Wi-Fi 6 vs Wi-Fi 5: Worth the Upgrade?

You've probably seen Wi-Fi 6 stickers on new routers and phones. Marketing says it's a game changer. Reality is more nuanced. Here's what's actually different and whether it matters for you.

The naming history

Wi-Fi versions used to have technical names like "802.11n" and "802.11ac." The industry switched to friendlier numbers:

• Wi-Fi 4 = 802.11n (2009)
• Wi-Fi 5 = 802.11ac (2014)
• Wi-Fi 6 = 802.11ax (2019)
• Wi-Fi 6E = Wi-Fi 6 + new 6 GHz band (2021)
• Wi-Fi 7 = 802.11be (2024)

What Wi-Fi 6 actually does better

1. Handles more devices simultaneously

This is the biggest real-world improvement. Wi-Fi 5 routers struggle when 10+ devices are active. Wi-Fi 6 uses a technology called OFDMA that lets the router talk to multiple devices in parallel.

Real example: family of 4 streaming 4K Netflix on different devices. Wi-Fi 5 could stutter. Wi-Fi 6 handles it without breaking a sweat.

2. Faster on devices that support it

Theoretical max: Wi-Fi 6 = 9.6 Gbps. Wi-Fi 5 = 3.5 Gbps.

Real-world max in a typical home: Wi-Fi 6 = 1-2 Gbps. Wi-Fi 5 = 500 Mbps to 1 Gbps.

Both are way faster than most internet plans, so the bottleneck is usually your ISP, not Wi-Fi.

3. Better battery life on phones

Wi-Fi 6 has a feature called Target Wake Time that lets devices sleep more efficiently. Modest improvement.

4. Better in crowded environments

Apartments where you can see 20 neighboring Wi-Fi networks: Wi-Fi 6 handles interference better.

Where the marketing falls short

Wi-Fi 6 advertised speeds are theoretical max under ideal conditions. Real-world speeds depend on:

• Distance from router
• Walls and obstacles
• Interference from other devices
• Your device's Wi-Fi chip (older phones max out at Wi-Fi 5 speeds even with a Wi-Fi 6 router)

Which devices support Wi-Fi 6?

• iPhone 11 (2019) and newer
• Samsung Galaxy S10 (2019) and newer
• Most laptops 2020+
• Newer iPads, MacBooks, Surface tablets

Older devices will still connect to a Wi-Fi 6 router, just at Wi-Fi 5 speeds.

Should you upgrade?

Upgrade now if:

• Your router is 5+ years old
• You have 15 or more devices on Wi-Fi (smart home gear counts)
• Your internet plan is 500 Mbps or faster and you don't get close to that speed on Wi-Fi
• You have Wi-Fi congestion in an apartment
• You stream 4K to multiple devices

Wait if:

• Wi-Fi works fine for your current usage
• Your internet plan is 200 Mbps or slower
• You only have a few devices
• Your current router is recent (2020+)

What about Wi-Fi 6E?

Wi-Fi 6E adds a brand new 6 GHz frequency band. Less crowded, but only newer devices support it. If you're buying a new router today, Wi-Fi 6E is a small price bump worth considering for future-proofing.

What about Wi-Fi 7?

Wi-Fi 7 is the newest. Very fast but expensive routers, and few devices support it as of 2026. For most homes, Wi-Fi 6 or 6E is the sweet spot. Wait 1-2 years for Wi-Fi 7 prices to drop.

Recommended Wi-Fi 6 routers (2026)

• Budget: TP-Link Archer AX55 or similar (~$120)
• Mid-range: Eero 6+ or Asus RT-AX86U (~$200-300)
• Premium / mesh: Eero Pro 6E, Asus ZenWiFi XT8 (~$400+)
