How to Switch Wi-Fi to 5GHz in Windows 10: A Complete Guide with Solutions to Common Problems

• Open Network and Sharing Center (Win + R → ncpa.cpl).
• Find your Wi-Fi adapter, right click and select Disable, then again Turn on.
• Refresh the list of networks in the taskbar (Wi-Fi icon → Refresh).

4. Updating and configuring Wi-Fi adapter drivers

Outdated or incorrect drivers are one of the main reasons why Windows 10 doesn't see the network. 5 GHzEven if the Device Manager shows that the adapter is working properly, its driver may be "cut down" (for example, the laptop manufacturer installed a simplified version).

To update the driver:

1. Open device Manager (Win + X → Device Manager).
2. Expand Network adapters, find your Wi-Fi module and right-click → Update driver.
3. Select Automatic searchIf Windows does not find updates, download the driver from the adapter manufacturer's website (for example, Intel, Qualcomm Atheros, Realtek).

For adapters Intel And Qualcomm It is recommended to use Official drivers from the manufacturer's website, and not those offered by Windows Update. For example, for adapters Intel AX200/AX201 Current drivers can be found on the support page Intel.

⚠️ Attention: After updating the driver, reset the network settings: open Settings → Network & Internet → Status → Network resetThis will delete all saved networks and adapter settings, but often solves connection problems.

5. Setting up power supply for stable 5 GHz operation

Windows 10 limits Wi-Fi adapter power consumption by default, especially on laptops. This can result in the adapter not being able to see the network. 5 GHz or loses connection. To fix this:

1. Open device Manager and find your Wi-Fi adapter.
2. Right click → Properties → Power Management.
3. Uncheck the box Allow the computer to turn off this device to save power.
4. Go to the tab Additionally and set the parameter to Roaming Aggressiveness meaning 1. Lowest (if such a parameter exists).

Also check power plan:

• Open Control Panel → Power Options.
• Choose a plan High performance.
• Click Change power plan settings → Change advanced power settings.
• Find the section Wireless Network Adapter Settings → Power Saving Mode and install Maximum performance.

If the 5 GHz network still doesn't appear after these steps, try disabling power saving mode for USB ports (if you're using an external adapter). To do this, find the section in Device Manager. USB controllers, open the properties of each USB Root Hub and uncheck Allow power off to save power.

6. Alternative ways to connect to 5 GHz

If the standard methods don't work, try one of these options:

• 🔄 Resetting the TCP/IP stack: open command prompt as administrator and run in order:

  netsh int ip reset
  netsh winsock reset
  ipconfig /flushdns

  Afterwards, restart your PC.

• 🖥️ Manually adding a network: if the network 5 GHz if it is not displayed, add it manually:
  1. Open Settings → Network & Internet → Wi-Fi → Manage known networks.
  2. Click Add a new network.
  3. Enter the network name (SSID), security type (WPA2-PSK) and password.
  4. Check the box Connect automatically.

If nothing helps, check if the connection to 5 GHz antivirus or firewallTemporarily disable them and try connecting again. Also, some corporate policies (for example, in domain networks) may restrict the use of certain frequencies.

7. Diagnosing 5 GHz connection issues

If Windows 10 sees the network 5 GHz, but can't connect, try these tips:

For in-depth diagnostics use command line:

• Check your current connection: netsh wlan show interfaces (look for the line Radio type - there should be 802.11ac or 802.11a).
• Check available networks: netsh wlan show networks mode=bssid (will display all networks with frequency indication).
• Check your connection speed: netsh wlan show interfaces | find "Speed".

⚠️ Attention: if in the command output netsh wlan show drivers no support 802.11ac, but the adapter's documentation supports it, this may mean the wrong driver is installed. Uninstall the current driver and reinstall it from the official website.

FAQ: Frequently asked questions about connecting to 5 GHz in Windows 10

My laptop can't see the 5 GHz network, even though the router is broadcasting it. What's wrong?
There may be several reasons:
• The adapter does not support 5 GHz (check the model in Device Manager).
• The adapter driver is outdated or damaged (update it from the manufacturer's website).
• The range is disabled in the router settings. 5 GHz or it is hidden (check the router's web interface).
• Net 5 GHz is broadcasting on a channel that is not supported by your adapter (try changing the channel to 36–48).
How do I know which band (2.4 or 5 GHz) my PC is connected to?
There are two ways:
1. From the command line: run netsh wlan show interfaces and find the line Radio type. If it is indicated there 802.11n or 802.11g - This 2.4 GHz; If 802.11ac or 802.11a - This 5 GHz.
2. Via the router's web interface: look at the list of connected devices - the range is usually indicated there.
Is it possible to force Windows 10 to stop connecting to 2.4 GHz?

Yes, but it requires manual configuration:

1. Delete the network 2.4 GHz from the list of known networks (Settings → Network & Internet → Wi-Fi → Manage known networks).
2. Disable the feature Smart Connect on the router (if there is one) so that the networks are not combined.
3. Use the command line to prioritize your network 5 GHz:

   netsh wlan set profileorder name="5GHz Network Name" interface="Wi-Fi" priority=1

However, Windows can still connect to 2.4 GHz, if the signal 5 GHz weak.
