Should I Buy Wi-Fi 5 or 6?


Wi-Fi 5, also known as 802.11ac, offers faster speeds and wider coverage areas than previous WiFi versions. But Wi-Fi 6 (802.11ax) brings even more significant improvements. This article explores the pros and cons of both to help you make an informed buying decision.

Speed and Bandwidth

One of the main determining factors is speed. WiFi 6 supports faster maximum theoretical speeds, higher bandwidth, and less network congestion.

  • WiFi 5 Speed: Up to 3 Gbps
  • WiFi 6 Speed: Up to 9.6 Gbps with 1024 QAM

That’s over 3X faster! WiFi 6 achieves better speeds through technologies like orthogonal frequency-division multiple access (OFDMA) allowing more devices to transmit simultaneously.

Range and Coverage

Faster WiFi speeds are great, but only if your devices can maintain a solid connection throughout your home.

  • WiFi 5 has decent range with typical coverage areas of 1,500 square feet.
  • WiFi 6 boosts signal reach and efficiency for expanded coverage up to 2,500 square feet.

So if you have dead zones in certain areas of your home, WiFi 6 can help with its extended wireless range capabilities.

Device Capacity

With the onslaught of connected smart home gadgets and Internet of Things (IoT) devices, WiFi networks are handling more simultaneous connections.

WiFi 6 includes MU-MIMO (multi-user, multiple-input, multiple-output) allowing simultaneous data transmission to multiple devices at once. As such:

  • WiFi 5 networks support connecting approximately 100-250 devices
  • WiFi 6 can handle over 500 devices on one network

This makes WiFi 6 better suited for dense, high-traffic networks.

Backwards Compatibility

When upgrading home tech, backwards compatibility is always a concern. Can older devices still connect?

The good news is WiFi 5 and WiFi 6 maintain compatibility with even older WiFi 4/802.11n and WiFi 5/802.11ac devices. However, to enjoy the faster WiFi 6 speeds requires hardware with compatible 802.11ax wireless adapters.

So while WiFi 6 routers work with older devices, upgrade adapters to unlock the full benefits.

Key Differences Summary

Feature WiFi 5 WiFi 6
Max Speed 3 Gbps 9.6 Gbps
Range 1,500 sq ft 2,500 sq ft
Device Capacity 100-250 500+
Backwards Compatible Yes Yes

When Should You Upgrade to WiFi 6?

With the above speed, capacity, and coverage improvements, WiFi 6 seems like an easy choice. But upgrading comes at a cost premium. WiFi 6 routers and devices tend to carry higher price tags.

Here are a few instances where paying more for WiFi 6 provides good value:

  • You have an abundance of devices connecting simultaneously
  • Your network suffers dead zones with poor signal strength
  • You frequently transfer large files across devices
  • You stream high bandwidth 4K/8K video content
  • You play multiplayer video games

If none of the above apply, WiFi 5 likely suits most households sufficiently. But future-proof your network for faster speeds with WiFi 6.

The Case for Sticking with WiFi 5

Despite the performance gains with WiFi 6, WiFi 5 remains a solid option at lower price points with wide device support.

Reasons you may opt to stick with WiFi 5:

  • You’re on a strict budget
  • Your internet plan has speeds below 1 Gbps
  • You use less than 100 connected devices
  • You mostly stream HD or lower resolution video
  • You don’t transfer large files between devices often

As long as you aren’t pushing your WiFi 5 router to its limits, it will work reliably for a few more years. No sense overspending!

Key Takeaways on WiFi 5 vs WiFi 6

  • WiFi 6 is up to 3X faster than WiFi 5 with less network congestion
  • It offers expanded signal range for whole home coverage
  • Supports 4X more simultaneously connected devices
  • Ideal for high bandwidth tasks like 4K streaming or large file transfers
  • WiFi 5 still sufficient for smaller homes with fewer devices

Determine your network usage needs. For optimal future-proofing, choose WiFi 6. But sticking with WiFi 5 works for more basic requirements.


While WiFi 6 brings impressive speed, capacity, and range improvements, WiFi 5 remains adequate for many households. Take stock of your network’s usage and devices to determine if paying extra for WiFi 6 warrants the benefits.

With more devices connecting year after year, WiFi 6 helps future-proof home networks. But WiFi 5 still reliable handles everyday online activities. Compare your needs against the key differences outlined to decide if upgrading to WiFi 6 over WiFi 5 fits your budget and requirements.

Frequently Asked Questions on Wi-Fi 5 vs Wi-Fi 6
