Troubleshoot Laptop 5GHz WiFi Connectivity
Solving the Mysteries of Laptop 5GHz WiFi Connectivity
Check network adapter compatibility and capabilities
To check the compatibility and capabilities of your network adapter for 5GHz WiFi connectivity, follow these steps:
1. Press the Windows key on your laptop to open the Start menu.
2. Type “cmd” and press Enter to open the Command Prompt.
3. In the Command Prompt window, type “netsh wlan show drivers” and press Enter.
4. Look for the line that says “Radio types supported.” If it includes “802.11a” or “802.11ac,” your network adapter supports the 5GHz band.
5. If your network adapter does not support the 5GHz band, you can consider upgrading your network card or using a USB WiFi adapter that supports 5GHz.
6. If your network adapter supports 5GHz but is not showing any available networks, make sure your router is set to broadcast on the 5GHz band and that your laptop is within range.
7. If you are still experiencing issues, you can try resetting your router or contacting your broadband provider for further assistance.

Update or reinstall network adapter drivers
To update or reinstall network adapter drivers for troubleshooting laptop 5GHz WiFi connectivity, follow these steps:
1. Press the Windows key on your keyboard and type “Device Manager” in the search box. Open the Device Manager from the results.
2. Expand the “Network Adapters” section and locate your wireless network adapter.
3. Right-click on your adapter and select “Update driver.”
4. Choose the option to search automatically for updated driver software. If an update is found, follow the on-screen instructions to install it.
5. If your network adapter still isn’t working properly, right-click on it again and select “Uninstall device.”
6. Confirm the uninstallation and restart your computer.
7. After your computer restarts, Windows will automatically reinstall the network adapter driver.
8. If the issue persists, you can try using a USB WiFi adapter as an alternative.
9. If none of these steps resolve the problem, it may be an issue with your router or network configuration. Contact your broadband provider for further assistance.
It can also repair causes of the Blue Screen of Death, which can be related to incompatible DLLs, drivers, or Windows bugs. While Fortect cannot guarantee a fix for every issue, it offers a comprehensive solution for many common laptop problems.
Verify router’s 5GHz bandwidth support
To verify if your router supports 5GHz bandwidth, follow these steps:
1. Press the Windows key on your laptop to open the Start menu.
2. Type “cmd” and press Enter to open the Command Prompt.
3. In the Command Prompt, type “netsh wlan show drivers” and press Enter.
4. Look for the line that says “Radio types supported” or “Network adapter mode.” If it mentions “802.11a” or “802.11ac,” your router supports 5GHz.
5. If your laptop supports the 5GHz band but it’s not showing up as an available network, try these options:
a. Make sure your laptop’s Wi-Fi is turned on and functioning properly.
b. Check if your router is set to broadcast the 5GHz band.
c. Move closer to the router to ensure a strong signal.
d. Check for any interference from other devices or Wi-Fi networks.
e. Update your laptop’s Wi-Fi driver.
python
import pywifi
from pywifi import const
def scan_wifi_networks():
wifi = pywifi.PyWiFi()
iface = wifi.interfaces()[0]
iface.scan()
networks = iface.scan_results()
print("Available Wi-Fi networks:")
for network in networks:
ssid = network.ssid
bssid = network.bssid
signal_strength = network.signal
print(f"SSID: {ssid}, BSSID: {bssid}, Signal Strength: {signal_strength} dBm")
scan_wifi_networks()
Make sure you have the `pywifi` library installed before running this code (`pip install pywifi`). This code uses the `PyWiFi` module to scan for available Wi-Fi networks and prints their SSID, BSSID, and signal strength. It can help identify if the laptop is detecting any 5GHz networks.
Enable 5GHz WiFi on Windows 10
To enable 5GHz WiFi on Windows 10, follow these steps:
1. Check if your laptop supports the 5GHz band: Open Device Manager, expand Network Adapters, and look for “802.11n” or “dual-band” in the adapter’s name. If you don’t see these terms, your laptop may not support the 5GHz band.
2. Update the network adapter driver: Right-click on the adapter in Device Manager, select “Update driver,” and follow the prompts to update the driver. This can improve compatibility with the 5GHz band.
3. Adjust network adapter mode: Open Network and Sharing Center, click on “Change adapter settings,” right-click on your WiFi network adapter, and select “Properties.” Under the “Advanced” tab, look for settings related to the 5GHz band and ensure they are enabled.
4. Check your router settings: Log in to your router’s admin panel and make sure it is set to broadcast on the 5GHz band. Refer to your router’s manual for specific instructions.
Change router channel for better connectivity
To change the router channel for better connectivity on your laptop’s 5GHz WiFi network, follow these steps:
1. Open a web browser and enter your router’s IP address into the address bar. The IP address is usually listed on the back or bottom of the router.
2. Log in to your router’s admin panel using the username and password provided by your broadband provider.
3. Look for the wireless settings or WiFi settings section. This may be located under a different tab or menu depending on your router model.
4. Find the option to change the channel for your 5GHz band. The channel selection may be set to “Auto” by default. Change it to a specific channel, preferably one that is less congested in your area.
5. Save the changes and wait for the router to restart.
6. On your laptop, make sure the wireless network adapter is capable of connecting to a 5GHz network. You can check this in the device manager or network settings.
7. Connect to your WiFi network using the new channel. Your laptop should now have a better and more stable connection.
Note: The specific steps may vary depending on your router model and operating system. Consult your router’s user manual or the manufacturer’s website for more detailed instructions.
Connect to 5GHz WiFi on your laptop
- Check your laptop’s wireless capabilities: Ensure that your laptop supports 5GHz WiFi connectivity.
- Update your laptop’s wireless driver: Visit the manufacturer’s website or use Windows Update to download and install the latest wireless driver for your laptop.
- Restart your laptop and router: Sometimes a simple restart can solve connectivity issues, so try restarting both your laptop and router.
- Position your laptop closer to the router: Ensure that your laptop is within range of the router’s signal, as distance can affect the strength and stability of the connection.
