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 "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 factory 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 factory settings. This box is to become the Mesh Repeater.
- Connect the LAN 1 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 is operating 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.
If you've received the second FRITZ!Box from your internet provider this feature may not work in some cases. Please configurate this FRITZ!Box as a mesh repeater by visit the FRITZ!Box GUI manually. Instructions for configuring a FRITZ!Box connected via wireless LAN as a Mesh Repeater are presented at en.avm.de/mesh-faq
New and improved Features in FRITZ!OS 6.83
- NEW: Option for loading the previous LTE modem software
- NEW: New software version for the LTE modem
- NEW: TR069 query parameters supported for LTE connection
- NEW: Text reception supported -- texts received output as event
- 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
- NEW: IP address (DHCP) can be changed directly in the device details
- NEW: FRITZ!Hotspot - the wireless guest access with additional functions for cafés, shops or practices: Captive portal with own logo, text and link to own homepage. Details at https://en.avm.de/guide/practical-wifi-features/the-fritzhotspot-for-your-guests/
- NEW: New convenience features added to myfritz.box user interface and optimized display on smartphones and tablets (responsive design)
- NEW: Certain settings and features require additional confirmation by the user where the FRITZ!Box is located
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.
Even better and easier: MyFRITZ! for browser and app Following the fritz.box user interface - the window to the FRITZ!Box - with FRITZ!OS 6.83 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 their FRITZ!Box - 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 and the changing of certain settings are 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 6.83 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 6.83 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.
