FRITZ!Box 7530 AX, Wi-Fi 6 DSL router with telephony review
The only router here with a modem and a telephone exchange inside it, and the only one whose headline figure is exactly the sum of the two rates printed beneath it.
It is a European model with no Amazon.com offer on October 26, 2026. It is sold on the European Amazon stores, often with a European plug or power adapter, and a US buyer would be relying on an importer.
Models on this shelf that Amazon.com did sell on that date:
A Wi-Fi 6 DSL router with up to 1800 Mbit/s at 5 GHz and 600 Mbit/s at 2.4 GHz at the same time; internet speeds up to 300 Mbit/s through VDSL supervectoring 35b, with mesh joining the maker other products into one network; a VoIP exchange with up to five answering machines and a fax function, and a DECT base for up to six cordless handsets and for switched sockets and radiator controls; a media server over USB and network storage feeding films, photographs and music to tablets, televisions and hi-fi; and a box containing the router, a mains adapter, a four-meter DSL cable, a 1.5 m (5 ft) network cable and an instruction leaflet.
The arithmetic that closes
1800 plus 600 is 2400. The title says up to 2.4 Gbit/s. Nothing has been rounded, and the parts and the sum are on the same page. Two listings in this whole lot manage that, and both come from this maker.
Two ceilings in adjacent bullets
The radios are quoted at 2.4 Gbit/s. The line into the building is quoted at 300 Mbit/s. Both numbers are true and they answer different questions: the first is about moving a file between two devices in the house, the second is about everything arriving from outside.
The sockets that are implied
A 1.5 m (5 ft) network cable is in the box, so there is at least one socket to plug it into. A media server runs over USB, so there is at least one USB socket. Neither is counted, neither is rated, and neither generation is given.
Before ordering
Check the line first. On fiber the modem, the DSL cable and the supervectoring bullet are all inert, and what is left is a Wi-Fi 6 router with an unpublished socket count.
Where it holds up, and where it stops
Strengths
The headline figure is exactly the sum of the two published band rates, with no rounding in the maker favor
Carries the modem inside, so a DSL line needs nothing in front of it, and the four-meter DSL cable is listed in the box
States a full telephone exchange: VoIP with up to five answering machines, fax, and a DECT base for up to six handsets and for the maker’s own switched sockets and radiator controls
Compromises
Not one Ethernet socket is counted or rated, although a network cable is listed in the box
The USB socket is implied by a media server function and never counted or given a generation
The DSL ceiling of 300 Mbit/s is far below the 2.4 Gbit/s the radios are quoted at, and the two figures sit in adjacent bullets without comment
Specifications
Wi-Fi generation
Wi-Fi 6 — stated in the title and written WLAN AX in the first bullet
IEEE designation
Not published on the listing — the generation appears as Wi-Fi 6 and as WLAN AX, and no 802.11 letter pair is printed in the five bullets
Stated class figure
Up to 2.4 Gbit/s — stated in the title without an AX prefix, and it is exactly the sum of the two published band figures: up to 1800 Mbit/s at 5 GHz and up to 600 Mbit/s at 2.4 GHz, used at the same time
Band count
Two, each with a rate and stated as simultaneous — 5 GHz up to 1800 Mbit/s and 2.4 GHz up to 600 Mbit/s
Stream count
Not published on the listing — no stream figure appears for either radio anywhere in the title or the bullets
WAN port speed
Not published on the listing as an Ethernet figure — the incoming line is DSL, with VDSL supervectoring 35b stated at up to 300 Mbit/s, and a four-meter DSL cable is listed in the box
LAN port speed
Not published on the listing — a 1.5 m (5 ft) network cable is listed among the box contents and no socket is counted or rated
Port count
Not published on the listing — the five bullets cover the radios, the DSL line and mesh, the telephony, the media server and the box contents, and none counts a socket
USB ports
Not published on the listing as a count — a media server over USB and network storage is stated, so a socket exists, and neither its number nor its generation is given
Antenna arrangement
Not published on the listing — no antenna is counted or described, and the unit is not stated to have external ones

The questions that come up before an order
Why is the DSL figure so much lower than the Wi-Fi figure?
They describe different things. The 300 Mbit/s is what the copper line into the building can carry under VDSL supervectoring 35b; the 2.4 Gbit/s is the sum of the theoretical peaks of the two radios inside. Traffic from the internet is limited by the first figure; traffic between devices in the house is not.
What does a DECT base station in a router do?
It lets cordless handsets register directly to the router rather than to a separate base, and on this listing it also serves the maker’s own switched mains sockets and radiator valves. It is the reason a router of this kind replaces two or three boxes.
Our score
8.4/ 10
A telephone exchange, a modem and a Wi-Fi 6 router in one case, with the radio arithmetic stated honestly and the wired sockets left uncounted. On a DSL line it is the most complete box here; on fiber, most of what it contains is unused.
The buyer this one serves, among network and storage gear
A household on a DSL line that wants the modem, the telephony and the radios in one box rather than three.

Wi-Fi 6 · 802.11ax named · AX3000 badge over 2976 Mbit/s published · two bands rated · AiMesh extendable · no socket published
One of two routers here to print an 802.11 designation, sold on the European Amazon stores, and one of several to leave every Ethernet socket uncounted.
Best for: A household with Wi-Fi 6 clients that intends to add a second mesh-capable unit from the same maker later.
Wi-Fi 6 · AX3000 = 2402 + 574 Mbit/s · 160 MHz and 1024-QAM · 1 WAN + 3 LAN Gigabit · WireGuard, OpenVPN, IPsec, PPTP and L2TP server and client
A Wi-Fi 6 router whose Amazon.com listing splits its AX3000 badge into two band rates, counts four Gigabit ports and names five VPN protocols, as server and client.
Best for: A household that wants a VPN server or client on the router itself and three wired devices, on a connection of up to a gigabit.
