Mature ecosystem: a large catalog of compatible devices and proven reliability in many households.

For households predominantly streaming HD content, video calls, and light gaming, WiFi 5 routers remain a solid choice if you don’t need the ultimate speed or the latest efficiency features. However, as more devices appear in the home, the limits of WiFi 5 become more noticeable, especially in larger houses or apartments with many walls and competing networks.

WiFi 6 (802.11ax)

WiFi 6 builds on the foundations of WiFi 5 with several important improvements that matter in real life. The hallmark of WiFi 6 is efficiency, which translates into faster and more reliable connections when multiple devices are in use at the same time. Highlights include:

OFDMA (Orthogonal Frequency‑Division Multiple Access) that divides channels into smaller subchannels, letting many devices share channels more efficiently.
MU‑MIMO improvements, enabling more simultaneous streams and better performance for both uplink and downlink traffic.
Target Wake Time (TWT) that helps devices sleep intelligently, conserving battery life on phones, tablets, and smart home gadgets.
Higher order modulation (up to 1024‑QAM) that increases data density and speeds in favorable conditions.

In real terms, WiFi 6 shines in busy homes with many devices, smart speakers, cameras, and gaming consoles. You’ll notice smoother streaming, quicker app loading, and more consistent performance when several people are online at once. If your internet plan sits in the hundreds of megabits per second and you want a more capable network across rooms, WiFi 6 is a sensible upgrade path from WiFi 5.

WiFi 7 (802.11be)

WiFi 7 aims to push the envelope even further by expanding channel width, improving bandwidth efficiency, and enabling new modes of operation. The technology is still rolling out in consumer devices, but the upper bound is compelling. Notable aspects include:

Support for wider channels, including up to 320 MHz, increasing theoretical throughput significantly beyond WiFi 6.
4096‑QAM (16‑bit amplitude modulation) to squeeze more data into each symbol, boosting raw speed where conditions permit.
Multi‑Link Operation (MLO), which allows devices to use multiple frequency bands and channels simultaneously for lower latency and higher reliability.
Enhanced scheduling and interference management to keep performance steady even in dense environments.

In product terms, WiFi 7 is designed to deliver much higher real‑world speed and lower latency, which can benefit activities like 4K/8K streaming, competitive online gaming, and bandwidth‑hungry smart homes. The catch is that it takes time for a large catalog of devices to fully embrace the new standard. If you’re buying a router today, WiFi 7 may offer future‑proofing, but WiFi 6 remains a strong, cost‑effective option for many households right now.

How these changes affect real‑world use

The differences between WiFi 5, WiFi 6, and WiFi 7 aren’t only about peak speeds. Real‑world performance hinges on multiple factors, including your home layout, the number of connected devices, and the plan you receive from your ISP. Consider the following practical impacts:

Household with many devices: WiFi 6 can manage multiple streams more efficiently than WiFi 5, resulting in steadier performance during family movie night or when kids are gaming online.
Smart homes and IoT: With more smart cameras, sensors, and voice assistants, the ability of WiFi 6 to allocate bandwidth intelligently helps prevent congestion, especially in the 2.4 GHz band used by many IoT devices.
Latency and gaming: WiFi 7 promises lower latency and better multi‑link coordination, which can translate into more responsive online gaming and smoother interactive experiences in crowded apartments or shared homes.
Streaming and file transfers: For homes with 4K/8K streaming or large local file transfers across devices, higher throughput in WiFi 6 and WiFi 7 can reduce buffering and shorten transfer times.

Of course, the actual experience depends on your internet plan. If your internet connection tops out at 300 Mbps, upgrading from WiFi 5 to WiFi 6 or WiFi 7 will improve interior performance and reliability, but you won’t see the full speed potential of the newer generations unless your ISP provides higher speeds.

Which generation should you choose?

Choosing between WiFi 5, WiFi 6, and WiFi 7 depends on several practical considerations:

Your current devices: If most of your devices are older, a WiFi 6 router is a solid upgrade from WiFi 5 and will offer noticeable improvements while remaining broadly compatible. If you’re shopping for a new stack of devices (phones, laptops, tablets) with WiFi 7 support, a WiFi 7 router can future‑proof your network for several years.
Network usage patterns: For households with multiple people streaming 4K video, doing video calls, and gaming at the same time, WiFi 6 provides meaningful efficiency gains over WiFi 5. If you anticipate lots of simultaneous modern devices and want the lowest possible latency, WiFi 7 is worth considering.
Budget and availability: WiFi 5 kits are typically cheaper and may suffice for light usage. WiFi 6 options offer a strong balance of price and performance. WiFi 7 devices tend to carry a premium, with broader ecosystem adoption still building out.
Future compatibility: A key advantage of WiFi 6 and 7 is backward compatibility. A Tier‑1 router with WiFi 6 or 7 will usually work with older smartphones and laptops, though you won’t access the higher speeds unless those devices also support the newer standard.

In short: If you’re upgrading an aging network and want tangible gains for everyday tasks, WiFi 6 is usually the most cost‑effective choice. If you’re planning a longer‑term investment to support many modern devices and the latest online activities, and you’re ready to pay a premium, WiFi 7 offers the most headroom for the future.

Upgrade considerations

Before buying a new router or mesh system, keep these practical checks in mind:
