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.
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.
- 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.

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
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:
- First you need to register your FRITZ!Box with MyFRITZ! (myfritz.net).
- Under "Internet / MyFRITZ! Account", enable the "Let's encrypt" optLet's Encryption.
- 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.
Instructions for installing the update:
Use the update function offered in the user interface to install the update. This automatically offers you the right FRITZ!OS. Click "Wizards", select "Update" and then follow the instructions on the screen.
