Wi-Fi 7 vs Wi-Fi 6: What Substantial Upgrades Arrive

What the generation names mean on a listing

On a router listing, Wi-Fi 7 and Wi-Fi 6 are the two generations a shopper meets most often. Wi-Fi 7 is the newer generation: the Wi-Fi Alliance introduced Wi-Fi CERTIFIED 7 in 2024 and describes it as enhancing performance across the 2.4 GHz, 5 GHz and 6 GHz bands. Wi-Fi 6, introduced in 2018, brought features such as OFDMA, multi-user MIMO, 160 MHz channel support, target wake time and 1024 QAM, according to the same source.

The catalogue labels every router by the newest standard it supports. A Wi-Fi 6 router works with Wi-Fi 5 and older devices; a Wi-Fi 7 router works with Wi-Fi 6 and older devices. The new features are used only when the connecting device supports the same generation. A listing that names two standards is the seller's way of describing the product; read the bullet list and the maker's page for the rest.

• The generation word on the title: Wi-Fi 7, 6E, 6 or 5
• The band count: dual-band, tri-band or quad-band
• The speed class, which is a seller's label on the box
• The port line, especially a multi-gig port

Which bands each generation uses

The bands are the radio ranges a router can use: 2.4 GHz, 5 GHz and 6 GHz. The Wi-Fi Alliance describes Wi-Fi 7 as enhancing performance across all three bands. Wi-Fi 6 routers in this catalogue are usually dual-band (2.4 and 5 GHz) or tri-band (2.4, 5 and 6 GHz, the 6 GHz portion often labeled Wi-Fi 6E).

The band count is stated on the listing as dual-band, tri-band or quad-band. A Wi-Fi 6E listing adds the 6 GHz band to Wi-Fi 6; a plain Wi-Fi 6 listing without a 6 GHz word is dual-band. See tri-band versus dual-band and Wi-Fi 6 versus Wi-Fi 6E for how those words read on a listing.

320 MHz channels in the 6 GHz band

The headline Wi-Fi 7 feature a shopper sees on a listing is 320 MHz channels in the 6 GHz band. The Wi-Fi Alliance states that a 320 MHz channel provides twice the throughput of a Wi-Fi 6 160 MHz channel and enables multigigabit device speeds. A 320 MHz channel exists only in the 6 GHz band, so a Wi-Fi 7 router that is dual-band without 6 GHz cannot use it, and the phone, laptop or tablet must also support Wi-Fi 7.

Channel width is not always printed on a listing; the maker's page for the router usually shows it. Compare the stated band and speed class instead. See what is Wi-Fi 7 for the listing terms around this generation.

Multi-link operation as a listing term

Multi-link operation, shortened to MLO on listing bullet points, is a Wi-Fi 7 feature. The Wi-Fi Alliance describes it as supporting more efficient load balancing of traffic among links, resulting in increased throughput and enhanced reliability. In plain words, the router can use more than one band at a time with a device that also supports MLO.

MLO appears on many Wi-Fi 7 listings as a bullet point. A Wi-Fi 6 router or a single-link Wi-Fi 7 router does not carry the term. Check the maker's page to see whether MLO is listed and how many links it supports. See MLO versus single-link Wi-Fi 7 for related words.

Efficiency features in the bullet list

Alongside MLO, Wi-Fi 7 listings often name 4K QAM, 512 Compressed Block Ack and multiple resource units per station. The Wi-Fi Alliance states that 4K QAM achieves 20% higher transmission rates than Wi-Fi 6's 1024 QAM, that 512 Compressed Block Ack improves efficiency and reduces overhead, and that multiple RUs to a single station improves flexibility for spectrum scheduling.

Wi-Fi 6 listings, in turn, name OFDMA, multi-user MIMO, 160 MHz channels, target wake time and transmit beamforming, all described on the Wi-Fi Alliance page. These are listing words; this site compares routers on stated details only. See OFDMA, MU-MIMO and target wake time for what each term means on a listing.

Wi-Fi 7 and Wi-Fi 6 side by side

The table below is built from the Wi-Fi Alliance's descriptions of both generations. It is a comparison of listing terms, not a promise of a speed or a range.

What Wi-Fi 7 means for the devices you already own

A Wi-Fi 7 router connects to older phones, laptops, tablets and smart gadgets. Each device uses its own standard: a Wi-Fi 6 phone uses Wi-Fi 6 features, a Wi-Fi 5 laptop uses Wi-Fi 5 features. The Wi-Fi 7 features on the router matter only for devices that support them.

To know what a device supports, read the maker's page for that device, not the router listing. The router listing tells the router's own standard, bands and speed class. The best router guide explains how to match a router to the devices a household already owns.

How to compare Wi-Fi 7 and Wi-Fi 6 listings

This site compares routers on stated details: standard, bands, speed class, pack size, mesh, multi-gig ports, gaming and travel words. Between a Wi-Fi 7 and a Wi-Fi 6 listing, compare the bands and the speed class first, then the port line.

A Wi-Fi 6 dual-band router often suits a small apartment or a first router on a budget tier. A Wi-Fi 7 tri-band router with a multi-gig port suits a home with newer devices and wired needs. The guides below list picks by stated details: Wi-Fi 7 routers, Wi-Fi 6 routers, and mesh systems.

• Read the title for the generation and the band count.
• Read the bullet list for MLO, 6 GHz and multi-gig words.
• Compare the speed class as a label, not a measured speed.
• Open the maker's page for channel width and port details.

What to pick for your situation

Questions

Is Wi-Fi 7 much newer than Wi-Fi 6?

Yes. The Wi-Fi Alliance introduced Wi-Fi CERTIFIED 7 in 2024, six years after Wi-Fi CERTIFIED 6 in 2018. On a listing, the newer standard appears as Wi-Fi 7, the older as Wi-Fi 6.

Will a Wi-Fi 7 router work with my Wi-Fi 6 phone?

Yes. A Wi-Fi 7 router connects to older devices, and the phone uses its own Wi-Fi 6 features. The Wi-Fi 7-only features are used only when the phone also supports them.

Does every Wi-Fi 7 router use the 6 GHz band?

No. A dual-band Wi-Fi 7 router without 6 GHz cannot use 320 MHz channels. Read the band count on the listing and the maker's page for the channel details.

What does MLO do on a listing?

MLO stands for multi-link operation, a Wi-Fi 7 feature the Wi-Fi Alliance describes as supporting more efficient load balancing of traffic among links for increased throughput and enhanced reliability.

Can a Wi-Fi 6 router be tri-band?

Yes. A tri-band Wi-Fi 6 router uses 2.4 GHz, 5 GHz and 6 GHz, and the 6 GHz portion is usually labeled Wi-Fi 6E.

Does the speed class tell me the real speed of Wi-Fi 7?

No. The speed class is a seller's label, a sum of the radio rates on the box. This site does not measure speed and cannot promise a speed a household will see.

Do Wi-Fi 7 and Wi-Fi 6 differ in security features?

Security words such as WPA3 appear on both generations' listings. What those words mean and how to use them is explained in the maker's manual and in the security materials of the Wi-Fi Alliance and NIST; follow the maker's instructions. This article does not summarize that guidance.
