I’ve had a similar issue with my laptop not detecting the 5GHz WiFi signal, so I understand how frustrating it can be. The good news is that there are a few solutions you can try to resolve this problem.
1. Update WiFi Driver: One possible reason for your laptop not detecting the 5GHz WiFi is an outdated or incompatible WiFi driver. To update the driver automatically, follow these steps:
A. Press the Windows key + X on your keyboard and select Device Manager from the menu.
B. In the Device Manager, expand the Network adapters category.
C. Right-click on your WiFi adapter and select Update driver.
D. Choose the option to search automatically for updated driver software.
E. Windows will now search for the latest driver and install it if available.
F. Restart your computer and see if this resolves the issue.
2. Enable 802.11n mode on your WiFi Adapter: Some older WiFi adapters may not support the 5GHz frequency. However, enabling the 802.11n mode can sometimes enable compatibility with the 5GHz band. Here’s how you can do it:
A. Open Device Manager again by pressing the Windows key + X and selecting Device Manager.
B. Expand the Network adapters category and right-click on your WiFi adapter.
C. Select Properties from the context menu.
D. Go to the Advanced tab and look for an option named “802.11n mode” or something similar.
E. Change the value to Enabled if it’s currently Disabled.
F. Click OK and restart your computer to apply the changes.
3. Set bandwidth to 5GHz via Device Manager: In some cases, the default bandwidth setting on your WiFi adapter might be set to 2.4GHz. You can change this setting to 5GHz using the Device Manager:
A. Open Device Manager by pressing the Windows key + X and selecting Device Manager.
B. Expand the Network adapters category and right-click on your WiFi adapter.
C. Select Properties from the context menu.
D. Go to the Advanced tab and look for an option related to bandwidth or frequency.
E. Change the value to 5GHz or 5.2GHz if available.
F. Click OK and restart your computer to apply the changes.
Remember to check if your router is broadcasting the 5GHz WiFi signal and that your laptop’s WiFi adapter supports the 5GHz frequency. If none of the above solutions work, it might be worth considering upgrading your WiFi adapter to a newer model that supports 5GHz.
I hope these steps help you resolve the issue and allow your laptop to detect the 5GHz WiFi signal.
