Are you connected to a router, but the internet speed leaves much to be desired, even though your provider promises 300 Mbps? Or are you planning to upgrade your home network to Wi-Fi 6, but you're not sure if your laptop supports the new standard. 802.11ax? The problem may lie in the limitations of the Wi-Fi adapter - its model, supported frequencies or maximum speed.
In this article you will learn how to accurately determine The actual specifications of your laptop's wireless module — from the chip name to the range support 2.4 GHz, 5 GHz or even 6 GHzWe will look at ways to Windows 10/11, Linux And macOSWe'll also show you how to compare adapter data with router settings to optimize your connection. No unnecessary programs or complex commands—just proven methods.
Why is it important to know the specifications of a Wi-Fi adapter?
Many users mistakenly believe that internet speed depends solely on their provider's plan or router model. In fact, Laptop Wi-Fi adapter — it's a bottleneck just like any other link in the chain. Here's why it's critical:
- 🔌 Compatibility of standards: If your adapter only supports Wi-Fi 4 (802.11n), and the router operates in mode Wi-Fi 6 (802.11ax), you will never get the advertised 1 Gbps - a maximum of 150-300 Mbps.
- 📶 Frequency ranges: Adapters that support only
2.4 GHzwill "slow down" in apartment buildings due to channel congestion, whereas5 GHzor6 GHzgive a clean signal. - ⚡ Maximum speed: Even with a perfect signal, the adapter is limited in
300 Mbpswill not be able to transfer data faster, regardless of the tariff. - 🔧 Drivers and firmware: Outdated drivers may limit the adapter's capabilities. For example, Intel AX200 supports Wi-Fi 6, but without the latest software it will work as Wi-Fi 5.
Without accurate adapter information, you risk wasting money on a new router or mesh system without solving the real problem. For example, buying ASUS RT-AX88U (Wi-Fi 6, 6000 Mbps) is pointless if your laptop is equipped with an adapter Broadcom 4313 (Wi-Fi 4, 300 Mbps).
⚠️ Attention: Adapter specifications may vary even within the same laptop model. For example, Lenovo ThinkPad T480 was released with adapters Intel 8265 (Wi-Fi 5) and Intel 9260 (Wi-Fi 5 with 160 MHz support). Check the details specifically for your device.
Method 1: View information in Device Manager (Windows)
The fastest method for users Windows 10/11 - use built-in device ManagerIt will display the adapter's name, which can be used to find full specifications online.
Instructions:
- Click
Win + Xand select device Manager. - Expand the section Network adapters.
- Find the device with the words Wireless, Wi-Fi or Network Adapter (For example, Intel(R) Wi-Fi 6 AX200 160MHz).
- Right click → Properties → tab Intelligence.
- From the drop-down menu, select Equipment ID — there will be codes here
VEN(manufacturer) andDEV(chip model).
Example of equipment ID: PCI\VEN_8086&DEV_2723Using these codes, you can find the exact adapter model on websites like PCIDatabase.
Adapter name (e.g. Qualcomm Atheros QCA9377)
Equipment ID (VEN and DEV)
Driver version (Driver tab)
Device Status (General tab)
-->
If the adapter name contains abbreviations:
- AC - support Wi-Fi 5 (802.11ac).
- AX - support Wi-Fi 6/6E (802.11ax).
- 160MHz - support for a wide channel (increases speed).
- Dual Band - work on
2.4 GHzAnd5 GHz.
⚠️ Attention: In some laptops (especially budget ones), Wi-Fi and Bluetooth are combined into one module. In this case, only one may be displayed in Device Manager. Bluetooth-device - check both sections.
Method 2: Command Prompt (Windows) - Quick and Express Method
If you only need basic data (adapter name and supported standards), one command is enough in Command line.
Open CMD as administrator and enter:
netsh wlan show drivers
Find the block in the results Radio name (adapter name) and Supported radio types (Wi-Fi standards). Example output:
Radio Name: Intel(R) Wi-Fi 6 AX200 160MHz
Supported radio types: 802.11n 802.11ac 802.11ax
This information is enough to understand:
- 🔹 Does the adapter support Wi-Fi 6 (availability
802.11ax). - 🔹 Does it work in the range
5 GHz(if any)802.11ac/ax). - 🔹 Maximum theoretical speed (standard).
For more detailed information, use the command:
netsh wlan show interfaces
The current channel, security type (WPA3, WPA2) and connection speed (Mbps).
Method 3: Specialized utilities (AIDA64, HWiNFO)
For in-depth diagnostics (including chip temperature, firmware version, and hidden features), use third-party programs. The best free options are:
| Program | What does it show? | Link |
|---|---|---|
| AIDA64 | Adapter model, supported standards, maximum speed, chip manufacturer | Official website |
| HWiNFO | Detailed information about the chip, BIOS version, temperature, supported channels | Official website |
| Speccy | Basic data (model, standard), user-friendly interface for beginners | Official website |
Example of a report in AIDA64:
- Network adapter: Intel Wi-Fi 6 AX201
- Standards:
802.11a/b/g/n/ac/ax - Max. speed:
2400 Mbps(theoretical) - Ranges:
2.4 GHz, 5 GHz, 6 GHz(if supported Wi-Fi 6E)
The advantage of utilities is that they show real capabilities of the chip, and not just those used in the current system. For example, an adapter may support 160 MHz, but Windows only uses 80 MHz due to router settings.
⚠️ Attention: In some laptops (eg. Dell XPS or HP Spectre) Manufacturers limit the functionality of Wi-Fi adapters via BIOS. Even if the program shows support Wi-Fi 6E, in practice the range 6 GHz may be blocked.

Method 4: Checking in Linux (terminal)
In distributions Linux (Ubuntu, Mint, Fedora) You can get information about the adapter through the terminal. Use the command:
lspci -v | grep -i network
Or for a more detailed report:
lshw -class network
Example output:
*-network

To find out the supported standards and frequencies, use:
iw list
Look for blocks Supported interface modes And Frequencies.
If there is a line in the output Band 6 — does your adapter support it? 6 GHz (Wi-Fi 6E). Example:
Band 6:
Capabilities: ...
Frequencies: 5935 - 7115 MHz
What to do if Linux doesn't see the Wi-Fi adapter?
If the team lspci does not show the adapter, check:
1. Is the module enabled in the BIOS (on some laptops, Wi-Fi is disabled by a hardware button or a combination) Fn + F2).
2. Is the proprietary driver installed (Broadcom or Realtek may require manual installation).
3. Are there any conflicts with other modules (for example, rfkill may block the adapter).
Method 5: macOS — System Report and Terminal
On MacBook Wi-Fi adapter data is hidden in System reportTo open it:
- Click on the Apple logo → About this Mac.
- Click System report → Net → Wi-Fi.
Here you will see:
- 🔹 Interface map: chip model (eg Broadcom BCM43xx).
- 🔹 Standards: supported protocols (
802.11a/b/g/n/ac/ax). - 🔹 Channels: supported frequencies (
2.4 GHz,5 GHz,6 GHz).
For terminal use the command:
networksetup -listallhardwareports
Look for the block Wi-Fi indicating the adapter model.
On the new ones MacBook Pro/Air with chips Apple M1/M2 The Wi-Fi adapter is integrated into the processor. In the system report, it may appear as Apple Wi-Fi Without details. In this case, the specifications depend on the Mac model:
- M1 (2020): Wi-Fi 6 (802.11ax), to
1200 Mbps. - M2 (2022+): Wi-Fi 6E, support
6 GHz.
How to compare adapter specifications with a router
Knowing your adapter settings is useless without analyzing your router settings. Here's how to optimize your connection:
- Compare standards:
- If the adapter only supports Wi-Fi 4 (802.11n), and the router operates in mode Wi-Fi 6 (802.11ax), turn it on on the router compatibility mode (
802.11n/ac). - If both devices support Wi-Fi 6, activate
802.11axin the router settings.
- If the adapter only supports Wi-Fi 4 (802.11n), and the router operates in mode Wi-Fi 6 (802.11ax), turn it on on the router compatibility mode (
- Check the ranges:
- If the adapter only works on
2.4 GHz, and the router broadcasts5 GHz, turn it off5 GHzor set up separate SSIDs for each band. - For maximum speed use
5 GHz(or6 GHz, if supported).
- If the adapter only works on
- Adjust the channel width:
- Adapters with support
160 MHz(For example, Intel AX200) will give maximum speed only with the same settings on the router. - If the adapter only supports
80 MHz, install on the router80 MHzorAuto.
- Adapters with support
- Outdated firmware may not work correctly with new adapters (for example, Wi-Fi 6E).
An example of optimal settings for the adapter Intel AX200:
| Router parameter | Recommended value | Why |
|---|---|---|
| Wi-Fi standard | 802.11ax (Wi-Fi 6) |
Maximum compatibility and speed |
| Range | 5 GHz (or 6 GHz, if supported) |
Less interference, higher speed |
| Channel width | 160 MHz |
AX200 supports 160 MHz for speed up to 2400 Mbps |
| Security | WPA3 |
More reliable protection, supported AX200 |
⚠️ Attention: Setting the channel width160 MHzmay lead to unstable connections in apartment buildings due to the limited number of non-overlapping channels. In this case, try80 MHz.
