Range
The three current generations. Bands are the important row.
Scroll the table sideways to see every column.
Across all three generations, the thing that has never improved is range. Every generation has been about handling crowded air better and moving more data through it. If your problem is a dead zone, none of this is your fix — go to dead zones instead.
Wi-Fi 6: efficiency, not speed
Wi-Fi 6's real contribution was handling many devices at once rather than making any one device faster. The scheduling improvements mean a router can serve several clients within one transmission opportunity instead of taking strict turns, which matters enormously in a house with thirty connected things and not at all in a house with four.
For most households on plans under a few hundred megabits, Wi-Fi 6 remains genuinely sufficient, and a three-node Wi-Fi 6 mesh will beat a two-node Wi-Fi 7 one at the same price.
Wi-Fi 6E: the same standard, a new band
Wi-Fi 6E is Wi-Fi 6 extended into the 6 GHz band. No new protocol features — just access to a large amount of spectrum nobody was using. In a dense building that is the single most valuable upgrade available, because your neighbors' older hardware physically cannot reach that band.
The trade-off is range: higher frequency means worse penetration, so 6 GHz covers a shorter distance than 5 GHz. In an apartment that is a feature; in a large house it means the 6 GHz band is for nearby devices and backhaul rather than for the far bedroom.
Wi-Fi 7: multi-link operation and wider channels
The Wi-Fi Alliance introduced Wi-Fi CERTIFIED 7 on 8 January 2024. Two changes matter:
Multi-link operation. A Wi-Fi 7 client and access point can establish links on several bands simultaneously and use them in parallel rather than picking one. Higher peak throughput, and — more useful in practice — if one band gets noisy, traffic keeps flowing on another instead of stalling.
320 MHz channels on 6 GHz. Double Wi-Fi 6E's widest, which is only possible because the 6 GHz band has room that 5 GHz never had. Twice the width is roughly twice the throughput when the spectrum is clean and the signal is strong.
Worth knowing
Both ends have to support it
Multi-link operation and 320 MHz channels need Wi-Fi 7 at the device as well as the router. A Wi-Fi 7 router serving a house of Wi-Fi 6 phones delivers Wi-Fi 6 performance. That is not a reason to avoid it — routers outlive phones, so buying the current standard is sensible at equal money — but do not expect anything to change on the day it arrives.
Which one to buy
Plan under about 300 Mbps, coverage problem: Wi-Fi 6, and spend the savings on more nodes.
Dense building, congestion problem: Wi-Fi 6E at minimum — you are buying the 6 GHz band, and 6E is the cheap way to get it.
Gigabit or faster plan, replacing for five years: Wi-Fi 7.
Dual-band Wi-Fi 7 at the same price as tri-band Wi-Fi 6E: buy the 6E. No 6 GHz radio means no 320 MHz channels and only partial multi-link benefit.

What it gets right
+Four 2.5 Gbps LAN ports is rare and makes it a real hub for a wired house
+A 10 Gbps WAN/LAN port means the router will outlive several internet plans
+Tri-band including 6 GHz, so close-range devices get a clean fast lane

Common questions
What is the difference between Wi-Fi 6 and Wi-Fi 6E?+−
Wi-Fi 6E is the same standard with access to the 6 GHz band added. No new protocol features — just a large amount of spectrum that older devices cannot reach, which makes it the cheapest escape from a congested building. The trade-off is shorter range on that band.
Is Wi-Fi 7 faster than Wi-Fi 6E?+−
Potentially, yes — via 320 MHz channels on 6 GHz (double 6E's widest) and multi-link operation, which uses several bands at once. Both need Wi-Fi 7 devices as well as a Wi-Fi 7 router, and neither improves range.
Does Wi-Fi 7 have better range than Wi-Fi 6?+−
No. Range has not improved across any of these generations — transmit power is regulated and physics has not changed. Every generation has improved how much data can move through crowded air, not how far it travels.
Should I skip Wi-Fi 6E and go straight to Wi-Fi 7?+−
If your plan is a gigabit or faster and you expect to keep the hardware five years, yes. If your plan is slower and your problem is congestion rather than throughput, a tri-band Wi-Fi 6E system gets you the 6 GHz band for noticeably less money.
