WiFi 5 vs WiFi 6: Which Is Better?

Choosing the right wireless router can make a noticeable difference to your internet experience, especially when several devices are connected at the same time. When comparing WiFi 5 vs WiFi 6, it is important to look beyond advertised speeds and understand how each generation handles multiple devices, streaming, gaming, coverage and network traffic.

WiFi 5, also known as 802.11ac, remains capable of handling everyday activities such as browsing, video streaming and online work. WiFi 6, or 802.11ax, introduces technologies designed to make wireless networks more efficient, particularly in busy environments with many connected devices.

So, WiFi 5 vs WiFi 6: which is better? The answer depends on your internet connection, the number of devices you use, what you do online and whether your devices support the newer WiFi standard.

What Is WiFi 5?

WiFi 5 is the consumer name commonly used for the 802.11ac wireless standard.

It was designed to provide significantly higher wireless throughput than previous WiFi generations and primarily operates on the 5 GHz band. WiFi 5 introduced technologies such as wider channels, 256-QAM and MU-MIMO to improve wireless performance.

WiFi 5 is still suitable for many homes and small offices. It can handle activities such as:

• Web browsing
• HD and 4K streaming
• Video calls
• Online gaming
• Social media
• Cloud applications
• Connecting computers and smartphones

However, performance can vary depending on the router hardware, connected devices, signal strength and network congestion.

What Is WiFi 6?

WiFi 6 is the consumer name for the 802.11ax standard. Rather than simply increasing theoretical speed, WiFi 6 focuses heavily on improving network efficiency and handling multiple devices simultaneously. One of its major technologies is OFDMA, which allows a WiFi 6 access point to divide a channel into smaller resource units and serve multiple devices more efficiently.Cisco explains that 802.11ax uses technologies such as OFDMA, 1024-QAM and Target Wake Time to improve wireless efficiency and performance.

WiFi 6 also introduces improvements such as:

• OFDMA
• Enhanced MU-MIMO
• 1024-QAM
• Target Wake Time
• BSS Coloring and improved spatial reuse
• Better efficiency in high-density environments

These features can make a bigger difference when many devices are using the network at the same time.

WiFi 5 vs WiFi 6: Key Differences

The exact capabilities depend on the individual router and client devices, so the WiFi generation alone does not determine real-world performance.

WiFi 5 vs WiFi 6: Speed

Speed is one of the first things people consider when comparing WiFi routers.

WiFi 6 has a higher theoretical maximum data rate than WiFi 5, with the standard commonly cited at up to 9.6 Gbps compared with up to 6.9 Gbps for WiFi 5 under theoretical specifications. However, these numbers should not be interpreted as the actual internet speed a household will experience.

Your actual WiFi speed depends on factors such as:

• Internet plan speed
• Router hardware
• Client device capabilities
• Signal strength
• Distance from the router
• Channel congestion
• Walls and other physical obstacles
• Number of connected devices

Therefore, upgrading to WiFi 6 does not automatically mean your internet connection will become several times faster.

WiFi 5 vs WiFi 6: Multiple Devices

This is one of the most important differences.

Modern homes can have smartphones, laptops, smart TVs, cameras, gaming consoles, tablets, printers and smart-home devices connected at the same time.

WiFi 6 was designed with this type of environment in mind.

Its OFDMA technology allows the router to efficiently divide wireless resources between multiple clients rather than treating every transmission as an individual request for the entire channel. This can reduce waiting and improve network efficiency when several devices are active.

For example, imagine a household where:

• One person is watching Netflix
• Another person is playing an online game
• Someone else is on a video call
• Several phones are connected
• Smart devices are communicating in the background

A WiFi 6 router can be better suited to managing this type of busy network.

WiFi 5 vs WiFi 6 for Streaming

Both WiFi 5 and WiFi 6 can support video streaming.

For a household with only a few devices and a sufficiently fast internet connection, a good WiFi 5 router may provide enough performance for HD or 4K streaming.

However, WiFi 6 can become more useful when several people are streaming or using bandwidth-intensive applications simultaneously because of its improved network efficiency.

If streaming is your main concern, also consider the router’s hardware, coverage and Ethernet ports rather than looking only at whether it is labelled WiFi 5 or WiFi 6.

FGEE has also published a guide covering routers for streaming and gaming that can help when choosing a router for these activities.

WiFi 5 vs WiFi 6 for Gaming

Online gaming is sensitive to latency, connection stability and network congestion.

A faster maximum speed does not automatically mean a lower ping. However, WiFi 6’s improved traffic management can help maintain a more responsive network when several devices are using the connection simultaneously.

For serious gaming, a wired Ethernet connection is still worth considering where practical because it avoids many of the variables associated with wireless connections.

For wireless gaming, however, a properly configured WiFi 6 router can provide a strong option, particularly in a busy household.

Does WiFi 6 Have Better Range Than WiFi 5?

It is important not to assume that WiFi 6 automatically means dramatically greater range.

WiFi range depends on several factors, including:

• Frequency band
• Transmit power
• Antenna design
• Router placement
• Building materials
• Interference
• Channel configuration
• Client device capabilities

WiFi 6 can improve efficiency and performance, but upgrading the WiFi generation alone may not solve coverage problems.

If your main problem is weak signal in certain rooms, you may need a better router position, access point, range extender or mesh WiFi system instead.

FGEE’s guide on how to extend WiFi coverage in large homes explains some of the options available.

Is WiFi 6 More Secure Than WiFi 5?

WiFi 6 supports modern security features including WPA3, although the exact security options depend on the router and client devices.

WPA3 provides stronger security mechanisms than older WPA2 implementations, making it an important consideration when purchasing a new router.

However, buying a WiFi 6 router alone does not guarantee that every device connected to your network will use WPA3. Older devices may continue using older security standards where compatibility requires it.

Should You Upgrade From WiFi 5 to WiFi 6?

You may want to consider WiFi 6 if:

• You are buying a new router
• Your home has many connected devices
• You regularly stream 4K video
• You play online games
• You frequently experience congestion when many devices are active
• You work from home and rely heavily on video conferencing
• You have newer phones, laptops or other devices that support WiFi 6
• You want a newer wireless standard for your network

On the other hand, upgrading may not be urgent if your existing WiFi 5 router provides the coverage, speed and stability you need.

The performance difference also depends on whether your devices support WiFi 6. A WiFi 6 router can work with older WiFi devices, but those devices cannot take advantage of all the newer standard’s capabilities.

What If My WiFi Is Still Slow After Upgrading?

A new router is not always the solution to slow internet.

Slow WiFi can be caused by:

• Poor router placement
• Too much distance between the device and router
• Thick walls
• Wireless interference
• Too many connected devices
• An overloaded router
• Slow internet service from the ISP
• Outdated device hardware
• Incorrect router configuration
