Better WLAN for the Fritzbox: an overview of all Fritz repeaters

AVM supplies a whole range of extensions to its Fritzbox routers. In addition to more exotic things, such as outdoor sockets that can be switched via DECT, most customers are likely to be primarily interested in the repeater series. These devices extend the WLAN of the Fritzbox, provide better coverage and can close gaps in the wireless network. The great advantage of AVM is the mesh function. If desired, the repeaters can take over all the settings of the main router, i.e. things like WiFi name and password or the configuration for child safety. For the respective end devices, the mesh looks like a large network. This is useful for smart homes, for example, so that switches or sensors can reliably communicate with all other devices. AVM not only supplies individual WLAN routers, numerous devices have suitable modems for the respective Internet access. More on this in the article The best Fritzbox for VDSL, cables, LTE and fiber optics.

AVM currently has the following repeaters in its range:

  • The tri-band repeater 6000 (test report) transmits 1200 + 2400 + 2400 MBit / s gross, from three frequency blocks, from 3×4 = 12 antennas. If you add these individual values, then 6000 Mbit / s gross come together.
  • The tri-band repeater 3000 (test report) manages 400 + 866 + 1733 MBit / s gross. That is 2966 Mbit / s total performance, hence the value 3000 in the official name.
  • The dual-band repeater 2400 (test report) transmits 600 + 1733 = 2333 MBit / s gross. AVM then decided to round up to the Fritz Repeater 2400.
  • The dual-band repeater 1200 (test report) manages 400 + 866 = 1266 Mbit / s gross. AVM rounded it off and decided on the name Fritz Repeater 1200. That sounds exactly like half of the 2400.
  • The single-band repeater 600 (test report) transmits 600 Mbit / s gross in the 2.4 GHz band. The name Fritz Repeater 600 was probably the obvious choice.


To connect the access points to the router, you usually have two options: LAN or wireless. LAN should be preferred, as this is where the least amount of throughput is “lost”. AVM also calls this mode LAN bridge, the rest of the world usually calls it WLAN AP mode. The only exception: the small Fritz Repeater 600 does not have a LAN socket, so it cannot play a role in WLAN AP. Wherever possible, we recommend coupling the repeaters via LAN cable, as this clearly always gives the WLAN end devices the strongest and most stable throughput.

If you connect router and repeater via WLAN radio, they have to use part of their radio power for internal communication. That is the price for the luxury of a wireless connection for the purpose of replacing a LAN cable: This architecture takes a heavy toll:

  • The tri-band repeater 6000 usually sacrifices its highest frequency block in the 5 GHz II band, with a maximum of 2400 Mbit / s gross, for internal communication.
  • The tri-band repeater 3000 also mostly uses its highest frequency block in the 5 GHz II band for the internal connection, with a maximum of 1700 Mbit / s gross.
  • The dual-band repeater 2400 decides itself and dynamically how to use its 600 Mbit / s line at 2.4 GHz and / or its 1733 Mbit / s line at 5 GHz for the infrastructural connection with its WLAN router uses.
  • The dual-band repeater 1200 also dynamically decides how it uses its 400 Mbit / s line at 2.4 GHz and / or its 866 Mbit / s line at 5 GHz for the internal connection with its WLAN router.
  • The single-band repeater 600 only plays a single frequency block at 2.4 GHz with a total of 600 MHz gross. He has to use this narrow block at the same time for the infrastructural connection with his WLAN router and for the data transport to the WLAN end devices. This leaves little data throughput for the WLAN end devices.

Single-band repeaters, regardless of the WLAN manufacturer, must rightly put up with the criticism that they would receive (at least) half of their nominal gross performance on the way to the WLAN end device for the internal connection to their WLAN Lose router. Dual or tri-band repeaters have more options and higher throughput, but are more expensive.

But if the WLAN from the router becomes too weak just before the furthest room to email, surf or chat a bit, a single-band repeater for well under 50 euros can be a welcome solution for those last few meters.

The setup of the Fritz Repeater is simply explained and only requires three steps:

  1. Connect the Fritz Repeater to the mains and wait until the Connect LED flashes slowly.
  2. Briefly press the connect button
  3. Trigger the Connect or WPS function on the Fritzbox or on the router.

From many tests and installations we can confirm: The connection of a Fritz Repeater to a Fritzbox has actually worked as described for years. Regardless of whether the connection to the router was made via WLAN or via LAN cable.

This striking description of the coupling is missing on the packaging of the Repeater 1200 and 600, which is not half as large. The Repeater 1200 only says: “Convenient operation / Smart app”. The AVM 600 only says “Comfort & security / set up at the push of a button”. When pairing, these two small ones behave just like the larger repeaters 2400, 3000 and 6000.

With Wifi-6 not only does a higher speed come, but the WLAN can handle several devices at the same time. Since the number of WiFi-compatible devices continues to grow, you should keep an eye on the technology and think about it now when upgrading. The Fritz Repeater 6000 already adorns itself with the WLAN standard 802.11ax (Wifi-6). The other three still transmit 802.11ac, aka Wifi-5. The small Fritz Repeater 600 even ends with the ancient 802.11n, alias Wifi-4.

The new Fritz Repeater 1200 AX with WiFi-6 was announced on October 12, 2021. Two antennas each for the 2.4 and 5 GHz band should achieve a WLAN speed of up to 3,000 Mbit / s gross. Available from November 2021 at an RRP of 89 euros, a test will follow soon.

All five WLAN repeaters have a red WPS button clearly visible on the front. It has two main functions:

  • Router coupling: Pressing this Connect button starts the connection with a WLAN router, regardless of whether it is a Fritzbox or another router with WPS function.
  • Mobile device coupling: In addition, this red button can be used to simplify the connection to a WLAN device at the touch of a button, for example with a laptop or mobile phone. Then the WLAN security key is shot through to the end device and you don’t have to type it into your laptop or mobile phone yourself.

The large AVM 6000 has a 2.5 gigabit and a 1 gigabit Ethernet LAN port. This is the first AVM repeater with 2.5 GbE LAN. That’s a good thing, because its maximum, aggregated net WiFi performance is well above 1000 Mbit / s. This would be greatly slowed down when transitioning to the wired home network at a 1 GbE LAN port only.


The AVM 3000 has two 1 GbE LAN ports at the rear. The black power socket on the 3000 is not at the back, but at the bottom.

The 2400 and 1200 each have a 1 GbE LAN socket at the bottom. The LAN cables can hang down there. The AVM 600 is the only AVM repeater to have no LAN port at all. It can therefore not be connected to a WLAN router using a LAN cable.

If you connect a WLAN repeater with a WLAN router via LAN cable, then in case of doubt you can use the fastest LAN port on both sides. Example: The AVM 6000 has a 2.5 GbE LAN port. With a Fritzbox 6660 Cable (test report), or with the upcoming Fritzbox 4060, you would use its 2.5 port for the AVM 6000, unless these fast 2500 Mbit / s sockets are urgently needed for other purposes.

If the WLAN router only has 1000 Mbit / s LAN ports anyway, and not yet 2.5 GbE, then it doesn’t matter which of the usually four 1 Gbit / s ports you use for such a LAN bridge to the Repeater uses. You should just make sure that the LAN port used on the router is then set to 1000 Mbit / s mode, and does not use the back burner to communicate in 100 Mbit / s.


If you connect the repeater to the router via WLAN, there is a lot more to consider:

The ideal coupling takes place in the top 5 GHz WiFi block, provided that both partners, WiFi router and WiFi repeater, can even use a top block at all. Example: The AVM 6000 tri-band repeater can send and receive up to 2400 Mbit / s with up to 1000 mW in the 5 GHz II frequency block. This is the gray bar in the graph.

As the first Fritzbox ever, the upcoming 4060 can also transmit on three frequency blocks with 3×4 = 12 antennas. It is obvious that an AVM 6000 should optimally couple with an AVM 4060 that is equally powerful in terms of radio technology on this 5GHz II band with strong transmission. The 4060 is the first Fritzbox that can send and receive from three radio modules at the same time.

With restrictions, the principle can also be transferred to the Tri-Band Repeater 3000, whereby the internal communication there ends at 1733 Mbit / s.

Towards the right in the graphic, the compromises in the coupling between WLAN router and WLAN repeater are getting bigger and bigger. Nevertheless, these constructions also work, just not as fast as with an AVM 3000 or even with an AVM 6000.

With currently five (and from November 2021 even six) available WiFi mesh repeaters, AVM has a finely graded range: from the emergency solution for the furthest room, such as a Fritz Repeater 600, to the awesome AVM 6000, which is purely wireless in AP mode even high-end business models for over 1000 euros from Cisco, HP-Enterprise and Huawei Enterprise can compete

On a modern Fritzbox you can also combine several Fritz repeaters in LAN and WLAN bridge mode. In the private environment, WiFi mesh (theme world) is popular because it saves LAN cabling. Nevertheless, one should prefer the wired connection where possible. In any case, you should activate the mesh features of the Fritzbox so that there are no multiple radio cells with the same name, but a continuous WLAN.
