Low Wi-Fi signal strength can be identified by simply having talook at the signal bars in Wi-Fi icon. or by measuring the Wi-Fi strength.

Low Wi-Fi signal strength on Windows 10

If the range and signal were perfect a few days ago or before an update or reinstall, then probably some configuration has been changed. The latest configuration that came with the update is not aligned with the config that came with your laptop. The easiest and simplest way to overcome this situation is running Network Adapter Troubleshooter.

To start troubleshooting, right-click the Wi-Fi icon from the system tray and select Troubleshoot problems. It might take a while to run the troubleshooter and once it is done, it will display you all the problems with your network adapter. It will also fix them in the background but again there are some problems which will require manual action. If troubleshooter was not able to identify and fix your problem, then you must follow a more targeted solution.

Use the Device Manager

To solve all hardware related issues, we need to take help of Device Manager. Open the device manager, and under Network Adapters find your Wi-Fi adapter. Right-click it and then open Properties. Now under the driver tab, you can see all actions related to drivers. You can try to update or rollback the driver. Or you can disable and re-enable the device to see if your problem has been solved.

If nothing helps, then you need to dig into advanced settings. From this point onwards, it gets a little complex to understand the terms and their configuration as well. You can try searching online for your Wi-Fi adapter and try to follow the instructions mentioned there.

For example, a peculiar fix for RT3290 Wireless Adapter is changing the sensibility option in the advanced tab. Or another fix is changing the default antenna type to Auxiliary. These are some of the things that you will have to try on your computer. You can search the internet and see what other people did who faced the same issue. Make sure you have a created a system restore point, before making any changes to your system.

Change WiFi Roaming Sensitivity

If you wish to improve the Wi-Fi reception and performance on your Windows PC,  you may want to consider changing the WiFi Roaming Sensitivity or Aggressiveness. Roaming Sensitivity is the rate at which your device selects and switches to the nearest available point of access, offering a better signal. It is based on signal strength and quality – and not on the distance to the WiFi point.

Wi-Fi Range

This is one possibility that this has nothing to do with your hardware or drivers but rather the position of your computer with respect to the Wi-Fi router. Your physical location might be an issue for low signal strength. Maybe you want to read our post on how to increase WiFi Speed and Signal strength and coverage area.
