####New features for Mesh

General information on Mesh is presented at en.avm.de/mesh-networking.


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 "fritz.box -> 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 en.avm.de/mesh-faq.


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

Requirements:

  • 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 en.avm.de/mesh-faq


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. Caf\E9s, 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. Caf\E9s 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.


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 letsencrypt.org. 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 letsencrypt.org.

Proceed as follows:

  1. First you need to register your FRITZ!Box with MyFRITZ! (myfritz.net).
  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 https://myfritz.net.

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, "fritz.box" 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.


New and improved Features in FRITZ!OS 6.80

Internet: NEW - Display of Internet use by guests in the Online Monitor New - Guaranteed data rate for home network devices despite intensive use of the guest network NEW - Option for autonomous port sharing (UPnP/PCP) can be enabled for each device

Home network: NEW - IP address (DHCP) can be changed directly in the device details

Wireless LAN: NEW - To improve data transmission, a dual-band wireless device can be set to switch between the 2.4 and the 5-GHz frequency band automatically (band steering)

MyFRITZ!: NEW - New convenience features added to myfritz.box user interface and optimized display on smartphones and tablets (responsive design)

Security: 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 - Certain settings and features require additional confirmation by the user where the FRITZ!Box is located

Storage (NAS): NEW - FRITZNAS user interface optimized for tablets and smartphones (responsive design)

USB/UMTS: 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.

Even better and easier: MyFRITZ! for browser and app Following the fritz.box user interface \E2?? the window to the FRITZ!Box \E2?? with FRITZ!OS 6.80 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 saved data 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 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. 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.

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.

Additional improvements in FRITZ!OS 6.83:

DSL: Improved - Optimization for VDSL vectoring Improved - Better interoperability with various VDSL and ADSL connections Improved - Compatibility mode added for VDSL connections with supervectoring (35B)

Internet: Improved - Display of online time in the parental controls overview Improved - Labeling of time axes in the Online Monitor Improved - Filters for websites take account of blocked domains for https calls as well Improved - Support for pure IPv6 devices in parental controls Improved - Port sharing combined with MyFRITZ! sharing and IPv6 sharing Improved - Complete firewall exceptions possible for downstream routers with IPv6 Improved - Static routes can be defined for IPv6 Bug fix - Shifted time scale in the graphic overview of permitted online time on fritz.box/surf.lua

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.

Now there is an option for granting guest access to the wireless LAN or LAN only after consent to the FRITZ!Box owner's terms of use. The guest is taken first to a captive portal to signal consent. Without confirming this page, you cannot connect to the Internet.

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. The firewall can be operated in stealth mode to prevent ping queries. TLS security has been improved and port 25 received a new filter to block the unsecured e-mail dispatch.
