Wi-Fi Generations Compared: Which One Should You Buy?

What generations mean on a listing

A router listing title names the Wi-Fi generation the router supports: Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E, or Wi-Fi 7. Those names come from the Wi-Fi Alliance, the organization that certifies Wi-Fi products. The Alliance describes each generation as a set of features that work together across the 2.4 GHz, 5 GHz, and 6 GHz bands.

The word on the listing is a label, not a promise of speed or coverage. Two listings with the same generation can be very different in bands, speed class, and pack size. The generation tells you what technology the router supports, while the rest of the title tells you how it is arranged.

The Wi-Fi Alliance also uses generation names alongside the older 802.11 names. A listing may show both, such as a title that includes "AX" for Wi-Fi 6 or "BE" for Wi-Fi 7. The generation name is the simpler way to compare listings, but the 802.11 letters still appear on many boxes and are worth knowing as equivalent labels. For a deeper look at one generation, see Wi-Fi 6E explained.

• Wi-Fi 5 is the name for 802.11ac, introduced in 2014.
• Wi-Fi 6 is the name for 802.11ax, introduced in 2018.
• Wi-Fi 6E is Wi-Fi 6 extended into the 6 GHz band.
• Wi-Fi 7 is the current generation, introduced in 2024.

Wi-Fi 5 listings: what you are looking at

Wi-Fi 5 listings are the oldest generation in common circulation. The Wi-Fi Alliance describes Wi-Fi 5 as offering higher capacity and improved power management, and most Wi-Fi 5 products are dual-band, operating in both the 2.4 GHz and 5 GHz bands.

On a listing, a Wi-Fi 5 router usually shows "AC" in the model name, such as AC1750 or AC2600. That number is the speed class, a sum of the stated link rates, not a speed you will see. A Wi-Fi 5 listing may also say "dual-band" because the 5 GHz band is the main selling point of the generation.

Wi-Fi 5 is an older generation, but it still appears in budget tiers and in pack. For a home where every device is a few years old, a Wi-Fi 5 listing can still match what the devices support. See the dual-band router guide for common entry-level options.

Wi-Fi 6 listings: the current mainstream

Wi-Fi 6 listings are the most common in the catalogue. The Wi-Fi Alliance says Wi-Fi 6 delivers higher data rates and greater capacity, with features that support dense environments. On a listing, Wi-Fi 6 appears as "AX" in the model name, such as AX3000 or AX5400.

The Wi-Fi 6 feature set is what you see in the bullet list: OFDMA to share channels, multi-user MIMO for more devices at once, and target wake time for battery efficiency. These are listing terms, not numbers to measure at home. They explain what the router is designed to do, and the maker's page is the place to read how each feature is implemented.

A Wi-Fi 6 listing can be dual-band or tri-band. Dual-band Wi-Fi 6 covers the 2.4 GHz and 5 GHz bands. Tri-band adds a second 5 GHz band, which the listing shows as three bands total.

• Look for "AX" in the model name to identify a Wi-Fi 6 listing.
• Read the band line: dual-band is 2.4 GHz + 5 GHz, tri-band adds a second 5 GHz.
• The speed class after "AX" is a stated sum, not a measured speed.

Wi-Fi 6E listings: the addition of 6 GHz

Wi-Fi 6E is Wi-Fi 6 with the addition of the 6 GHz band. The Wi-Fi Alliance notes that Wi-Fi 6 introduced Wi-Fi in the 6 GHz band in addition to the 2.4 GHz and 5 GHz bands. A Wi-Fi 6E listing almost always says "tri-band" because it has one band at each frequency: 2.4 GHz, 5 GHz, and 6 GHz.

The 6 GHz band is what separates a Wi-Fi 6E listing from a Wi-Fi 6 one. On the title, Wi-Fi 6E routers are also labeled "AXE" instead of "AX", so the model name reads differently. A listing that says "AXE5400" or "AXE7800" is Wi-Fi 6E. Tri-band routers are common in this tier; see best tri-band routers for examples.

For the 6 GHz band to matter, your devices must support it. A phone or laptop made before the band was introduced will connect on 2.4 GHz or 5 GHz. The listing's 6 GHz band is for newer devices that support it.

Wi-Fi 7 listings: the newest label

Wi-Fi 7 listings carry the newest generation label. The Wi-Fi Alliance introduced Wi-Fi 7 in 2024 and describes it as enhancing performance across the 2.4 GHz, 5 GHz, and 6 GHz bands. On a listing, Wi-Fi 7 appears as "BE" in the model name, such as BE550 or BE9300.

The features listed for Wi-Fi 7 include wider channels available in the 6 GHz band, multi-link operation, and a higher quadrature amplitude modulation mode. These are listing terms, not measured numbers. The listing tells you the router supports these features, and the maker's page describes how they work. For the newest generation, compare the best Wi-Fi 7 routers.

Wi-Fi 7 listings are the most likely to be tri-band or quad-band and to include a multi-gig port. The generation label pairs with the highest speed classes in the catalogue. If your devices do not support Wi-Fi 7, the newer features remain unused until you upgrade them.

Your devices decide the generation

The generation that matters is the one your own devices support. A phone, laptop, tablet, or game console has its own Wi-Fi standard, set by the maker. The maker's page for each device states which generation it supports.

A router with a newer generation works with older devices because each generation is backward compatible. The Wi-Fi Alliance describes each new generation as building on the previous ones. A Wi-Fi 7 router will connect a Wi-Fi 5 laptop, but the laptop will use its own generation, not the router's. This backward compatibility is a listing term worth understanding.

If your devices are a mix of generations, the router's generation should match the newest device you care about. A household with a new phone that supports Wi-Fi 7 can benefit from a Wi-Fi 7 router, while a household with older laptops may stop at Wi-Fi 6.

The internet plan and bands

The internet plan sets the ceiling for what the router can deliver over the internet. The plan's speed is a number you read on your provider's plan page, not on the router listing. The router's speed class is the Wi-Fi side, the plan is the internet side, and the lower of the two is what you will see.

Bands are a separate part of the listing. Every generation uses the 2.4 GHz and 5 GHz bands, and Wi-Fi 6E and Wi-Fi 7 add the 6 GHz band. The 2.4 GHz band is the older one, the 5 GHz band is the common one, and the 6 GHz band is the newest. If your budget is flexible, explore the main router guide for more bands and speed class.

When you compare listings by generation, also compare bands and speed class. A dual-band Wi-Fi 6 router and a tri-band Wi-Fi 6E router are different products even though the generation names are close. The band line and the speed class number tell you more about the shape of the router than the generation alone.

Comparing listings by generation

The way to compare a Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 7 listing is to read the same details on each: the generation, the bands, the speed class, the pack size, and the ports. This site's guides are built on those stated details, so the comparison is done without measured numbers.

A listing that says "Wi-Fi 6" and a listing that says "Wi-Fi 7" are not the same product. The generation tells you which features are present. The rest of the title tells you how many bands, how high the speed class, and whether it is a single router or a mesh kit. For a direct comparison, see Wi-Fi 7 vs Wi-Fi 6.

The Wi-Fi Alliance maintains the generation names and describes each one in its public materials. Reading those pages next to the listing is a way to understand what each generation means before you decide.

Questions to ask the maker

After reading a listing, the maker's page is the next place to look. The maker states which generation the router supports, how the bands are arranged, and what the speed class means on that model.

Good questions to ask the maker include: which devices does this router's generation target, what is the band arrangement, and does the speed class assume a single device or several. The maker's page also describes the features in more detail than the catalogue title.

For security settings on a new router, the Wi-Fi Alliance describes certifications like WPA3 as mandatory for certified devices. Follow the maker's manual and read the NIST cybersecurity pages for general guidance. The Wi-Fi Alliance security page is the source for what WPA3 means as a listing term.

What to pick for your situation

Questions

Which Wi-Fi generation should I buy?

Buy the generation that your newest device supports. Check the maker's page for your phone or laptop to see its Wi-Fi standard, then match a router with that generation or the next one up.

Is Wi-Fi 7 always better than Wi-Fi 6?

Wi-Fi 7 is the newer generation with added features, but it only matters if your devices support it. A Wi-Fi 6 router matches older devices just as well, and the listing details like bands and speed class are what really differ.

What does the 6 GHz band mean on a Wi-Fi 6E listing?

Wi-Fi 6E adds the 6 GHz band to the 2.4 GHz and 5 GHz bands. The 6 GHz band is for devices that support it, and the listing shows the router as tri-band when it includes all three.

Do I need a newer router if my internet plan is slow?

The internet plan sets the ceiling. A slower plan works with any generation, but a newer router still benefits the Wi-Fi side of the connection, especially with multiple devices in the home.

Where do I find the generation on a listing?

The generation is in the first words of the listing title, such as Wi-Fi 6 or Wi-Fi 7, and also in the model letters like AX or BE. The title states the generation directly in both ways.
