Wi-Fi 5 vs Wi-Fi 6 on Chromebooks: Speed and Range Compared

What is Wi-Fi 5

Wi-Fi 5, also known by its technical name 802.11ac, is the wireless standard that most Chromebooks used from roughly 2014 through 2019. It operates primarily on the 5 GHz band, with support for the 2.4 GHz band for compatibility. Wi-Fi 5 introduced wider channels and improved modulation techniques that made it a major step forward from the older Wi-Fi 4 standard.

For everyday tasks like browsing the web, checking email, or watching streaming video, Wi-Fi 5 remains perfectly capable. The majority of Chromebooks from the last several years include Wi-Fi 5 radios, and for a single user on a home network, the practical difference between Wi-Fi 5 and Wi-Fi 6 is often small.

The limits of Wi-Fi 5 become noticeable in congested environments. When many devices share the same access point, Wi-Fi 5 handles the traffic less efficiently. Each device takes turns communicating with the router, and as more devices join, the delay grows.

What is Wi-Fi 6

Wi-Fi 6, or 802.11ax, is the successor to Wi-Fi 5 and is now standard on most new Chromebooks. It was designed to improve performance in dense environments, reduce latency, and increase efficiency. Wi-Fi 6 works on both the 2.4 GHz and 5 GHz bands, and it introduces several key technologies that set it apart from Wi-Fi 5.

One of the most important improvements is OFDMA, which allows a single channel to carry data for multiple devices at the same time. Under Wi-Fi 5, each device had to wait its turn. With OFDMA, the router can serve many devices simultaneously, which reduces waiting time and improves performance when many devices are connected.

Wi-Fi 6 also extends the battery life of wireless devices. A feature called Target Wake Time schedules when a device wakes up to send or receive data, so the Wi-Fi radio can stay asleep longer. For a Chromebook, this can translate to better battery life during everyday use.

Chromebooks with Wi-Fi 6 are standard in current models, from entry-level Intel N-series devices to high-end Core models. If you are comparing models, the wireless standard is often listed under the specifications for connectivity.

Speed and range compared

The theoretical maximum speed of Wi-Fi 6 is much higher than Wi-Fi 5, but the real-world advantage depends on your internet plan and your router. If your broadband connection delivers speeds that Wi-Fi 5 already exceeds, the difference will not be visible in day-to-day use.

Range is less about the standard itself and more about the radio design, antenna placement, and the bands used. Wi-Fi 6 does not inherently provide better range than Wi-Fi 5. The 5 GHz band has shorter range than 2.4 GHz, and both standards use these bands. A Chromebook with Wi-Fi 6 might show a stronger signal if the manufacturer paired it with better antennas, but that is a hardware choice, not a standard feature.

What Wi-Fi 6 does improve is performance at the edge of the range. When the signal is weak, Wi-Fi 6 handles packet retransmission more efficiently, so you may see a steadier connection where Wi-Fi 5 would stutter.

If you are choosing between two similar Chromebooks, one with Wi-Fi 5 and one with Wi-Fi 6, the Wi-Fi 6 model is the better long-term investment. It is more likely to stay performant as your household devices multiply and as routers become more advanced.

Latency and gaming

Latency, the delay between sending a request and receiving a response, matters for video calls, cloud gaming, and fast-paced online games. Wi-Fi 6 lowers latency compared to Wi-Fi 5 in several ways. OFDMA reduces queueing delays, and a feature called BSS Coloring helps the router avoid interference from neighboring networks.

For cloud gaming on a Chromebook, low latency is critical. Services that stream games from the cloud require a stable connection with minimal delay. Wi-Fi 6 provides a smoother experience, especially when other devices are using the network at the same time.

Chromebook Plus models, which include at least 8GB of RAM and a more capable processor, are positioned for cloud gaming and demanding tasks. Pairing a Chromebook Plus with Wi-Fi 6 ensures that the network does not become the bottleneck. For more on which models qualify, see our Chromebook Plus guide.

If you play games that require quick reactions, such as action titles or shooters, the difference between Wi-Fi 5 and Wi-Fi 6 can be noticeable. If you only stream video or browse, the latency improvement is less important.

Battery life and efficiency

Wi-Fi 6 is designed to be more power-efficient than Wi-Fi 5. The Target Wake Time feature allows the Chromebook to negotiate schedule with the router, so the Wi-Fi radio can sleep for longer periods between data transfers. For light tasks like checking email or reading web pages, the radio can stay idle most of the time.

This efficiency does not mean that Wi-Fi 6 always uses less power. When streaming a high-bitrate video or downloading a large file, the radio is active for longer and the power draw is comparable. The benefit appears in mixed workloads, where the Chromebook spends much of its time waiting for the network.

For a Chromebook, which is often used on battery for hours at a time, these small efficiency gains can add up. If you regularly use your Chromebook on the go, Wi-Fi 6 is worth having.

Battery life also depends on the processor, display, and other components. A Wi-Fi 6 radio alone will not double your battery life, but it contributes to a more efficient overall package.

How to check what your Chromebook has

If you already own a Chromebook and want to know whether it supports Wi-Fi 6, there are a couple of ways to find out. The simplest is to look up the model specifications on the manufacturer's website. The wireless section usually lists the Wi-Fi generation.

You can also check the system information on the Chromebook itself. Open Settings, then select About ChromeOS, and then Additional details. This page shows the device name and other system information, though it may not directly list the Wi-Fi standard.

A more practical test is to connect to a Wi-Fi 6 router and check the connection details. In the notification area, select the Wi-Fi icon and then your network name. The connection info may show the standard in use, such as Wi-Fi 6 (802.11ax).

If your router is older, a Wi-Fi 6 Chromebook will still work, but it will operate using the older standard. The benefit of Wi-Fi 6 comes when both the Chromebook and the router support it.

What to pick for your use

Questions

Is Wi-Fi 6 worth it on a Chromebook?

Yes, for most buyers. Wi-Fi 6 improves speed, latency, and battery efficiency, and it handles congested networks better. The difference is most noticeable in busy environments or when using cloud services.

Does Wi-Fi 6 have better range than Wi-Fi 5?

No, Wi-Fi 6 does not automatically provide better range. Range depends on the radio and antenna design. Wi-Fi 6 does maintain performance better at the edge of the signal range.

Will a Wi-Fi 6 Chromebook work with an old router?

Yes, Wi-Fi 6 devices are backward compatible with older routers. The Chromebook will connect using the older standard, such as Wi-Fi 5 or Wi-Fi 4.

How can I tell if my Chromebook supports Wi-Fi 6?

Check the manufacturer's specifications page for your model. Look under wireless or connectivity for 802.11ax or Wi-Fi 6. You can also connect to a Wi-Fi 6 router and check the connection details.

Is Wi-Fi 5 still good enough for online classes and video calls?

Yes, Wi-Fi 5 can handle video calls fine. Wi-Fi 6 offers lower latency and steadier performance, which helps if others share your network during calls.
