Internet connection speed directly depends on how modern the hardware installed on your device is. Many users encounter a situation where their ISP provides a gigabit connection, but their laptop doesn't deliver even half the speed. This is often due to an outdated connection. network adapter, which is physically incapable of working with new wireless communication standards.
Understanding your hardware's specifications is essential before purchasing a new router or upgrading your home network. If you buy a powerful router with Wi-Fi 6 support, but your laptop only supports Wi-Fi 4, you're simply overpaying for features you won't be able to use. In this article, we'll explore reliable ways to determine the capabilities of your network card.
There are several ways to obtain this information, from reviewing the manufacturer's specifications to using built-in Windows system utilities. We'll cover each method in detail so you can be confident in the data you receive. This will help you make an informed decision about upgrading your network or replacing components.
Understanding Wireless Standards
Before we move on to diagnostics, it's important to understand the standards' labeling. Technologies evolve rapidly, and older designations like 802.11ac may be confusing to the average user. A simpler numbering system is now used, where Wi-Fi 6 stands for sixth-generation technology. Knowing these differences is critical to properly assessing your laptop's potential.
Each new standard brings not only increased speed but also improved connection stability in noisy environments. For example, the transition to the 5 GHz frequency became widespread with the advent of the standard. 802.11acOlder models can only operate on the congested 2.4 GHz frequency, which significantly limits the actual data transfer speed.
⚠️ Please note: Support for the Wi-Fi 6E standard requires not only a compatible adapter but also operation in the 6 GHz band, which is not available in all countries and not on all routers.
For clarity, let's look at the main differences between wireless network generations in the table below. This will help you quickly understand the maximum speed your device can deliver.
| Generation | IEEE standard | Max. speed (theoret.) | Frequencies |
|---|---|---|---|
| Wi-Fi 4 | 802.11n | up to 600 Mbps | 2.4 GHz |
| Wi-Fi 5 | 802.11ac | up to 6.9 Gbps | 5 GHz |
| Wi-Fi 6 | 802.11ax | up to 9.6 Gbps | 2.4 and 5 GHz |
| Wi-Fi 6E | 802.11ax | up to 9.6 Gbps | 2.4, 5 and 6 GHz |
Why is the actual speed lower than stated?
In real-world conditions, speed is always lower than the theoretical maximum due to signal loss, interference from neighboring networks, distance to the router, and provider restrictions.
Checking through Windows Device Manager
The fastest way to find out the model of your network adapter is to use your operating system's built-in task manager. This method doesn't require installing any additional software and provides the exact name of the chip installed in your laptop. Using the model name, you can easily find specifications online.
To start, press the key combination Win + X and select "Device Manager" from the menu that appears. Alternatively, you can right-click the "Start" button and find the desired section there. In the window that opens, find the category Network adapters and expand the list by clicking on the arrow.
You're looking for a line containing the words Wireless, Wi-Fi, 802.11, or brand names like Intel, Realtek, Qualcomm Atheros. For example, if you see the text Intel(R) Wi-Fi 6 AX200 160MHz, then the number 6 and the abbreviation AX indicate support for the modern standard.
- 🔍 Look for the word "AX" in the name - this is a sign of Wi-Fi 6.
- 📡 The presence of "AC" indicates support for Wi-Fi 5.
- ⚙️ If you only see "N" or "Wireless-N", you have Wi-Fi 4.
- 🚫 The absence of the words Wireless or Wi-Fi may mean that the adapter is disabled or the driver is not installed.
Using the command line for detailed diagnostics
For those who prefer to get information directly from the system, the command line is the ideal tool. It allows you to query the driver for a detailed report on its capabilities, including supported protocols and operating modes. This provides a deeper level of diagnostics than simply viewing the driver's name.
Run Command Prompt as administrator. Enter the command netsh wlan show drivers and press Enter. The system will return a large amount of text, but you need to find the line "Radio protocol" or "Radio types supported." This is where all the standards your adapter can physically handle are listed.
netsh wlan show driversIn the list, you will see abbreviations like 802.11b, 802.11g, 802.11n, 802.11ac, or 802.11ax. Availability 802.11ax Confirms Wi-Fi 6 support. If the list only includes 802.11n and older, then high speeds are out of the question. You can also see information about technology support here. MIMO, which affects the stability of the signal.
⚠️ Note: The command line interface may vary depending on your Windows version and locale. Search for the keywords "Radio types" or "Protocol," even if the word order is different from the example.
☑️ Check via CMD
Analysis via PowerShell and system reports
A more powerful alternative to the classic command line is PowerShell. It allows you to display information in a more structured format and filter out unnecessary data. This is useful if the standard output netsh seems too cumbersome or confusing to you.
Open PowerShell and enter the command Get-NetAdapter | Where-Object {$_.InterfaceDescription -like "Wi-Fi"}This will display the basic properties of the wireless adapter. However, to obtain the specific standard version, it's better to use the command netsh wlan show interfaces, which will show the current operating mode and radio type.
Please pay attention to the "Radio type" field. If it says 802.11ax, your laptop is ready for next-generation networks. It also displays your current upload and download speeds, allowing you to evaluate your actual performance at any given moment.
It's important to understand that even if an adapter supports a higher standard, it may still operate in compatibility mode with an older router. Therefore, always check which network you're connected to when troubleshooting. Switching to 5 GHz often automatically activates a faster protocol, if the equipment supports it.
Checking the laptop manufacturer and model specifications
If software methods seem complicated or yield ambiguous results, you can always consult the documentation. The technical specifications of a specific laptop model clearly specify which Wi-Fi module is installed at the factory. This is especially important for new devices, which may feature advanced solutions.
Find the exact model of your laptop (usually written on a sticker on the bottom of the case or in the system dxdiag). Enter this number into a search engine along with the word "specifications." The exact standard will be listed in the "Communications" or "Network" section on the official website.
Manufacturers typically use the following markings in their descriptions:
- 📄 Intel Dual Band Wireless-AC 9560 — Wi-Fi 5 support.
- 📄 Intel Wi-Fi 6 AX201 — Wi-Fi 6 support.
- 📄 Realtek RTL8822BE — often found in budget models with Wi-Fi 5.
- 📄 MediaTek Filogic — new chips with Wi-Fi 6E support.
It's worth keeping in mind that the same laptop model may have different modules installed in different years. Therefore, the year of manufacture of the device plays a significant role. If the laptop is more than 5-6 years old, the likelihood of it having Wi-Fi 6 is virtually zero, as the standard was approved relatively recently.
Critical: If you plan to purchase an external USB adapter for an upgrade, make sure that the USB port on your laptop supports the 3.0 standard (blue inside), otherwise the speed of the new adapter will be limited by the port's bandwidth.Frequently asked questions and compatibility issues
Even knowing their standard, users often encounter network issues. For example, a laptop might support Wi-Fi 6 but not see a 5 GHz network. This is often due to router settings or regional driver restrictions. In some cases, updating the router firmware can help.
Another common problem is a drop in speed when connecting a large number of devices. Older standards like 802.11n don't handle multitasking well. If you have a lot of gadgets in your home, upgrading to Wi-Fi 6 will provide a noticeable improvement in comfort, even if your internet speed from your provider is slow.
Antennas are also worth mentioning. Thin antenna wires are connected to the module inside the laptop. If the laptop has been disassembled or dropped, the connection may be compromised, resulting in a poor signal regardless of the supported standard. In such cases, a software test will show support for high speeds, but there will be no actual connection.
Is it possible to install Wi-Fi 6 on an old laptop?
Yes, there are two ways to do this. The first is to replace the internal module (if it's not soldered to the board and is an M.2 or Mini-PCIe card). The second, simpler option is to use an external USB adapter with Wi-Fi 6 support. However, for the USB adapter to operate at full speed, a USB 3.0 port is required.
Why can't my laptop see the 5 GHz network?
Most likely, your network adapter only supports the 2.4 GHz band (802.11n standard and below). This could also be caused by an incorrect region in the driver settings or the router channel. Some channels in the 5 GHz band are restricted in some countries.
Does Windows version affect Wi-Fi support?
The operating system itself must support the standard (Windows 10 and 11 support Wi-Fi 6 natively). However, drivers play a crucial role. On older Windows 7 systems, new adapters may not work correctly or at all due to a lack of compatible drivers.
