The short answer
A router label such as AX3000 or BE9300 squeezes two facts into one code. The letters tell you the Wi-Fi generation: AX is Wi-Fi 6 (the technical standard 802.11ax), AXE is Wi-Fi 6E, and BE is Wi-Fi 7 (802.11be). The number is the maximum rates of all the router's radio bands added together and rounded, in megabits per second (Mbps; our guide to broadband speed units explains Mbps, MB/s and Gbps).
Don't expect one phone, laptop or TV to get near that number. Most devices connect on one band at a time, so they are only ever offered that band's share; using more than one band at once needs Wi-Fi 7 on both ends. The device's own Wi-Fi hardware sets limits too. The figure is a theoretical signal rate worked out from the Wi-Fi standards, not a measured speed, as the makers' own footnotes say. Then your broadband line and the router's ports put a lid on what reaches the internet.
So treat the number as a rough class marker; the useful detail is further down the spec sheet.
What the letters mean: AX, AXE and BE
The letters come from the IEEE 802.11 standards that Wi-Fi is built on. NETGEAR describes Wi-Fi 6 as the generational name for 802.11ax, also known as AX Wi-Fi, so you may see Wi-Fi 6 routers sold simply as "AX routers".
Letters on the box | Standard | Generation | Bands | Example from a maker's own page |
|---|---|---|---|---|
AX | 802.11ax | Wi-Fi 6 | 2.4GHz and 5GHz (6GHz models are sold as 6E) | NETGEAR RAX20 (AX1800), ASUS RT-AX5400 (AX5400), TP-Link Deco X50-Outdoor (AX3000) |
AXE | 802.11ax, plus the 6GHz band | Wi-Fi 6E | 2.4GHz, 5GHz and 6GHz | TP-Link Archer AXE75 (AXE5400) |
BE | 802.11be | Wi-Fi 7 | Up to three: 2.4GHz, 5GHz and 6GHz | TP-Link Archer BE550 (BE9300) |
NETGEAR describes Wi-Fi 6E as an extension of Wi-Fi 6 that introduces a new 6GHz band, and plain Wi-Fi 6 as using the 2.4GHz and 5GHz bands. The Wi-Fi Alliance, the industry body, counts 6GHz as part of Wi-Fi 6, but kit that has it is sold as Wi-Fi 6E, like TP-Link's Archer AXE75. Wi-Fi 7 can work across all three bands, but a router sold as Wi-Fi 7 does not have to include 6GHz, as the provider examples further down show.
One caveat: these labels are a makers' convention. We found no official definition of how the number is worked out, so what follows is based on how TP-Link, ASUS and NETGEAR break down their own figures. For what each generation actually changes, see our guide to Wi-Fi 6, 6E and 7.
How the number is built
Each band on a router has its own maximum rate. Add the bands together, round to a tidy figure and you get the number on the box. Here are five routers, using the per-band rates on each maker's own spec page (checked October 2026). The final column is our own arithmetic.
Router | Label | 2.4GHz | 5GHz | 6GHz | Bands add up to |
|---|---|---|---|---|---|
NETGEAR RAX20 | AX1800 | 600Mbps | 1,200Mbps | None | 1,800Mbps |
TP-Link Deco X50-Outdoor | AX3000 | 574Mbps | 2,402Mbps | None | 2,976Mbps |
ASUS RT-AX5400 | AX5400 | 574Mbps | 4,804Mbps | None | 5,378Mbps |
TP-Link Archer AXE75 | AXE5400 | 574Mbps | 2,402Mbps | 2,402Mbps | 5,378Mbps |
TP-Link Archer BE550 | BE9300 | 688Mbps | 2,880Mbps | 5,760Mbps | 9,328Mbps |
ASUS even prints the sum on its spec page, listing the RT-AX5400 as "574+4804 Mbps", and NETGEAR rates the RAX20 at "up to 600+1200Mbps". A dual-band router has two numbers to add; a tri-band router has three.
Same number, very different routers
Because the label is a total, it hides how the total is shared out. The ASUS RT-AX5400 and TP-Link's Archer AXE75 both add up to 5,378Mbps and both round to 5400. But ASUS puts 4,804Mbps on a single 5GHz band, while the AXE75 splits 4,804Mbps between a 5GHz band and a 6GHz band at 2,402Mbps each.
Don't read the bigger 5GHz figure as a promise. ASUS lists 20/40/80/160MHz channel widths and four external antennas for the RT-AX5400; the 4,804Mbps figure is the band's maximum with every feature the router supports, so a device with fewer streams or narrower channels cannot use all of it.
The AXE75's split matters differently. A device that supports 6GHz gets a separate band which, TP-Link says, has no overlap or interference from other bands and older devices. A device without 6GHz only sees the other two, so the 6GHz band's 2,402Mbps share of the label is out of its reach. Read the per-band line alongside what your devices support.
Streams in the product name
Some makers add a stream count. NETGEAR calls the RAX20 a "4-Stream AX1800" router, and TP-Link describes the BE550 as "6-Stream Tri-Band". That is one figure for the whole router; it doesn't say how the streams are split between bands. Spec sheets that list streams per band, as MIMO figures (multiple-input, multiple-output) such as 2x2 or 4x4, tell you more: Rebel Internet lists its Heights HT-178AX as AX5400 with 4x4 on 5GHz and 2x2 on 2.4GHz.
Nor are a router's streams all aimed at one device. The Wi-Fi Alliance lists multi-user MIMO among Wi-Fi 6's key features, saying it lets a router transfer more data at one time and handle more devices at once.
"Up to" means a signal rate, not a test result
Every maker we checked footnotes these figures. TP-Link says its maximum wireless signal rates are the physical rates derived from the IEEE 802.11 specifications, that actual throughput, coverage and the number of connected devices are not guaranteed, and that building materials, obstacles, traffic and where the device sits all change the result. NETGEAR says throughput can be lowered by network traffic and building construction, and ASUS that it varies with network and environmental conditions.
So the number is a theoretical maximum under the standard, not a speed measured in a house. Coverage is a separate spec line: TP-Link gives the BE550's range as a house size.
Why one device gets far less than the number on the box
Five separate limits stand between the label and what a phone or laptop gets. Any one of them can keep a device well below the figure on the box.
1. A device uses one band, or a few with Wi-Fi 7
Multi-link operation (MLO), the feature that lets a device use more than one band at the same time, arrived with Wi-Fi 7: the Wi-Fi Alliance lists it among Wi-Fi 7's features, not Wi-Fi 6's. So a Wi-Fi 6 or 6E device connects on one band at a time.
Even with Wi-Fi 7, only a device that supports MLO can use more than one band at once, and TP-Link says a device needs both MLO and 6GHz support to reach the BE550's full figure, "up to 9.3 Gbps", across all three bands.
A single-band comparison is often the more realistic one. Intel gives a maximum speed of 5.8Gbps for its Wi-Fi 7 BE200 adapter, and only with a 320MHz channel and 4096-QAM; TP-Link notes that 320MHz channels exist only in the 6GHz band. By our arithmetic, that is close to the BE550's 6GHz band on its own (5,760Mbps), not the 9,300 on the box.
2. Your device's own Wi-Fi hardware sets a limit
Devices have stream counts too. Apple lists the iPhone 16 as Wi-Fi 7 (802.11be) with 2x2 MIMO, and Intel's BE200 adapter is also 2x2.
Router bands vary. EE's Smart Hub 7 Pro is 4x4 on each of its three bands, and Airband's Nokia Beacon G6 is 4x4 on its 2.4GHz and 5GHz bands, while the 2.4GHz bands on EE's Smart Hub 7 Plus and Rebel's HT-178AX are 2x2. TP-Link lists the number of antennas and the hardware of both the router and the device's Wi-Fi adapter among the things that set wireless link speed. So compare your device's stream figure with the band it will use, not with the total on the box.
3. Both ends need the same features
The headline assumes the device supports everything the router does. NETGEAR's footnote says the RAX20's "up to 1800Mbps" wireless speed is achieved when connecting to other 802.11ax 1800Mbps devices. TP-Link says Wi-Fi 6 and 6E features such as 1024-QAM and 160MHz channels need the device to support them too, and that Wi-Fi 7's MLO, 320MHz channels and 4K-QAM (4096-QAM, a denser way of packing data into the signal) need supporting devices as well.
TP-Link also notes that 320MHz channels exist only on the 6GHz band and may be restricted by regulation in some regions, so a Wi-Fi 7 router or device without 6GHz cannot use them.
4. Distance, walls and interference lower the link
Your device and the router agree a link speed between them, and it moves around. TP-Link says different devices negotiate different link speeds with the router depending on the wireless mode, the distance and the noise level, meaning interference from other wireless transmissions. Its own help page shows a device with a link speed of 325Mbps on a router whose maximum on 5GHz is 1,300Mbps.
If speeds fall away in certain rooms, a bigger number on a new router is not the obvious fix: the rating says nothing about reach. Our guide to mesh Wi-Fi versus Wi-Fi extenders covers getting signal into far rooms, and if one phone or laptop lags behind everything else, why one device is slower than the rest shows how to check the link speed it has actually agreed.
5. Link speed is not your broadband speed
TP-Link describes the signal rate as the maximum wireless link speed between the router and a device, and says it is not the internet speed delivered by your provider. Internet speed is limited by the slowest point in the path, including your broadband connection, the router's WAN port (the socket the internet arrives through) and the cables or adapters used. TP-Link gives the example that a router with a 100Mbps WAN port cannot deliver more than 100Mbps of internet speed, whatever its wireless signal rate.
The same logic applies at the top end. The BE550 has a 2.5Gbps WAN port, so however much its bands add up to, traffic to and from the internet passes through a 2.5Gbps socket. To see where your own limit sits, run our broadband speed test on a computer cabled to the router first, to see what the line gives, then over Wi-Fi to see what your Wi-Fi gives. If your plan is faster than 1Gbps, our guide to a multi-gigabit home network walks through the ports and cables that matter.
Reading your provider's hub specification
If you take the router your provider sends, its spec is part of the deal. Some providers quote an AX or BE label; others list bands and streams. This is what a selection showed in October 2026; routers change, so check the page for the exact package you order.
Provider and router | AX/BE label quoted? | What the provider lists |
|---|---|---|
EE Smart Hub 7 Pro | No AX/BE number or combined figure | Wi-Fi 7, tri-band, 4x4 on 2.4GHz, 5GHz and 6GHz; 4 x 2.5GigE LAN, 1 x 2.5GigE WAN |
EE Smart Hub 7 Plus | No | Wi-Fi 7, dual-band: 2.4GHz 2x2, 5GHz 4x4; 1 x 2.5Gbps LAN, 3 x 1Gbps LAN, 1 x 2.5Gbps WAN |
Trooli Nokia Beacon 19.1 | BE19000 | Wi-Fi 7, tri-band (2.4GHz, 5GHz and 6GHz), 10Gbps WAN port. Nokia's own page adds 4x4 MIMO on each band, MLO, one 10Gbps and two 1Gbps LAN ports. Trooli says a Wi-Fi 7 Beacon comes with selected packages, and it also offers the Beacon 9 (up to 9.4Gbps of Wi-Fi capacity) |
Airband Nokia Beacon G6 | AX6000 | 4x4 on 2.4GHz and 5GHz, 160MHz channels |
Rebel Internet Heights HT-178AX | AX5400 | Wi-Fi 6, dual-band: 5GHz 4x4, 2.4GHz 2x2 |
toob Wi-Fi 7 router | Not on the pages we checked | Wi-Fi 7 for new customers, listed with each home package; dual-band 2.4GHz and 5GHz. toob says many existing customers have its Wi-Fi 6 router |
Ogi eero routers | Not on the page we checked | eero 6 with Ogi 150 and 300; eero 7 with Ogi 1Gig |
EE gives no headline figure but lists bands and streams, so you can see the Smart Hub 7 Plus has no 6GHz band and only a 2x2 2.4GHz band. Nokia's Beacon 19.1 page lists a "PHY rate of BE19000" alongside "Wi-Fi capacity of up to 19 Gbps". Trooli's pages (checked October 2026) don't say which packages get the Beacon 19 rather than the Beacon 9, so check the router listed for yours. On a fast full-fibre plan, the 10Gbps WAN port is the detail that decides what the internet connection can carry.
toob's router shows why the generation alone is not enough. It is Wi-Fi 7 but dual-band, so it has no 6GHz band and therefore none of the 320MHz channels that only exist there. It also shows the router can depend on when you joined. Add-on kit can differ again: Trooli says its optional Wi-Fi Plus boosters use Wi-Fi 6, although its Beacon routers are Wi-Fi 7. See EE broadband deals, Trooli broadband deals, toob broadband deals or Ogi broadband deals for current packages, and if you are joining Ogi, what happens at an Ogi installation covers the eero kit Ogi supplies.
A spec-sheet checklist
For a provider's hub or a router in a shop, run down these lines rather than stopping at the label:
- Generation. AX, AXE or BE; Wi-Fi 6, 6E or 7; or 802.11ax and 802.11be.
- Bands. Is 6GHz named? "Tri-band" alone does not always say which three.
- MLO. On a Wi-Fi 7 router, is multi-link operation listed? It is what lets a Wi-Fi 7 device use more than one band at once.
- Rate per band. The largest single-band figure is a better guide to what one device on that band could be offered than the total.
- Streams per band. Compare them with your own devices. A phone listed as 2x2 uses two streams.
- Channel widths. Wi-Fi 6 spec sheets list up to 160MHz (ASUS gives 20/40/80/160MHz for the RT-AX5400). Wi-Fi 7's 320MHz channels exist only in the 6GHz band and need support on both ends.
- WAN and LAN port speeds. These cap what your broadband can deliver through the router, whatever the Wi-Fi rating.
- The footnote. It tells you the figure is a theoretical signal rate and what conditions it assumes.
Does a bigger number matter for your home?
A bigger label means a bigger combined maximum, often with newer features your devices may not support. Whether that helps depends on your devices, plan and home. These are general examples, not personal advice:
Example situation | What the label does and doesn't tell you |
|---|---|
Mostly older Wi-Fi 5 laptops, tablets and TVs | A higher AX or BE number won't make those devices use features they lack; the per-band figures they can use, and coverage, matter more |
Recent Wi-Fi 7 phones listed as 2x2 | Whether the router has a 6GHz band and supports MLO matters more than the size of the total |
Broadband plan of 1Gbps or less | The line and the router's ports set the ceiling; a big Wi-Fi rating won't raise it, though one device's Wi-Fi link can still fall below the plan |
Plan faster than 1Gbps | Check the WAN and LAN port speeds first; a large BE number with a 1Gbps port will still cap the connection there |
Weak signal in far rooms | The rating says nothing about range; look at mesh, extra access points or a cable |
If your provider's router is a generation or two behind your devices, ask about an upgrade before buying your own; asking your provider for a newer router explains how to raise it. If you do replace a router, reusing an old router as an access point explains when an old one can add Wi-Fi to far rooms, and which provider hubs have to go back instead. And if your phone can't see a new router's 6GHz network at all, Wi-Fi network not showing up covers band and channel checks.
The router can change with the plan, so note which hub comes with each package on the provider's page, then compare broadband deals at your postcode. Fibre broadband deals covers full-fibre packages, and the broadband providers list links to each provider. The deal listings come from a partner's comparison tool, and you order with the provider itself; we don't switch you.
Questions to ask a provider about its router
A deal listing may name only the Wi-Fi generation, so before you order, ask:
- What are the Wi-Fi rates and stream counts for each band on the router that comes with this package?
- Does it have a 6GHz band, and does it support multi-link operation?
- Which channel widths does it support on each band, such as 160MHz or 320MHz?
- If I'm an existing customer re-contracting, will I get this router or keep my current one?
- If I add mesh units or a booster, which Wi-Fi generation are they?
Keep the answers in writing if you can. For how speed claims in broadband adverts are regulated, see our guide to broadband advert rules.
Router speed label FAQs
What does AX3000 mean on a router?
AX means the router uses Wi-Fi 6 (the 802.11ax standard). 3000 is the maximum rates of its bands added together and rounded. TP-Link's AX3000 Deco X50-Outdoor, for example, is rated at 574Mbps on 2.4GHz plus 2,402Mbps on 5GHz. It is a theoretical signal rate, and a Wi-Fi 6 device connects on one band at a time (using several bands together arrived with Wi-Fi 7), so no single device is offered the full 3000.
What does BE mean on a Wi-Fi router?
BE marks a Wi-Fi 7 router, built on the 802.11be standard. The number after it is the bands' maximum rates added together: TP-Link's BE9300 Archer BE550 is rated at 5,760Mbps on 6GHz, 2,880Mbps on 5GHz and 688Mbps on 2.4GHz. Not every Wi-Fi 7 router has a 6GHz band, so check the bands too.
What is the difference between AX and AXE routers?
Both use the 802.11ax standard. AX is Wi-Fi 6, which on router boxes means the 2.4GHz and 5GHz bands. AXE is used for Wi-Fi 6E routers, which add a 6GHz band; TP-Link's Archer AXE75, for example, is an AXE5400 tri-band router. Your device needs Wi-Fi 6E or Wi-Fi 7 with 6GHz support to use that extra band.
Why is my Wi-Fi speed lower than the number on the router box?
The box figure adds every band together, while your device usually connects on one. Your device's own Wi-Fi hardware sets limits (the iPhone 16, for example, is listed as 2x2), both ends need matching features, and distance, walls and interference lower the link. Router makers say in their footnotes that the figure is a theoretical signal rate and that real throughput is not guaranteed.
Does my phone use all of a router's bands at once?
Usually not. Multi-link operation, which lets a device use more than one band at once, is a Wi-Fi 7 feature, so a Wi-Fi 6 or 6E phone connects on one band at a time. A Wi-Fi 7 phone can use several bands together only if it and the router both support multi-link operation, and TP-Link says a device also needs 6GHz support to reach its BE9300 router's full figure across all three bands.
Is the router's AX or BE number my broadband speed?
No. TP-Link says the signal rate is the wireless link speed between the router and a device, not the internet speed your provider delivers. Your broadband plan, the router's WAN port (where the internet arrives) and any cables or Ethernet ports in the path set the limit on internet speed, however big the Wi-Fi rating is. Test wired, then over Wi-Fi, to see which one is holding you back.
