How do I fix Wi-Fi adapter issues on Windows?
Here are a few quick tricks we recommend you try first:
Restart the computer. Make sure there are no devices in the vicinity that interrupt the functioning of the Wi-Fi adapter or the router. If you find any, remove them. Install the latest version of Windows if there are any pending updates.
In case none work, head to the solutions listed next.
1. Update the network drivers (Internet needed)
Updating the driver will work only if you have an Ethernet cable connection besides your Wi-Fi. If unavailable, download the necessary drivers on another computer or device and run the setup on the affected PC. To make this process faster, we suggest using driver updater software to update all drivers on your PC automatically.
2. Use the built-in troubleshooter
When you’re encountering issues with your Wi-Fi adapter on your PC, a reliable option is the Internet Connections troubleshooter to identify and eliminate the source of the problem. Disclaimer: this program needs to be upgraded from the free version in order to perform some specific actions.
Press the Windows key + I to open Settings, then head to Updates & Security.
Select Troubleshoot from the left pane and click on Additional troubleshooters.
Select Internet Connections and click the Run the troubleshooter button.
Follow further on-screen instructions and let the process finish.
Restart your computer.
3. Reset network adapters
Once done, restart the computer and verify whether the Wi-Fi adapter is still not working
4. Perform a registry tweak with Command Prompt
This should solve the issue, but if you receive the error 0x80004002 after entering the command, this value needs to be deleted slightly differently. Here’s what to do if you receive this error code:
5. Change the adapter settings
6. Reinstall the network adapter
7. Reset your router
Resetting the router can do wonders, as cliche as it sounds. Though the steps to reset the router are different for each manufacturer, every router usually has a reset button. So, find the instructions for your manufacturer and get done with the process.
8. Update the router firmware
For more information, we suggest that you visit our guide on how to update your router firmware guide.
9. Switch to the Maximum Performance mode
Just keep in mind that the Maximum Performance mode will put some extra pressure on your device, so your laptop battery may drain more quicker. But, it should, in all likelihood, fix the problem with the Wi-Fi adapter.

How do I avoid Wi-Fi connection problems?
1. Choose a less crowded channel
2. Move between 2.4 GHz and 5 GHz
If you have a dual-band router, switching between the two frequencies can be a good idea. You can usually find the frequency settings in the Wireless Settings menu on your router, just like in the image above. Just like we mentioned before, they may differ on your device. Therefore, feel free to consult the manual of your device.
3. Remove unwanted devices
You might have forgotten that you gave the router password to some friends, especially neighbors who may still connect to your Wi-Fi network. To get them off your network, go into your router’s settings, look for connected devices, and delete the ones you don’t recognize.
4. Upgrade your device (change the Wi-Fi card)
The Wi-Fi card or adapter is usually embedded in your motherboard, but that doesn’t mean you can’t use an external one. If you conclude that your one is not working correctly, you can use a new Wi-Fi adapter that will fit your needs better.
5. Get the right router for your needs
When talking about your home network, ensure that the router can provide signal coverage wherever you are in the house. If the connection fails from time to time, it’s either a problem with the router itself or the signal power to your device. You can even choose one of the best routers with an internal antenna but remember to stay with your device within range.
6. Keep your drivers updated
As you’ve read in our guide, drivers can cause a lot of mess when it comes to Wi-Fi adapters, and not only, so it’s recommended that you regularly update the network drivers.
7. Pick the correct Wi-Fi hotspot
Although it may sound hilarious, sometimes we can connect to another network by mistake, a slower or a more crowded one. That is why, when you encounter an Internet connection problem, you first need to ensure that you have the correct link from the ISP and that your router or access point is working correctly. After that, check if other devices can connect to the Wi-Fi network; if they do, you can conclude that there might be a problem with your device.
Should I use a 5GHz or 2.4GHz wireless network?
5GHz networks offer incredible speed and less latency, so if you want a fast connection with low ping, this is the better option. However, 2.4GHz offers a better range, and its signal is better at penetrating through obstacles, such as walls. Also, remember that many devices aren’t fully compatible with 5GHz networks. As a basic rule, troubleshoot the most common possible issues and gradually move on to the more complex ones. Once you have managed to fix things, find out how to boost the performance of a Windows PC for a better experience.
