensor
  • NEW Group switching for radiator controls
  • NEW Switching of the FRITZ!DECT 200/210 smart plug by sounds, like clapping or knocking


  • NEW New convenience features added to user interface and optimized display on smartphones and tablets (responsive design)


  • NEW Password for registering an IP telephone with the FRITZ!Box must have at least eight characters. IP telephones with a shorter password will be disabled with this update.

  • NEW Text messages received at mobile communications dongles operating as a modem displayed as events

More wireless LAN speed through band steering

The new FRITZ!OS offers a leap of speed for WiFi with band steering. Many smartphones and tablets can transmit data on the 2.4-GHz-band and the 5-GHZ-band. If one band is working at a high capacity, the FRITZ!Box now automatically initiates a band switch. This way resources can be exploited better and data reach their destination faster and without interference. Band steering is possible for all FRITZ!Box models with dual-band Wireless AC+N (FRITZ!Box models 7580, 7490, 7560, 6490, 4040, 3490).

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. The new online monitor is also very handy, since it now displays the data rates of the guest access on top of the usual downstream rates for Internet and IPTV.

FRITZ!Fon: additional start screens and night service

FRITZ!Fon, the DECT telephone for FRITZ!Box, received new selectable start screens. Users now have their Smart Home products in direct view and can switch even easier. The analog clock displayed in white or black is also new. The new night service is dimming the display when the brightness in the room falls below the settings. The possibility to configure a call diversion with the FRITZ!Box can now also be used with any contact in the requested telephone book. Plus, the number of outgoing calls can be limited with FRITZ!OS 6.80.

Smart Home switch on sound

The smart plugs FRITZ!DECT 200 and DECT 210 can already be switched automatically at sunrise/sunset or according to an individual schedule via app or phone. Now another option was added: with FRITZ!OS 6.80 an acoustic sensor is activated locally in the smart plug. Lamps or other connected devices will then react to sounds like clapping or knocking. Another innovation is the display of the temperature measured over the last 24 hours in the FRITZ!Box user interface. Starting with FRITZ!OS 6.80, group switching can also be used for the new radiator control FRITZ!DECT 300.

Even better and easier: MyFRITZ! for browser and app

Following the user interface ? the window to the FRITZ!Box ? with FRITZ!OS 6.80 the user interfaces of the MyFRITZ! service ( 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 saved data, their call list or voice messages - at home and from anywhere else. Users will receive real time notifications via the app about missed calls or new voice messages. 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. Even Smart Home devices can be operated and switched directly via app or widget.

On the safe side: strong passwords and settings requiring confirmation

The configuration of new IP phones and call diversions as well as the saving of backup files is 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. On top of this, FRITZ!OS 6.80 makes sure that users assign a password with at least 8 digits when configuring an IP telephone or an IP intercom system via the FRITZ!Box. Numerous other FRITZ!OS 6.80 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.

FRITZ! convenience with DECT telephones from other manufacturers

With FRITZ!OS 6.80 DECT telephones that support the CAT-iq 2.0 standard offer many convenience features that come with FRITZ! telephony. For example, cordless telephones from other manufacturers can use one or more telephone books in the FRITZ!Box and users can get a quick overview with the call list.

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 6.80 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. ___

  • NEW Wizard for adopting telephone numbers when switching from landline to an IP-based line for Telekom and Vodafone
  • NEW Multiple telephone numbers can be added at one time for Telekom and Vodafone

New FRITZ!OS 6.30 for interoperability, convenience and security

This version of FRITZ!OS includes modifications to better support the latest services offered by Internet providers, especially for switching to IP-based lines, and improved interoperability on the DSL line.

The new FRITZ!OS makes it even easier to start off in the world of IP-based telephony on new Telekom and Vodafone connections. If the FRITZ!Box was previously used on a classic landline, a new wizard makes it possible to take all of your landline telephone numbers with you to the world of IP-based telephony.

The step to IP-based telephony is also much simpler for new customers. Using the wizard for setting up new telephone numbers up to 10 telephone numbers can be created at once. This benefits not only Telekom and Vodafone customers, but also any users of "other providers" who use a single password for all of their telephone numbers.

Vodafone customers can enjoy an extra improvement with the new FRITZ!OS. It is now even easier to reconfigure the Vodafone account data entered during the first installation of the FRITZ!Box for a new DSL/VDSL line.

Additional improvements to the DSL software provide for improved stability and faster transmission over various connections. The DSL diagnostics data have also been expanded for error analysis, so that future optimizations can be analyzed in even greater detail.
