If Wi-Fi is unstable in Windows 11, a driver update can help when the problem is caused by a known adapter bug or compatibility issue. Start with Windows Update or the PC manufacturer’s support page rather than downloading drivers from generic driver websites.
Check Windows Update for a driver
- Open Settings > Windows Update.
- Install normal pending Windows updates.
- Open Advanced options > Optional updates if that section is available.
- Review offered driver updates and install the relevant wireless-network driver when appropriate.
- Restart the PC if Windows requests it.
Use Device Manager
Right-click Start and open Device Manager. Expand Network adapters, right-click the Wi-Fi adapter, and choose Update driver. The automatic search can check the driver sources available to Windows, but it may not find a newer manufacturer package.
Get the driver from the computer manufacturer
For laptops and prebuilt desktops, the PC manufacturer’s support page is often the safest source because its driver has been selected for that model. Search using the exact model or service identifier. For a separately installed Wi-Fi card, use the adapter manufacturer’s official site.
Confirm that the package matches Windows 11 and the correct hardware before installing it.
If Wi-Fi broke after a driver update
Open the adapter’s Properties in Device Manager and check the Driver tab for Roll Back Driver. If available, rollback can restore the previous driver when a newly installed version caused the problem.
Do not uninstall the adapter casually on a PC with no other Internet access
Windows can often reinstall a removed network device after restart, but that is not guaranteed to restore a working driver immediately. If you plan to uninstall/reinstall the adapter, download the correct driver package first or make sure you have another way to get online.
A driver update is not the fix for every Wi-Fi problem
Test other devices on the same network, restart the router when appropriate, check Airplane mode, and determine whether the problem affects one network or every network. Weak signal, router problems, authentication errors, and Internet-provider outages will not be fixed by repeatedly replacing the Wi-Fi driver.
