Have you ever wondered what generation of WiFi your devices are using? In today’s connected world, understanding your WiFi technology can be a game-changer for speed, performance, and overall internet experience. Knowing whether you’re on WiFi 4 (802.11n) or WiFi 5 (802.11ac) allows you to make informed decisions about your network setup and potential upgrades. Let’s delve into identifying which standard your devices are currently leveraging.
Understanding the Basics of WiFi Standards
Before we dive into specific methods for identifying your WiFi generation, it’s crucial to understand the fundamental differences between WiFi 4 and WiFi 5. These standards represent significant advancements in wireless technology, each offering improved speeds and capabilities.
WiFi 4 (802.11n): A Foundation
WiFi 4, also known as 802.11n, was a major leap forward when it was introduced. It brought about significant improvements in speed and range compared to its predecessors. This standard uses multiple antennas for both sending and receiving data, employing a technology called MIMO (Multiple-Input and Multiple-Output). MIMO allows for simultaneous transmission and reception of data streams, boosting throughput and reducing latency.
WiFi 4 operates on both the 2.4 GHz and 5 GHz frequency bands. The theoretical maximum speed for WiFi 4 is 600 Mbps, though real-world speeds are typically lower due to factors like interference and network congestion.
WiFi 5 (802.11ac): The Speed Booster
WiFi 5, or 802.11ac, built upon the foundation laid by WiFi 4, focusing on even higher speeds and improved efficiency. A key difference is that WiFi 5 primarily operates on the 5 GHz band, which generally experiences less interference than the 2.4 GHz band.
WiFi 5 also introduced wider channel widths, allowing for more data to be transmitted simultaneously. It also enhanced MIMO technology, supporting MU-MIMO (Multi-User MIMO), which allows a router to communicate with multiple devices simultaneously, further improving network performance, particularly in environments with many connected devices. The theoretical maximum speed for WiFi 5 is significantly higher than WiFi 4, reaching up to 3.5 Gbps, although, again, real-world speeds vary.
Methods to Determine Your WiFi Generation
Now, let’s explore practical methods to determine whether you are using WiFi 4 or WiFi 5. These methods range from checking your router’s settings to utilizing your device’s operating system tools.
Checking Your Router’s Configuration
One of the most reliable ways to determine your WiFi generation is by accessing your router’s configuration settings. This usually involves logging into the router’s web interface through a web browser.
Accessing the Router’s Web Interface
The first step is to find your router’s IP address. This is typically the gateway address of your network. You can find this information in your computer’s network settings or by using command-line tools like ipconfig (Windows) or ifconfig (macOS and Linux).
Once you have the IP address, type it into your web browser’s address bar and press Enter. You will be prompted to enter your router’s username and password. If you haven’t changed them, these are usually printed on a sticker on the router itself. Common default usernames and passwords include “admin” and “password.”
Navigating to Wireless Settings
After logging in, navigate to the wireless settings section of your router’s interface. The exact location of these settings will vary depending on your router’s brand and model. Look for sections labeled “Wireless,” “WiFi,” or something similar.
Identifying the WiFi Standard
Within the wireless settings, you should find information about the WiFi standard being used. Look for mentions of “802.11n,” “802.11ac,” or similar terms. If you see “802.11n,” you’re using WiFi 4. If you see “802.11ac,” you’re using WiFi 5. Some routers may also display both, indicating that they support both standards and your device is connected on one of them. Many newer routers will auto-negotiate the best standard supported by the client device.

iOS (iPhone and iPad)
Unfortunately, iOS does not natively provide detailed technical information about the connected WiFi network, including the WiFi standard (802.11n or 802.11ac). There are no built-in tools or settings to directly view this information. Jailbreaking may allow this, but is highly discouraged for security reasons.
Analyzing Link Speed and Theoretical Maximums
While not a definitive method, analyzing the link speed reported by your device can provide clues about the WiFi standard being used. However, keep in mind that link speed is not the same as actual internet speed, and it can be affected by various factors.
Understanding Link Speed
Link speed refers to the data transfer rate between your device and the router. It’s usually measured in Mbps (megabits per second). Higher link speeds generally indicate a faster WiFi standard.
Typical Link Speeds for WiFi 4 and WiFi 5
With WiFi 4, you’ll typically see link speeds ranging from 54 Mbps to 300 Mbps, depending on the number of antennas and channel width. WiFi 5, on the other hand, often provides link speeds of 433 Mbps or higher, potentially reaching several gigabits per second on newer routers and devices.
Caveats
It’s important to note that link speed is just one piece of the puzzle. Factors like distance from the router, interference, and network congestion can all affect the actual performance you experience. Also, some older devices using WiFi 4 might still show “decent” link speeds while not actually taking advantage of the more advanced features of WiFi 5 routers they connect to.
Why Knowing Your WiFi Generation Matters
Understanding whether you’re using WiFi 4 or WiFi 5 is more than just a technical curiosity. It has practical implications for your internet experience.

What’s the easiest way to check which WiFi standard my device is connected to?
The simplest method is usually through your operating system’s network information panel. On Windows, you can open the Command Prompt and type netsh wlan show interfaces. Look for the “Radio type” entry; this will display the WiFi standard your device is currently using, such as 802.11ac (WiFi 5) or 802.11n (WiFi 4). Similarly, on macOS, you can hold the Option key while clicking the WiFi icon in the menu bar. This reveals detailed connection information, including the “PHY Mode,” which indicates the WiFi standard.
However, these methods aren’t foolproof as they depend on the device’s capabilities and how the network is configured. Sometimes, even if your device supports WiFi 5, it might connect using WiFi 4 due to router settings or signal strength. If the information is ambiguous, you might need to consult your router’s configuration page for definitive details.
Does the number of antennas on my router tell me if it’s WiFi 4 or WiFi 5?
The number of antennas on your router alone isn’t a reliable indicator of whether it supports WiFi 4 or WiFi 5. While routers with more antennas often support newer standards, it’s not a direct correlation. Multiple antennas primarily improve signal strength and coverage by using technologies like MIMO (Multiple-Input Multiple-Output), which can be implemented in both WiFi 4 and WiFi 5 routers.
Therefore, relying solely on the antenna count to determine the WiFi standard is misleading. Routers with a single antenna can still support WiFi 5, while older routers might have multiple antennas but only support WiFi 4. Checking the router’s specifications or accessing its administration panel is crucial for accurate information.
How can I determine the WiFi standard supported by my router through its settings?
The most accurate way to determine the WiFi standard your router supports is by accessing its administration panel. Typically, you can do this by typing your router’s IP address into a web browser (often 192.168.1.1 or 192.168.0.1, but check your router’s manual for the correct address). Log in using your administrator credentials.
Once logged in, navigate to the WiFi or Wireless settings section. Look for options related to the wireless mode or standard. This will explicitly state which WiFi standards the router supports, such as 802.11n (WiFi 4) or 802.11ac (WiFi 5). Some routers might even allow you to select which standards to enable, offering options for compatibility with older devices.
What are the main performance differences between WiFi 4 and WiFi 5?
The primary performance difference between WiFi 4 and WiFi 5 lies in their maximum theoretical speeds and efficiency. WiFi 5, also known as 802.11ac, offers significantly faster speeds, often capable of reaching gigabit speeds under ideal conditions, while WiFi 4 (802.11n) is typically limited to several hundred megabits per second. This speed improvement is due to WiFi 5’s use of wider channels (80 MHz and 160 MHz compared to WiFi 4’s 20 MHz and 40 MHz) and more efficient modulation schemes.
Beyond speed, WiFi 5 also boasts improved efficiency in handling multiple devices simultaneously. It incorporates features like MU-MIMO (Multi-User Multiple-Input Multiple-Output) that allows a router to communicate with multiple devices at the same time, reducing congestion and improving overall network performance, especially in homes with many connected devices. WiFi 4 routers, particularly older ones, tend to struggle with numerous simultaneous connections, leading to slower speeds for all users.
Does my device automatically connect to the faster WiFi standard if both WiFi 4 and WiFi 5 are available?
Generally, devices are designed to automatically connect to the WiFi network offering the best performance, and this often means choosing WiFi 5 over WiFi 4 if both are available and the signal strength is comparable. The device evaluates several factors, including signal strength, network congestion, and the supported standards of both the device and the access point (router), before making a connection.
However, this isn’t always guaranteed. Sometimes, a device might stick to WiFi 4 due to a slightly stronger signal, even though WiFi 5 could offer better overall performance. Additionally, device drivers or router settings might influence the connection preference. Manually configuring the device to prioritize WiFi 5 networks or ensuring the router is properly configured can help ensure optimal performance.
If my device is compatible with WiFi 5, does that mean I’m automatically using it?
Just because your device is compatible with WiFi 5 doesn’t automatically guarantee that you’re using it. Your device’s actual connection depends on various factors, including the capabilities of your router and the network configuration. If your router only supports WiFi 4, your device will naturally connect using that standard.
Even if both your device and router support WiFi 5, your device might still connect using WiFi 4 due to signal strength, router settings, or even interference. To ensure you are using WiFi 5, verify that your router is configured to support the 802.11ac standard and that your device is within range of a strong WiFi 5 signal. Sometimes, temporarily disabling WiFi 4 on the router can force compatible devices to connect via WiFi 5.
Is it worth upgrading to a WiFi 5 router if I’m currently using WiFi 4?
Whether upgrading to a WiFi 5 router is worthwhile depends on your specific needs and usage patterns. If you have multiple devices connected to your network simultaneously, especially devices that stream high-definition video or play online games, upgrading to WiFi 5 can significantly improve your network performance by reducing congestion and improving speed. The benefits are particularly noticeable with devices that support MU-MIMO.
However, if you primarily use the internet for basic tasks like browsing and email, and you only have a few devices connected, the improvement might not be as dramatic. Consider the cost of the upgrade, the number of devices you own, and the intensity of your internet usage before making a decision. Also, ensure that your devices are WiFi 5 compatible to take full advantage of the upgrade.
