Fritzbox 7590 (AX), 7530 or 6660? The right Fritzbox for every connection

Share your love

Long awaited, finally available: The Fritzbox 7530 AX (test report) and Fritzbox 7590 AX (test report) are the first VDSL routers from AVM with the new WiFi standard WiFi-6 (11ax). The Fritzbox Cable 6660 (test report) for the cable internet and the 5530 Fiber for the fiber optic connection also work with WiFi-6. The WLAN speed is an important criterion when deciding on a Fritzbox. But the router, as a home network and telephone switchboard, should simply connect all devices and bring them to the Internet. Therefore, features such as telephone, USB and LAN connections as well as the capabilities of the built-in modem are also important.

After we have already presented all current Fritz WLAN repeaters, in this article we will examine in detail the differences between the models for VDSL, cable, fiber optics and LTE and recommend the right Fritzbox for each network. The article appears as part of our Fritzbox theme world.

The Fritzbox 7590 AX (test report) is the current top model for the VDSL connection. Your modem supports profile 35b for supervectoring (up to 300 Mbit / s download), the WLAN works with WiFi-6 modules and Multi-MIMO. The Fritbox 7590 (test report) is almost identical, but still with WiFi-5. Both score points with the telephone connections. They each support one ISDN device, two analog devices via RJ11 or TAE and up to six cordless telephones via DECT.

The Fritzbox 7580/7583 differs from the 7590, especially in terms of the housing design, because it stands upright. Otherwise it offers the same equipment, but its modem is only suitable for vectoring connections up to 100 Mbit / s. More on this in our guide Fritzbox 7490, 7580 and 7590 in comparison. Too bad: none of the current VDSL2 Fritzboxes has a LAN port with 2.5 GBit / s or more, that is reserved for the Fritzbox 6660 Cable and the fiber optic modem Fritzbox 5530 Fiber.

At 169 euros, the new Fritzbox 7530 AX is slightly cheaper than the 7590, but has fewer connections: It lacks an additional WAN port, for example, to connect it to an upstream modem for an Internet connection via cable or fiber optics. One of the four Gigabit LAN ports must be used for this. In addition, it has no socket for an ISDN telephone and only a connection option for analog telephone devices.

Its plus point is the future-proof WLAN standard: The advantages of WiFi-6 are particularly noticeable when several end devices that also support WiFi-6 are transmitting in the network. The new WPA3 encryption supports the Fritzbox 7530 AX, of course – but also all Fritzboxes with 11AC WLAN on which at least Fritz OS 7.20 is installed. This also applies to the Fritzbox 7530, which, apart from WLAN, is equipped like the 7530 AX: Your wireless network works with the 11AC standard and a maximum of two parallel data streams. It is therefore recommended for smaller WLANs and if a quick switch to WiFi-6 is not planned.

Anyone who uses the Fritzbox 7490 introduced in 2013 does not necessarily have to switch to a more up-to-date model. Because AVM regularly provides the veterans with the latest updates and new functions. But the router is no longer recommended for new purchases, especially since it is usually more expensive than the better-equipped Fritzbox 7590.

Technically speaking, there is little to be said for the Fritzbox 7430, which only offers 11n WLAN in single-band operation with 2.4 GHz and a maximum of 450 Mbit / s and only Fast Ethernet for the LAN ports. It is usually cheap to get, so it can be used in conjunction with a faster Fritzbox on the Internet connection as a cheap mesh repeater to expand the WLAN and serve as an additional DECT base.

The equipment of the Fritzbox 3490 is the same for Internet (VDSL vectoring up to 100 Mbit / s) and WLAN speed (11AC over 5 GHz with 1733 Mbit / s and 11n over 2.4 GHz with 450 Mbit / s) and the connections ( 4x Gigabit LAN and 2x USB 3.0) of the Fritzbox 7490. But it lacks the connections for ISDN and analog telephones and the DECT function. Anyone who calls via VoIP telephone via the LAN socket or via smartphone via WLAN can access it.

As with the Fritz boxes for VDSL, the same applies to the models for the cable connection: The latest Fritz box does not offer the best equipment. The support for WiFi-6 speaks in favor of the Fritzbox 6660 Cable (test report), especially since, in contrast to the Fritzbox 7530 AX, it already serves 160 MHz radio channels over 5 GHz and can therefore achieve up to 2400 Mbit / s over 5 GHz under optimal conditions . The 6660 Cable has a 2.5 Gbit connection in addition to the four Gigabit LAN ports so that this speed also reaches devices connected via LAN, such as a NAS.

The Fritzbox 6591 Cable is better suited for telephony, but it is also significantly more expensive: It has an additional connection for analog telephones and a socket for an ISDN telephone. It lacks the 2.5 Gbit LAN port as well as WiFi-6. But for 11AC it offers the maximum speed of 1733 Mbit / s and up to 800 Mbit / s over 11n and 2.4 GHz.

Both cable Fritzboxes are future-proof, because their modem supports the Docsis 3.1 standard, which allows Internet connections with 1 GBit / s and more. At Vodafone, for example, this standard is used for all connections from 500 Mbit / s, the provider is increasingly upgrading its infrastructure to it. This is why Fritzbox models for Docsis 3.0 such as the 6590 Cable, 6490 Cable or 6430 Cable are no longer recommended.

The Fritzbox 6890 LTE goes online via its Cat.6 modem with up to 300 Mbit / s. But the router can also access the Internet via VDSL via its supervectoring-capable modem. A gigabit WAN port can also be used to connect to an existing cable or fiber optic modem, so that the expensive router can be used with all types of connection. A separate tariff is required for each access, because the Fritzbox is not suitable for Telekom’s LTE-DSL hybrid offer. In terms of WLAN and telephony, their equipment largely corresponds to the VDSL and cable top models 7590 and 6591, and an ISDN connection is also on board.

The equipment of the Fritzbox 6850 corresponds to the VDSL Fritzbox 7530, so it offers, among other things, 11AC WLAN with two parallel data streams and MU-MIMO, a connection for analog telephones in addition to the DECT function and a USB 3.0 port. It is exciting that with the Fritzbox 6850 5G there is already a model that not only supports LTE but also the even faster 5G radio standard. Up to 1.3 Gbit / s in the download and 600 Mbit / s in the upload are possible. Otherwise the router to the Fritzbox 6850 is identical.

The Fritzbox 6820 LTE is even cheaper: It does without the telephone functions and a USB connection. When it comes to WLAN, it only offers 11n with up to 450 Mbit / s. The LTE modem of the 6850 and 6820 provides a maximum of 150 Mbit / s for Internet access in accordance with Cat.4. You can safely ignore the Fritzbox 6810, it is from 2012, has outdated technology and is significantly more expensive than the more recent models.

When it comes to LTE Fritzboxes, you should look carefully: AVM is bringing new versions onto the market without notice, which differ primarily through the built-in LTE modem. The current version is about 2 for the Fritzbox 6890 LTE and version 3 for the Fritzbox LTE 6820 – the version number is on the nameplate on the underside of the housing. An improved LTE modem provides a faster or more stable connection as it supports additional LTE bands and advanced carrier aggregation. However, a new version can also mean that the Fritzbox can no longer be used with tariffs from certain providers, although the model is on their compatibility list.

Fritz boxes for these types of connection can hardly be found in free trade. The provider usually offers them for free or for rent at the appropriate tariff. The fiber optic models Fritzbox 5491 and 5490 are equipped like the Fritzbox 7490. The 5491 fits the GPON connection variant that Telekom uses for its fiber optic tariffs. The 5490 is suitable for providers whose fiber optic networks are based on AON.

The only fiber optic Fritzbox on the market is the Fritzbox 5530 Fiber. It is similar to the Fritzbox 7530, but offers an SFP connection for G-PON, XG-PON, XGS-PON and AON as well as a fast 2.5 Gbit / s LAN connection. It also supports WiFi-6, but for some inexplicable reason AVM has omitted the addition of “AX” to its name. That confuses. With the telephones, an analog device and up to six DECT telephones can be connected directly to the router.

The Fritzbox 7583 masters VDSL with bonding: bundling two connections doubles the data rate, but the provider must support this. In addition, the 7583 understands the standard: Some local providers in Germany use this for home networking via copper cables if the building is connected via fiber-optic (FTTB, fiber-to-the-building). In the individual apartments, a bandwidth of 1 GBit / s or more is possible via telephone cable.

The cheapest Fritzbox models 4040 and 4020 are used behind the provider modem, to which they are connected via a LAN cable via the WAN port. The 4040 brings the devices in the home network online via 11AC WLAN with two parallel data streams and four gigabit ports. The 4020 model only transmits via 11n WLAN with a maximum of 450 Mbit / s, its LAN ports only support Fast Ethernet speeds. Telephone connections and DECT capability are both missing.

AVM offers a suitable Fritzbox for every type of connection. Choosing the right model depends on how many devices in the home network the router connects online and which telephone connections it should have. The top models 7590 for VDSL, 6591 Cable for cable connection and 6890 LTE for Internet via cellular network leave nothing to be desired.

The Fritzbox 7590 AX, 7530 AX, 5530 and 6660 Cable already come with future-proof WiFi-6, but they sometimes lack the ISDN connection and another option for analog devices. For smaller home networks that do not require top speed for WLAN, the cheaper Fritzbox 7530 variants for VDSL and 6850 LTE are suitable.
