Wi-Fi 7 is the current generation of home wireless, and its headline gains — wider channels, the 6 GHz band, and the ability to use two bands at once — only arrive if the device in your hand supports them too. For most households the honest answer is that the router is rarely the part holding things back.
The 6 GHz band is the real change introduced with Wi-Fi 6E and carried into Wi-Fi 7. It is empty compared with the crowded 2.4 and 5 GHz bands, which is what makes it fast in a block of flats where twenty neighbouring networks overlap. It also has wide channels available, so a single device can pull far more throughput than it could two generations ago.
Its weakness is physics. High-frequency signals lose more energy passing through walls and floors than lower ones, so 6 GHz is at its best in the same room or the next one, and falls back to 5 GHz as soon as the path gets difficult. The band is also only permitted for unlicensed use in some countries, and a router will not offer it where regulators have not opened it.
Only a client built for Wi-Fi 6E or Wi-Fi 7 can join a 6 GHz network. Phones and laptops from before about 2020 cannot, and no firmware update changes that, because the radio hardware itself is missing. In a normal home, where the television, the console, the printer and half the phones are older, most of the traffic will keep running on 5 GHz whatever the router is capable of.
Check the specification of the two or three devices you actually care about before buying anything. If none of them lists Wi-Fi 6E or Wi-Fi 7, a new router buys you a better processor and newer management features, not a new band.
It pays off in three situations: a dense building where the 5 GHz band is congested, a home where recent phones or laptops sit close to the router and move large files, and a house being re-equipped anyway, where buying the current generation simply costs little more than the previous one.
It does not pay off as a fix for weak coverage at the far end of a house. That is a placement and topology problem, and another access point connected by cable will do more for it than any change of standard.

One weak room and a tight budget point to an extender. Several weak rooms, or a weak room where the speed also collapses, point to a mesh system…
Moving the broadband is one of the few tasks in a house move with a fixed lead time, and it rarely matches the day the van arrives.
