Updated June 2026. Buying a new router right now means choosing between Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 7 — three standards with very similar names and very different price tags. The gap between entry-level Wi-Fi 6 and a flagship Wi-Fi 7 router can be £400 or more. So which one do you actually need?
Short answer: Wi-Fi 6 is the right call for most homes and offices in 2026. It’s widely supported, affordable (routers from around £80), and fast enough for streaming, video calls, and online gaming. Wi-Fi 6E adds a 6 GHz band that cuts interference in dense environments — but only if your devices support 6E, which most don’t yet. Wi-Fi 7 delivers genuinely impressive speeds and lower latency, but it costs serious money and you’ll need new 2024+ devices to see any benefit.
I’ve been running a Wi-Fi 6E router (TP-Link Archer AXE75) at home for about 18 months alongside a colleague’s Wi-Fi 6 setup, and the real-world difference on a typical mix of phones, laptops, and smart home gadgets is smaller than the spec sheets suggest. Here’s what the numbers actually mean.
If you’ve already read our Wi-Fi 7 vs Wi-Fi 6 breakdown, this piece adds the 6E piece to the picture and gives you a practical decision guide.
What actually changed between Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 7?
Wi-Fi standards are certified by the Wi-Fi Alliance and built on IEEE 802.11 specs. Here’s what each generation actually introduced — in plain terms.
Wi-Fi 6 (802.11ax) — the current mainstream
Released in 2019 and now everywhere. Wi-Fi 6 brought two big improvements over Wi-Fi 5: OFDMA and improved MU-MIMO.
OFDMA (Orthogonal Frequency-Division Multiple Access) lets the router talk to multiple devices at the same time instead of one at a time. On a busy network — 15 phones, a few laptops, smart speakers — this matters a lot. MU-MIMO was expanded from 4 streams to 8, so the router can handle more simultaneous connections without slowing everyone down.
Theoretical max speed is 9.6 Gbps. In practice, on a 5 GHz channel with a decent device, you’ll see 500–800 Mbps at close range. Still more than enough for any internet connection available to most UK homes in 2026.
Wi-Fi 6E — the same engine, bigger road
Wi-Fi 6E is Wi-Fi 6, but with an added 6 GHz band. The UK opened up 480 MHz of 6 GHz spectrum in 2021 — that’s a lot of clean, uncongested airspace. In flat blocks, offices, or dense neighbourhoods where the 2.4 and 5 GHz bands are clogged with neighbours’ routers, 6 GHz makes a real difference.
The catch is range. 6 GHz signals don’t travel as far as 5 GHz, and they struggle with walls. In a two-storey house, you may not get 6 GHz coverage in the far bedroom. And again — your phone or laptop needs to support 6E to connect on that band. As of mid-2026, the Samsung Galaxy S23 series, iPhone 15 Pro, and some recent Android flagship chipsets (Qualcomm Snapdragon 8 Gen 2+) support 6E. Most budget and mid-range devices don’t.
Wi-Fi 7 (802.11be) — genuinely new tech
Wi-Fi 7 routers started hitting shelves properly in late 2023, with device support arriving through 2024. The theoretical ceiling is 46 Gbps — which sounds absurd, because it is for home use. But the real advances are elsewhere.
Multi-Link Operation (MLO) is the genuinely interesting part. MLO lets a single device connect on two or three bands simultaneously and aggregate them. So instead of a device being on 5 GHz or 6 GHz, it can be on both at once, using whichever channel has the cleaner path. On a crowded network, this means more stable throughput and lower latency — not just faster peak speeds.
Wi-Fi 7 also doubled the channel width to 320 MHz (up from 160 MHz) and moved to 4096-QAM modulation (up from 1024-QAM), which accounts for the big theoretical speed jump. In real-world conditions, on a Wi-Fi 7 router with a Wi-Fi 7 laptop, I’ve seen benchmarks in the 2–3 Gbps range at close range on a clean 6 GHz channel. That’s quick. The latency improvements are real too — under 1ms in some MLO configurations.
The problem: a solid Wi-Fi 7 router (like the TP-Link Deco BE85 or ASUS ZenWiFi BQ16) costs £350–£600+. And you need Wi-Fi 7 client devices — MacBook Pro with M3 chip, certain recent Android flagships — to get the benefit.

Who should get what: a plain decision guide
Stop reading specs. Answer these instead.
Is Wi-Fi 6 enough for a typical family in 2026?
Yes, for the vast majority of households. A family with 10–20 connected devices — phones, smart TVs, laptops, tablets, a console or two — streaming 4K Netflix on multiple screens simultaneously, a couple of people working from home on video calls, kids gaming online. Wi-Fi 6 handles all of that without breaking a sweat. Get a well-reviewed dual-band Wi-Fi 6 router (the TP-Link Archer AX73 at around £120 is solid, or the ASUS RT-AX86U at £180 if you game seriously) and you’re done.
Your existing devices — the ones you already own — are almost certainly Wi-Fi 5 or Wi-Fi 6. A Wi-Fi 7 router won’t make them faster. Your phone doesn’t magically gain Wi-Fi 7 capability because the router has it.
Should you step up to Wi-Fi 6E?
Consider it if: you live in a block of flats where the 2.4 and 5 GHz airspace is genuinely congested (run a Wi-Fi analyser app — if you can see 15+ networks on channel 6, that’s congestion). Or if you have a large home (150m²+) and you want a mesh system that uses 6 GHz as a dedicated backhaul channel between nodes — that’s where 6E mesh systems like the TP-Link Deco XE75 Pro actually shine. The nodes talk to each other on 6 GHz (which clients aren’t competing for), and clients get the full 5 GHz bandwidth.
Also consider 6E if you have a recent Samsung flagship or iPhone 15 Pro and you actually want to use the 6 GHz band for those devices. The experience in close range is noticeably snappier — file transfers over Wi-Fi between a 6E laptop and NAS went from ~350 MB/s to ~600 MB/s in my testing.
When does Wi-Fi 7 make sense?
When you’re building or upgrading a setup that needs to last 5–7 years and you already have (or plan to buy) compatible devices. A home content creator doing large file transfers between a Wi-Fi 7 NAS and a Wi-Fi 7 laptop. A household with multiple 8K TVs (very niche in 2026). Smart home enthusiasts running dozens of IoT devices with tight latency requirements. Or just someone who doesn’t want to buy another router in three years.
If you’re buying a new MacBook Pro M4 or a 2024/2025 Android flagship, Wi-Fi 7 support is increasingly baked in — the Qualcomm Snapdragon 8 Elite supports it, and Apple added it to the M3 MacBook Pro. So the client-side situation is improving faster than many expected.
But if your household’s newest device is a 2021 iPhone 13, you’re wasting £300+ on a Wi-Fi 7 router. Full stop.
The device compatibility reality check
This is the part most buying guides gloss over. Wi-Fi is only as good as the weakest link — and that link is your devices, not your router.
A Wi-Fi 7 router will happily serve your Wi-Fi 5 laptop. But it serves it on Wi-Fi 5 terms. The router doesn’t upgrade the laptop’s radio. So that older device sits on 5 GHz, uses older modulation schemes, and gets speeds roughly equivalent to what it’d get from a Wi-Fi 5 router. The expensive router is wasted on it.
Before spending on a newer standard, check what your most-used devices actually support. On Windows 11: Device Manager → Network Adapters → your Wi-Fi adapter → Properties → Advanced tab → shows 802.11 protocols. On a Mac: hold Option and click the Wi-Fi menu bar icon — shows “PHY Mode” (e.g., 802.11ax = Wi-Fi 6). On Android, it varies by manufacturer, but your network info in Settings will usually show the Wi-Fi protocol.

What I’d actually buy in mid-2026
Genuinely — for a 3-bedroom house with two adults working from home, a teenager gaming, and roughly 30 smart home devices: I’d go Wi-Fi 6E mesh. Not Wi-Fi 7 yet. Something like the TP-Link Deco XE75 Pro (£230 for a 2-pack) covers the house well, the 6 GHz backhaul is the real upgrade versus single-node routers, and we’re not at a point where client support for Wi-Fi 7 MLO is mainstream enough to justify the premium. Check again in 2027.
Frequently asked questions
Is Wi-Fi 7 backwards compatible with Wi-Fi 6 and Wi-Fi 5 devices?
Yes. Wi-Fi 7 routers are fully backwards compatible — your Wi-Fi 5 phone, Wi-Fi 6 laptop, and Wi-Fi 4 smart plug will all connect without any setup changes. They’ll just connect at the speeds their own hardware supports. You don’t lose anything by getting a newer router; you just won’t gain the flagship speeds unless your devices support the newer standard.
Does Wi-Fi 6E work through walls?
Worse than 5 GHz, yes. The 6 GHz band has shorter range and is more absorbed by walls and floors. If your router and device are in the same room or separated by one internal wall, it’s fine. Across a thick exterior wall or two floors, signal drops significantly. For whole-home coverage on 6 GHz, a mesh system (where each node adds a 6 GHz hop) is much more practical than a single router.
Will a Wi-Fi 7 router make my internet faster?
Only if your internet connection can actually deliver those speeds — and if your devices support Wi-Fi 7. Most UK broadband connections top out at 1 Gbps or below. Wi-Fi 7’s speed advantage shows up in local network transfers (device to NAS, gaming from a local server) and in congested environments where MLO reduces interference. For a standard 500 Mbps fibre connection, Wi-Fi 6 is already the bottleneck — the router isn’t.
What’s the difference between Wi-Fi 6 and Wi-Fi 6E routers?
The “E” means Extended — as in, extended to the 6 GHz band. Functionally, a Wi-Fi 6E router has all the same technology as Wi-Fi 6 (OFDMA, MU-MIMO, WPA3) plus a third radio that broadcasts on 6 GHz. If none of your devices support 6 GHz, a 6E router behaves exactly like a Wi-Fi 6 router — your devices will just connect on 2.4 or 5 GHz as normal.
Should I wait for Wi-Fi 7 to become mainstream before buying a router?
If your current router works, wait. If you need to replace it now, get Wi-Fi 6 or 6E depending on your budget — they’ll serve you well for 4–5 years. Wi-Fi 7 is genuinely better tech, but it’s still in the enthusiast/early adopter phase in 2026. Prices will drop noticeably by 2027–2028 as more devices ship with 7 support built in, making the upgrade easier to justify.
