How to switch Wi-Fi to 5 GHz on a laptop: a complete guide with solutions to problems

You are trying to connect to the network Wi-Fi 5 GHz, but the laptop stubbornly clings only to 2.4 GHz — slow and overloaded frequency? Or does it not see the 5 GHz network at all? The problem most often lies not in the router, but in the settings of the device itself. Even if your Wi-Fi adapter supports dual-band mode, by default the system may block access to the high-frequency range due to energy savings, outdated drivers or incorrect network parameters.

In this article we will look at all possible reasons, why the laptop does not switch to 5 GHz, and we will give step-by-step instructions for Windows 10/11, macOS and Linux. You'll learn how to check adapter compatibility, update drivers, change power settings, and even manually set network priority. And if the problem lies in the router, we will tell you what parameters need to be changed in its settings so that the laptop can finally “see” 5 GHz.

Checking whether your Wi-Fi adapter supports 5 GHz

Before you try to switch to 5 GHz, make sure your Wi-Fi module generally supports this range. Many budget laptops (especially older models Lenovo IdeaPad, HP Pavilion or Acer Aspire) are equipped with adapters only for 2.4 GHz. You can check this without disassembling the device.

On Windows open Device Manager (keys Win + X → select the appropriate item) and find the section Network adapters. In the list, look for devices with names like Wireless-AC, Dual Band or 802.11a/n/ac/ax. If the title contains 802.11b/g/n without the letters "a" or "ac" - your adapter only works on 2.4 GHz.

• 🔍 Intel Wireless-AC 9260/9560/AX200/AX210 - support 5 GHz (standards 802.11ac/ax).
• 🔍 Qualcomm Atheros QCA61x4/QCA9377 - usually dual-band, but may require driver updates.
• 🔍 Realtek RTL8188EE/RTL8723BE/RTL8821CE - often limited 2.4 GHz (especially in older laptops).
• 🔍 Broadcom BCM43142/BCM4352 - support 5 GHz, but may conflict with drivers.

On macOS Click on the Wi-Fi icon in the menu bar while holding Option (⌥). Information about the current connection will appear in the drop-down list, including supported standards (802.11a means 5 GHz support). On Linux run the command in the terminal:

lspci -knn | grep -iA3 net

Look for mentions in the output Dual Band or 802.11ac.

⚠️ Attention: If your adapter does not support 5 GHz, the only option is to replace it with a compatible one (for example, Intel AX200 or TP-Link Archer T4U for USB connection). In laptops with a soldered Wi-Fi module (for example, many Apple MacBook or Dell XPS) replacement may not be possible without voiding the warranty.

Configuring the router for correct operation of 5 GHz

Even if the laptop supports 5 GHz, the problem may lie in the router settings. Many models (eg TP-Link Archer C6, ASUS RT-AX55 or Xiaomi Mi Router 4A) hide the 5 GHz network by default or use incompatible encryption settings. Check the following settings:

Parameter	Recommended value	Why is this important
Wireless Mode	802.11a/n/ac or 802.11ax	If it's worth 802.11n, the router can only operate at 2.4 GHz.
Channel Width	20/40/80 MHz (auto)	Narrow width (eg. 20 MHz) limits the speed.
Channel	36, 40, 44, 48 (or car)	Channels 149–165 may not be supported by some adapters.
Security type	WPA2-PSK or WPA3-PSK	WEP or WPA may block connection to 5 GHz.

Also make sure that SSID (network name) for 2.4 GHz and 5 GHz are different. Many routers by default combine networks under one name (Smart Connect at ASUS, One Wi-Fi at Xiaomi), which may prevent the laptop from selecting the desired range. Disable this function in the router settings (section Wireless Network → Smart Connect Settings).

Switch to 5 GHz in Windows 10 and 11

If the adapter and router support 5 GHz, but Windows stubbornly connects to 2.4 GHz, the problem may be with drivers, power settings, or network priorities. Follow this instruction:

Update your Wi-Fi adapter driver|Disable power saving for the adapter|Make sure the 5 GHz network is visible in the list of available ones|Check your router settings (see previous section)-->

Step 1: Update drivers

Outdated drivers are the most common cause of 5 GHz problems. Go to Device Manager, find your Wi-Fi adapter (for example, Intel(R) Wi-Fi 6 AX200), right-click and select Update driver. If Windows does not find updates, download them manually from the manufacturer's website:

• 🖥️ Intel - drivers for AX200/AX210/9260.
• 🖥️ Qualcomm Atheros - for adapters QCA61x4/QCA9377.
• 🖥️ Realtek - for RTL8821CE/RTL8852AE (often require manual installation).

Step 2: Disable Power Saving

Windows limits the performance of the Wi-Fi adapter by default to save battery power. To fix this:

1. Open Control Panel → Power Options → Set up power plan → Change advanced power settings.
2. Find a section Wireless adapter settings → Power saving mode.
3. Set value Maximum performance for both states (battery and mains).

Step 3: Force connection to 5 GHz

If the laptop sees the 5 GHz network, but does not connect to it automatically, you can set the priority manually:

1. Open Settings → Network and Internet → Wi-Fi → Manage known networks.
2. Select your 5GHz network (if displayed) and click Properties.
3. Check the box Connect automatically And Connect even if the network does not broadcast its name (SSID).

⚠️ Attention: If the list of available networks only shows 2.4 GHzdespite the correct router settings, try delete all saved networks on Windows. For this purpose in Command Prompt (Administrator) do:

netsh wlan delete profile name="*" i="*"

After rebooting, the laptop should rescan networks, including 5 GHz.

Setting up 5 GHz on macOS (MacBook, iMac)

On devices Apple (For example, MacBook Pro/Air or iMac) switch to 5 GHz usually happens automatically, but sometimes the system gets stuck on 2.4 GHz due to energy saving or settings errors. Here's how to fix it:

Step 1: Check supported standards

Click on the Wi-Fi icon in the menu bar while holding Option (⌥). In the window that opens, find the line PHY Mode:

• 🔄 802.11ac or 802.11ax — the adapter supports 5 GHz.
• 🔄 802.11n - can work on both bands, but the speed on 5 GHz will be limited.
• 🔄 802.11b/g - only 2.4 GHz.

Step 2: Force connection to 5 GHz

If your MacBook sees both networks (for example, MyWiFi_2G And MyWiFi_5G), but connects to 2.4 GHz, follow these steps:

1. Open System Settings → Network → Wi-Fi → Advanced.
2. On the list Preferred networks delete the network 2.4 GHz (highlight and press –).
3. Add a network 5 GHz manually by specifying SSID and password.
4. Check the box Automatically join this network.

Step 3: Reset network settings

If macOS stubbornly does not see 5 GHz, reset the network settings:

1. Open Terminal and run the commands:

   sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
   sudo rm /Library/Preferences/SystemConfiguration/preferences.plist

2. Restart your Mac.

Solving problems on Linux (Ubuntu, Mint, Fedora)

On Linux switch to 5 GHz may be complicated by the lack of proprietary drivers (especially for adapters Broadcom or Realtek). If your system does not see the 5 GHz network, follow these instructions:

Step 1: Checking supported frequencies

Open a terminal and run the command:

iw list | grep -A 10 "Supported frequencies"

If the output contains lines with 5180 MHz, 5240 MHz etc. - your adapter supports 5 GHz. If not, you will need a replacement or an external USB adapter (for example, TP-Link Archer T4U).

Step 2. Installing drivers

For adapters Broadcom (often found in Dell or HP) install the proprietary driver:

sudo apt update
sudo apt install firmware-b43-installer

For Realtek RTL8821CE (popular in budget laptops) download the driver from GitHub and install manually:

git clone https://github.com/tomaspinho/rtl8821ce
cd rtl8821ce
make
sudo make install
sudo modprobe 8821ce

Step 3: Force connection to 5 GHz

If the adapter supports 5 GHz but Linux connects to 2.4 GHz, edit the config wpa_supplicant:

1. Open the settings file:

   sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

2. Find your network block and add the line:

   freq_list=5180 5240 5320

   (indicates 5 GHz priority frequencies).

3. Restart the service:

   sudo systemctl restart wpa_supplicant

⚠️ Attention: On some distributions (for example, Fedora or Arch Linux) instead wpa_supplicant used NetworkManager. In this case, edit the connection via nmtui or GUI by manually specifying the 5 GHz channel.

What to do if the laptop does not see the 5 GHz network

If you have completed all the steps but the laptop still does not detect the network 5 GHz, the problem may be due to one of the following factors:

• 🔌 Hardware incompatibility — the adapter does not physically support 5 GHz (see section 1).
• 🔌 Regional restrictions — some countries (for example, Russia until 2021) limited the use of 5 GHz channels. Update the router firmware.
• 🔌 Driver conflict - if you installed drivers manually, they could replace the system ones. Try rolling back the driver to Device Manager.
• 🔌 Interference from other devices — Microwaves, cordless phones or nearby routers can jam the signal. Change the 5 GHz channel in the router settings (for example, with 36 on 48).

Diagnostics via command line (Windows)

Open Command line (administrator) and do:

netsh wlan show drivers

Look for the line Supported radio types. If it only says 802.11g And 802.11n - your adapter does not support 5 GHz. If there is 802.11a or 802.11ac, but the network is still not visible, the problem is in the router settings or drivers.

How to check interference on a 5 GHz channel?

Use the utility Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS) to scan the broadcast. If on your channel (for example, 36) too many neighbors, switch to a less busy one (e.g. 149). In urban environments, it is better to choose higher channels 100, since they are used less frequently by household appliances.

Additional tips for stable operation on 5 GHz

Even if you were able to connect to 5 GHz, the connection may be unstable. Here's how to improve its quality:

• 📶 Router location - 5 GHz passes through walls worse. Place the router in an open space, raise it higher (for example, on a cabinet).
• 📶 Updating the router firmware - go to the router control panel (usually at 192.168.0.1 or 192.168.1.1) and check for updates.
• 📶 Disabling Power Saving Mode - in Device Manager open the properties of the Wi-Fi adapter, go to the tab Power management and uncheck Allow this device to turn off to save power.
• 📶 Using a USB adapter - if the built-in module is weak, connect an external adapter (for example, ASUS USB-AC56 or TP-Link Archer T3U).

Configuring QoS for traffic priority

If you use your laptop for gaming, streaming, or video calls, set up QoS (Quality of Service) on the router to prioritize 5 GHz traffic:

1. Go to your router's control panel.
2. Find a section QoS or Traffic priority.
3. Add a rule for your laptop (by MAC address or IP) with maximum priority.
4. Set device bandwidth limit to 2.4 GHz (for example, smartphones or smart speakers).

FAQ: Frequently asked questions about switching to 5 GHz

🔹 Why does my laptop see the 5 GHz network but not connect to it?

This may be due to:

• Incompatible security type (for example, the router uses WPA3, and the adapter only supports WPA2). Change your router settings.
• Too wide channel (For example, 160 MHz). Try installing 80 MHz.
• Restricted by MAC address in the router settings. Check the list of allowed devices.

🔹 How do you know what frequency (2.4 or 5 GHz) your laptop is connected to?

On Windows:

1. Open Settings → Network and Internet → Wi-Fi.
2. Click on the current network and view the properties. If the speed is higher 300 Mbit/s, most likely it is 5 GHz.

On macOS:

Hold Option (⌥) and click on the Wi-Fi icon. In the section PHY Mode the standard will be indicated (802.11ac - 5 GHz).

🔹 Is it possible to use 2.4 GHz and 5 GHz at the same time?

Yes, if your router supports simultaneous operation of two ranges (most modern models can do this). In the router settings, enable both bands, but set them different SSID names (For example, MyWiFi_2G And MyWiFi_5G). This way you can manually choose which network to connect to.

🔹 Why is the speed at 5 GHz lower than at 2.4 GHz?

This is paradoxical, but possible for the following reasons:

• Weak signal - 5 GHz passes through obstacles worse. Check the signal level in the adapter settings.
• Interference — if there are many other networks on your channel, the speed drops. Use utilities like Wi-Fi Analyzerto find an available channel.
• Router limitation - some models (for example, budget routers from the provider) artificially limit the speed at 5 GHz.

🔹 How to enable 5 GHz on a laptop with Windows 7?

Windows 7 does not officially support modern standards 802.11ac/ax, but you can:

1. Update the Wi-Fi adapter driver to the latest version from the manufacturer's website.
2. Install update package KB3084905 (adds support 802.11ac).
3. Use an external USB adapter that supports 5 GHz (for example, TP-Link TL-WDN4800).

If all else fails, consider upgrading to Windows 10/11 - this will solve the problem of supporting modern networks.
