How to Fix WiFi Driver: Step-by-Step Guide

WiFi driver problems are among the most common reasons a laptop or desktop loses wireless connectivity. The driver is the software that lets Windows talk to your WiFi card. When it’s outdated, corrupted, or incompatible, you might see no networks, weak signals, or constant disconnects. This guide walks you through fixing it on Windows 10 and 11, with steps that work for most other versions too.

What You’ll Need

A Windows PC with WiFi issues
Administrator access (you’ll need to approve changes)
Another internet source (phone hotspot, Ethernet cable, or another PC) to download drivers if your WiFi is completely dead
Patience – some steps require waiting for Windows to search or install

Step-by-Step

Identify your WiFi adapter – Press Windows + X and select Device Manager. Expand Network adapters. Look for something like “Intel Wireless-AC 9560” or “Realtek RTL8821CE”. Write down the exact name – you’ll need it later.
Check for driver issues – In Device Manager, right-click your WiFi adapter and select Properties. Go to the Driver tab. Note the Driver Version and Date. Also check the General tab – if there’s an error code (like Code 10 or Code 56), that confirms a driver problem.
Update the driver automatically – Right-click the adapter again, choose Update driver, then Search automatically for drivers. Windows will look online and install the best match. Wait a few minutes, then restart your PC.
Update the driver manually (if auto fails) – Go to your PC manufacturer’s support site (Dell, HP, Lenovo, etc.) or the adapter maker’s site (Intel, Realtek, Broadcom). Search for your exact model. Download the latest WiFi driver for your Windows version. Run the installer, or in Device Manager choose Browse my computer for drivers and point to the downloaded file.
Uninstall and reinstall the driver – If updating doesn’t work, right-click the adapter in Device Manager, select Uninstall device. Check the box “Delete the driver software for this device” if it appears. Restart your PC. Windows will automatically reinstall a basic driver. Then try updating again with the steps above.
Roll back the driver – If the problem started after a recent update, go to the Driver tab and click Roll Back Driver. If the button is greyed out, you can’t roll back – skip to the next step.
Run the network troubleshooter (bonus) – Go to Settings > System > Troubleshoot > Other troubleshooters > Network Adapter (Windows 11) or Settings > Network & Internet > Status > Network troubleshooter (Windows 10). Run it. It might reset your network stack, which can fix driver-related issues.

Common Mistakes

Downloading from the wrong site – Only use the official manufacturer or PC maker’s site. Third-party driver download sites often bundle malware or outdated drivers.
Skipping the restart – Many driver fixes only take effect after a full restart. Don’t skip it.
Uninstalling without deleting the driver software – If you uninstall but leave the old driver files, Windows may reinstall the same corrupted version. Always check the delete box when available.
Assuming the latest driver is always best – Sometimes a newer driver introduces bugs. If the latest version causes issues, try the previous one.
Not checking Windows updates – Windows Update often includes driver updates. Make sure your system is fully updated before troubleshooting manually.

Tips

Use a phone hotspot – If your WiFi is dead, tether your phone via USB or hotspot to get internet for downloading drivers.
Create a restore point – Before making major driver changes, create a system restore point (search “Create a restore point” in Start). This lets you undo changes if something goes wrong.
Check power management – In Device Manager, double-click your adapter, go to Power Management, and uncheck “Allow the computer to turn off this device to save power.” This prevents Windows from disabling the adapter randomly.
Keep your driver update tool handy – Some manufacturers offer a utility (like Dell SupportAssist or HP Support Assistant) that automatically detects and installs the right drivers. Use it if available.

Troubleshooting

If the steps above didn’t fix your WiFi, try these additional checks:

Check if the adapter is disabled – In Device Manager, if the adapter has a down arrow, right-click and select Enable device.
Use the Windows Hardware and Devices troubleshooter – Search “troubleshoot” in Settings, run the Hardware and Devices troubleshooter. It may detect conflicts.
Check for hardware issues – If the adapter doesn’t appear in Device Manager at all (even with “Show hidden devices”), it might be physically damaged or disabled in BIOS. Restart your PC, press F2/F10/Del to enter BIOS, and look for a Wireless or WLAN option – make sure it’s enabled.
Try a different driver version – Go to the manufacturer’s site and download an older version that was stable. Install it manually.
Reset network settings – In Windows 11, go to Settings > Network & Internet > Advanced network settings > Network reset. In Windows 10, Settings > Network & Internet > Status > Network reset. This reinstalls all network adapters and resets IP configuration. You’ll need to reconnect to WiFi after.
If all else fails, consider a USB WiFi adapter – A cheap USB dongle can bypass the internal card’s driver issues entirely. It’s a practical workaround if your internal card is beyond repair.

Frequently Asked Questions

Why does my WiFi keep dropping even after updating the driver?

This can be due to power management settings (see the tip above), interference, or a hardware fault. Try the power management fix first, then check if the issue persists on other networks.

Can I fix a WiFi driver without internet?

Yes. You can use another PC to download the driver to a USB drive, or use your phone’s USB tethering to share its internet connection. Windows can also install a generic driver from its local cache.

How do I know if my WiFi driver is outdated?

In Device Manager, check the driver date in Properties. Compare it with the latest version on the manufacturer’s site. If it’s years old, an update is likely needed.

Is it safe to use a driver updater program?

It’s safer to use the manufacturer’s own tool (like Dell SupportAssist) or manual download. Third-party driver updaters often install the wrong version or bundle unwanted software.

What does “Code 10” mean on a WiFi adapter?

Code 10 means the device cannot start. This usually indicates a driver problem. Try uninstalling and reinstalling the driver, or rolling back to a previous version.

Will resetting Windows fix my WiFi driver?

Resetting Windows (or reinstalling) will reinstall all drivers, which can fix persistent driver issues. But it’s a last resort – try the steps above first, as a reset removes your apps and settings.
