How to update Wi-Fi drivers
First decide whether the failure is the wireless adapter, a disabled radio, pairing or password, signal conditions, the access point, or the internet service. A Wi-Fi driver cannot repair a router outage or a physical antenna problem.
For a laptop or prebuilt computer, use the system maker's support page first because wireless packages can be coordinated with power management and antenna hardware. Save the package before removing or changing the connection used to obtain it.

Key Takeaways
- 1
Match the package to the exact wireless adapter, computer model, Windows edition, and architecture.
- 2
Keep an offline copy using Ethernet or a trusted removable drive.
- 3
Test the radio, adapter, local gateway, and internet as separate layers.
- 4
Preserve virtual network adapters and a rollback route.
Identify the wireless adapter and radio
In Device Manager, inspect Network adapters and unknown devices and record the hardware ID, provider, and version. Check airplane mode, the physical wireless switch, keyboard radio key, antenna or signal, and whether nearby networks appear. If Wi-Fi works in the operating system but not one application, investigate that application's settings first.
Download the package through Ethernet or another trusted computer and copy it locally. Confirm the computer maker, adapter model, Windows edition, architecture, and release notes. Avoid a generic bundle that does not identify the wireless chipset.
- Save the installer and network credentials before changing software.
- Run the signed installer or documented local-driver procedure.
- Restart and confirm that the adapter appears without a warning.
Reconnect to the access point
After installation, turn the radio on, select the intended network, enter its password, and test the local gateway. A connection that reaches the gateway but not the internet may have a DNS, router, or service problem. Compare another device on the same network before repeating a driver installation.
If no adapter appears, verify the hardware ID and package architecture and use the maker's recovery instructions. Do not remove every network component: VPN, virtual-machine, and recovery tools can depend on virtual adapters that are unrelated to Wi-Fi.
Check wireless stability after the update
Test sleep and wake, reconnection, multiple networks, signal changes, and the original activity that failed. Record the working version if a new release causes dropouts or a power-management regression, then use supported rollback and report the exact model and version.
- A driver cannot fix a weak signal, failed router, incorrect password, or service outage.
- Do not force a package for a nearby wireless model.
- Keep a wired or removable-media path until testing is complete.
Common Questions
Can I update a Wi-Fi driver without Wi-Fi?
Yes. Download the exact package through Ethernet or another trusted computer and transfer it with local storage or a clean removable drive.
Why is Wi-Fi connected but the internet does not work?
The adapter may be healthy while the gateway, DNS, router, or service is failing. Test the local network and another device before changing drivers.
