Does Your Laptop Support 5GHz Wi-Fi? 7 Proven Ways to Find Out

Are you connecting to a router, but your internet speed is slow, even though your provider promises high speeds? Perhaps your laptop simply doesn't support the range. 5 GHz - faster and less congested Wi-Fi frequency compared to traditional ones 2.4 GHzThe difference in speed can reach 3-5 times, and in multi-apartment buildings, where the 2.4 GHz channel is overloaded with neighboring networks, switching to 5 GHz often becomes the only way to get a stable connection.

The problem is that not all laptops—even modern ones—are equipped with dual-band adapters. Manufacturers sometimes cut corners by installing Wi-Fi modules that only operate at 2.4 GHz, especially in budget models. So how do you know if your device supports 5 GHz? In this article, we'll look into it. 7 reliable ways, including checking through the operating system, BIOS, physical inspection of the adapter, and even network traffic analysis. You'll also find a compatibility chart for popular Wi-Fi chips and instructions for Windows 10/11, macOS And Linux.

1. Checking via Device Manager (Windows)

The fastest way for users Windows — Check the Device Manager. Here you can see the Wi-Fi adapter model and its specifications, including supported frequencies.

Open the menu Start, enter device Manager and select the appropriate item. In the window that opens, find the section Network adapters and open it. Among the devices there will be a line mentioning Wireless, Wi-Fi or Network Adapter — this is your module. Right-click on it and select Properties.

• 🔍 Tab General: The full name of the adapter is given here (for example, Intel Dual Band Wireless-AC 7265). If the title contains words Dual Band, AC or AX — the adapter supports 5 GHz.
• 📋 Tab Additionally: find the property Wireless mode (Wireless Mode) or BandIf there are options in the drop-down list 802.11a or 5GHz, your adapter is dual-band.
• ⚠️ Please note: Some adapters (eg. Realtek RTL8188EE) may display 5 GHz support in their properties, but in practice only work at 2.4 GHz. In this case, further verification is required.

If there is no clear indication of 5 GHz support in Device Manager, proceed to the next method. Also, pay attention to equipment identifier (tab Intelligence, property Equipment ID) - it can be used to search for the exact characteristics of the adapter on the Internet.

2. Analyzing the Wi-Fi adapter model via the command line

The command line allows you to obtain detailed information about your network adapter, including supported standards and frequencies. This method is suitable for Windows 7/10/11 and does not require installation of additional software.

Open Command line as administrator (click Win + X and select the appropriate item). Enter the command:

netsh wlan show drivers

Find the block in the results Supported radio types (Radio types supported). If the following are indicated there:

• 📶 802.11a — 5 GHz support confirmed.
• 📶 802.11g And 802.11n - only 2.4 GHz (if not 802.11a).
• 📶 802.11ac or 802.11ax — the adapter supports 5 GHz and modern standards Wi-Fi 5 or Wi-Fi 6.

Also note the line Radio type (Radio types supported). If there is one there [ Yes ] 802.11a, your adapter definitely works at 5 GHz. If it only says [ Yes ] 802.11b/g, then there is no support for the high-frequency range.

3. Checking via System Information (msinfo32)

Utility msinfo32 provides detailed information about your laptop's hardware and software. To use it, click Win + R, enter msinfo32 and press Enter.

In the window that opens, go to the section Components → Network → AdapterHere you'll see a list of all your network devices. Find your Wi-Fi adapter and note the following fields:

• 🔧 Name — the full name of the model (for example, Qualcomm Atheros QCA9377).
• 🔧 Adapter type - if specified Ethernet, this is not your Wi-Fi module.
• 🔧 State — it should be Included.

Copy the adapter name and find its specifications online (for example, on the manufacturer's website or in a database) Wi-Fi Alliance). Most modern chips Intel, Broadcom And Qualcomm Atheros with support 802.11ac or 802.11ax operate at 5 GHz. The exception is some budget models, for example, Realtek RTL8188CE or RTL8188EE, which support 802.11n, but only at 2.4 GHz.

4. Testing the waters: connecting to a 5 GHz network

The most reliable way is to try connecting to a network that operates exclusively on 5 GHz. To do this:

1. 📡 Configure your router to distribute two separate networks: one at 2.4 GHz, the other at 5 GHz (there is usually an option in the router settings Split networks into ranges or Dual Band Smart Connect - it needs to be turned off).
2. 🔄 Restart your router and check the list of available networks on your laptop.
3. 🔍 If you see both networks (for example, MyWiFi_2G And MyWiFi_5G) and you can connect to the network with 5G in the name - your adapter supports 5 GHz.

If the 5 GHz network isn't visible, but you're sure your router is broadcasting it (check on your smartphone or other device), then your laptop doesn't support this band. Also, keep in mind that some adapters may see 5 GHz networks, but cannot connect to them due to driver issues or power saving settings.

⚠️ Note: Some routers hide suffixes by default _2G/_5G in the network name using technology Smart ConnectIn this case, both networks will be displayed under the same name, and the laptop will automatically select the band. To test 5 GHz support, temporarily disable Smart Connect in the router settings.

5. Checking via BIOS/UEFI

In rare cases, the Wi-Fi adapter may be disabled at the BIOS level, preventing the operating system from detecting it. To check this:

1. 🔧 Restart your laptop and enter the BIOS (usually you need to press F2, Del or Esc when loading).
2. 🔍 Find the section Advanced, Configuration or Wireless.
3. 📋 Check if the setting is enabled Wireless LAN, WLAN or Wi-FiIf it is disabled (Disabled), turn it on and save the settings (F10).

In some laptops (for example, Lenovo or HP) The BIOS may also display information about supported Wi-Fi standards. Look for lines like Wireless Mode or Band Support. If it is indicated there Dual Band or 5GHz, the adapter supports high frequency range.

⚠️ Please note: BIOS settings may be reset after updating the firmware or replacing the battery. If Wi-Fi stops working after these actions, check the BIOS first.

6. Physical inspection of the Wi-Fi adapter (for advanced users)

If you're willing to disassemble your laptop, you can visually identify the Wi-Fi module model and find its specifications. This method is suitable for desktop PCs and laptops with a removable back cover.

Unplug your laptop, remove the battery (if possible), and remove the back cover. The Wi-Fi adapter is usually located near the antenna wires (thin black and white cables) and looks like a small circuit board with a connector. M.2 or mini-PCIeIt should have a sticker with the model name, for example:

• 📇 Intel Wireless-AC 9260 - supports 5 GHz.
• 📇 Broadcom BCM43142 - only 2.4 GHz.
• 📇 Qualcomm Atheros QCA6174 — 5 GHz + MU-MIMO.

Take a photo or write down the adapter model, then find its specifications on the manufacturer's website or in the database Wi-Fi AlliancePlease note the supported standards:

If the adapter does not have a sticker or it is worn off, look for the FCC ID marking (e.g. PD9-9260 For Intel 9260). This identifier can be checked in the FCC (Federal Communications Commission) database, where all technical specifications of the device are listed.

7. Testing on macOS and Linux

For users macOS And Linux There are also ways to check for 5 GHz support without disassembling the laptop.

For macOS:

1. 🍎 Click on the Apple logo in the upper left corner and select About this Mac.
2. 🔍 Go to the tab System Report → Net → Wi-Fi.
3. 📋 In the field AirPort Card or Chipset The adapter model will be indicated. For example, Broadcom BCM4360 supports 5 GHz, and BCM4322 - No.

For Linux:

Open the terminal and run the command:

lspci -v | grep -i wireless -A 10

Find the line in the results Kernel driver in use and the adapter model. Then check the supported frequencies with the command:

iw list | grep -A 10"Supported frequencies"

If the output contains blocks with frequencies 5180 MHz–5825 MHz, your adapter supports 5 GHz.
