What Is a WiFi Version?

When people ask “How to Check My Wifi Version?” they are usually referring to one of two things. The first is the WiFi standard that your device’s network adapter supports, such as WiFi 4, WiFi 5, or WiFi 6. The second is the firmware version running on your wireless router, which determines which standards the router can broadcast. Both are important, but they answer slightly different questions.

Your WiFi version is essentially a label for a bundle of technical features. Each new WiFi generation introduces faster theoretical speeds, better handling of multiple devices, improved range, and stronger security. Knowing which version your hardware supports tells you what kind of performance you can realistically expect from your network.

Why You Should Check Your WiFi Version

There are several practical reasons to check your WiFi version. First, it helps you understand whether a slow connection is a hardware limitation or a problem with your internet service provider. If your laptop only supports WiFi 4 but your router broadcasts WiFi 6, your laptop will never reach the speeds your router is capable of delivering.

Second, checking your WiFi version helps you plan upgrades. If you are shopping for a new router, you want to know what your devices can take advantage of. Buying a WiFi 7 router for a home full of WiFi 5 devices may not be worth the premium price.

Third, some apps, games, and smart home devices require a minimum WiFi version to function properly. Knowing your version ahead of time prevents frustrating compatibility surprises.

WiFi Versions Explained

Before diving into the steps, it helps to understand what each WiFi version actually represents. The industry recently switched from confusing technical names like 802.11ac to simpler marketing names like WiFi 5. Here is a quick overview of the major generations.

WiFi 4 (802.11n)

WiFi 4 was released in 2009 and was the first generation to support both the 2.4 GHz and 5 GHz bands. It introduced MIMO technology, which uses multiple antennas to improve throughput. WiFi 4 maxes out at around 600 Mbps under ideal conditions, though real-world speeds are usually much lower.

WiFi 5 (802.11ac)

WiFi 5 arrived in 2014 and operates primarily on the 5 GHz band. It significantly increased speeds and introduced MU-MIMO, allowing routers to communicate with multiple devices simultaneously. Theoretical speeds can reach several gigabits per second, making it a popular standard for streaming and gaming.

WiFi 6 (802.11ax)

WiFi 6 launched in 2019 and focuses heavily on efficiency in crowded environments. It supports both 2.4 GHz and 5 GHz, adds OFDMA for better multi-device handling, and improves battery life on connected devices. WiFi 6E extends this standard into the 6 GHz band for even less congestion.

WiFi 7 (802.11be)

WiFi 7 is the newest generation, offering extremely high throughput, lower latency, and wider channel bandwidth. It is still rolling out, but premium devices and routers already support it. If you are asking “How to Check My Wifi Version?” because you recently bought a flagship device, there is a good chance it supports WiFi 6E or WiFi 7.

How to Check WiFi Version on Windows

Windows makes it relatively easy to find your WiFi version, although the exact steps vary slightly between Windows 10 and Windows 11. Here is the most reliable method using the Command Prompt.

Using Command Prompt

  1. Click the Start menu and type cmd.
  2. Right-click Command Prompt and select Run as administrator.
  3. Type netsh wlan show drivers and press Enter.
  4. Look for the line labeled Radio types supported.

This line will list the standards your adapter supports, such as 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, or 802.11ax. The highest standard listed is your WiFi version. If you see 802.11ax, you have WiFi 6. If you see 802.11ac, you have WiFi 5.

Using Windows Settings

You can also check through the Settings app. Go to Settings, then Network and Internet, then WiFi, and click on your connected network. Under Properties, you may see information about the network band and protocol. However, this method shows the version of the connection you are currently using, not necessarily the maximum your adapter supports.

How to Check WiFi Version on Mac

Apple users have a couple of straightforward options. The simplest is to hold the Option key while clicking the WiFi icon in the menu bar. This reveals detailed network information, including the PHY mode, which indicates the WiFi version currently in use.

For a deeper look, open System Settings, go to Network, select WiFi, and click Details. You will see information about your connection. Alternatively, you can open Terminal and run the following command:

system_profiler SPAirPortDataType

This command outputs detailed information about your wireless hardware, including supported PHY modes. Look for entries like 802.11n, 802.11ac, or 802.11ax to determine your WiFi version.

How to Check WiFi Version on iPhone

iPhones do not display the WiFi version in a simple settings menu, but you can still figure it out. The most direct method is to check your iPhone model’s specifications on Apple’s website. For example, the iPhone 11 and later support WiFi 6, while the iPhone 15 Pro supports WiFi 6E.

If you want to check the version of the network you are currently connected to, you can use a third-party app from the App Store that reads network details. Some apps display the PHY mode of your current connection, which corresponds to the WiFi version. Keep in mind that this shows the negotiated standard between your phone and the router, which may be lower than your phone’s maximum capability.

How to Check WiFi Version on Android

Android devices vary by manufacturer, but there are a few common approaches. Many Android phones display WiFi details under Settings, then Network and Internet, then WiFi. Tap your connected network and look for an option like Advanced or Network details. Some manufacturers show the protocol directly, while others do not.

If your phone does not display this information natively, you can use a free app such as WiFi Analyzer or similar tools from the Play Store. These apps can show the PHY mode and other technical details of your current connection. As with iPhone, this reflects the connection’s negotiated standard rather than the absolute maximum your hardware supports.

For the definitive answer, check your device’s specifications on the manufacturer’s website. Searching your phone model plus “WiFi standard” usually returns the supported version quickly.

How to Check WiFi Version on Your Router

Your router’s WiFi version is just as important as your device’s. To check it, log into your router’s admin panel. The address is usually something like 192.168.1.1 or 192.168.0.1, and it is often printed on a sticker on the bottom of the router. Enter your admin username and password, then look for a section labeled Wireless, WiFi Settings, or Advanced.

Within these settings, you should see options for the wireless mode or standard. It may say 802.11n/ac/ax, or it may use the friendly names WiFi 4, WiFi 5, or WiFi 6. Some routers also display this information on the product label or in the user manual.

If you are not sure which router you have, search the model number printed on the device. The manufacturer’s product page will list the supported WiFi standards.

WiFi Version Comparison Table

The table below summarizes the key differences between the major WiFi versions so you can quickly compare them.

WiFi Version Technical Name Release Year Frequency Bands Theoretical Max Speed
WiFi 4 802.11n 2009 2.4 GHz, 5 GHz 600 Mbps

WiFi 7 802.11be 2024 2.4, 5, 6 GHz 46 Gbps

Keep in mind that theoretical speeds are best-case scenarios. Real-world performance depends on your environment, interference, distance from the router, and the number of connected devices.

Troubleshooting Common Issues

Sometimes, even after following the steps above, you may run into confusion. Here are a few common issues and how to resolve them.

Your Adapter Shows an Older Version Than Expected

If you expected WiFi 6 but only see 802.11ac, your network adapter may be the bottleneck. Some laptops ship with WiFi 5 adapters even when the processor supports newer standards. In this case, you may be able to upgrade the adapter if it is not soldered to the motherboard.

Your Router Limits Your Connection

Even if your device supports WiFi 6, an older router will force the connection down to its highest supported standard. Check your router’s version and consider upgrading if it is more than five years old.

Firmware Is Out of Date

Sometimes the hardware supports a newer standard but the firmware has not been updated. Check your router manufacturer’s website for firmware updates. Updating firmware can unlock features and improve stability.

Tips and Best Practices

Here are some practical tips to get the most out of your WiFi setup after you have checked your version.

  • Match your hardware. For the best experience, your router and devices should support the same WiFi version.
  • Use the 5 GHz or 6 GHz band. These bands offer faster speeds and less interference than 2.4 GHz, though with slightly shorter range.
  • Keep firmware updated. Router manufacturers regularly release updates that improve performance and security.
  • Position your router well. Central placement, away from walls and appliances, improves coverage regardless of WiFi version.
  • Consider a mesh system. If you have a large home, a mesh WiFi system can eliminate dead zones more effectively than a single router.
  • Do not overpay for features you cannot use. If all your devices are WiFi 5, a WiFi 7 router will not deliver WiFi 7 speeds to them.
