Nothing derails a workday or a movie night faster than staring at that small red X on the Wi-Fi icon while every browser tab spins uselessly. If your network adapter not working situation has left you disconnected with no clear explanation, you are not alone, and the good news is that this problem is almost always fixable without replacing any hardware.
Quick Answer
A network adapter not working issue is typically caused by an outdated or corrupted driver, a disabled adapter in Device Manager, a damaged network stack, or a power management setting that shuts the adapter off to save battery. The fastest resolution path is to open Device Manager, check for a yellow warning icon or an error code such as Code 10 or Code 43, update or reinstall the driver, then reset the TCP/IP and Winsock stack using Command Prompt. If the adapter is a physical PCIe or USB card, re-seating it often resolves detection failures that software fixes cannot touch.
Why Your Network Adapter Stops Working
Before jumping into fixes, it helps to understand what is actually happening behind the scenes. A wireless network adapter not working is rarely a single, isolated event. It usually falls into one of four categories:
- Driver corruption or incompatibility a Windows update overwrites a working driver with an unstable one.
- Hardware detection failure the operating system cannot see the adapter at all, so no wifi adapters available appears in the network menu.
- Power management interference Windows aggressively powers down the radio to conserve energy, especially on laptops.
4.Stack level corruption — the TCP/IP or Winsock configuration becomes damaged, so even a healthy adapter cannot pass traffic.
Identifying which category applies to your situation saves considerable time, since a driver reinstall will not fix a stack corruption issue, and a stack reset will not fix a physically loose card.
If your Wi-Fi still refuses to connect even after trying the fixes above, the issue may not be limited to the adapter itself. Our WiFi Not Working guide covers 10 proven techniques that look at everything from the router to device level settings.

How to Fix a Network Adapter Not Working Problem, Step by Step
Step 1: Run the Built-In Network Adapter Troubleshooter
Windows includes a network adapter troubleshooter that can automatically detect and correct common configuration errors. Open Settings, navigate to System, then Troubleshoot, then Other Troubleshooters, and run the Network Adapter tool. This automated scan is a reasonable first move whenever you encounter a network adapter problem, since it resolves a meaningful percentage of cases without any manual intervention.
Step 2: Check Device Manager for Warning Icons and Error Codes
Open Device Manager by right clicking the Start button, then expand the Network Adapters category. A functioning adapter should show no icon overlay. A yellow triangle with an exclamation point indicates a driver or configuration conflict, and it is almost always tied to a specific numbered error.
Understanding Error Code 10
Code 10 in Device Manager means Windows has determined that the device cannot start. This is a generic hardware initialization failure, and it frequently appears after a Windows update replaces a driver with an incompatible version, or after a BIOS setting change disables a controller. To resolve it, open the adapter properties, select the Driver tab, and attempt a driver rollback if a Roll Back Driver option is available. If that option is greyed out, proceed to a full uninstall and reinstall of the driver package from the manufacturer.
Understanding Error Code 43
Code 43 means Windows has stopped the device because it reported a problem, which usually points to a deeper firmware or hardware communication fault rather than a simple driver mismatch. This code often appears when a USB wireless adapter draws more power than a port can supply, or when a driver crash leaves the device in a corrupted state. Unplugging the device, waiting fifteen seconds, and reconnecting it to a different USB port frequently clears a transient Code 43. If the code persists, a clean driver reinstall paired with a firmware check on the manufacturer support page is the next logical step.
Step 3: Update or Reinstall the Network Adapter Driver
An outdated or mismatched driver is the single most common reason behind a wifi adapter not working or a windows 10 wifi adapter not working scenario. In Device Manager, right click the adapter, select Update Driver, then choose to search automatically. If Windows reports that the best driver is already installed, visit the manufacturer website directly, since Windows Update does not always carry the newest release.
For a deeper fix, uninstall the driver entirely by right clicking the adapter, selecting Uninstall Device, and checking the box to delete the driver software if presented. Restart the computer, and Windows will attempt to reinstall a fresh driver automatically. This clean reinstall approach resolves a large share of persistent network adapter issues that a simple update cannot touch.
Step 4: Reset the Network Stack with Netsh Winsock and TCP/IP Commands
When the adapter itself appears healthy in Device Manager but you still cannot connect, or the system reports no wifi adapters available despite hardware being present, the underlying network stack is the likely culprit. Open Command Prompt as an administrator and run the following commands in sequence:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
Restart the computer after running these commands. The Winsock reset rebuilds the catalog that governs how applications communicate through network sockets, while the TCP/IP reset restores the stack to its default configuration. Together, these commands resolve a substantial share of cases where a wireless internet adapter not working issue has nothing to do with the physical hardware at all, and everything to do with a corrupted software layer.
Step 5: Adjust Power Management Settings
A surprisingly common cause of an intermittently disappearing wifi network adapter not working symptom is Windows power management shutting the radio off to conserve battery. To check this, open Device Manager, right click the wireless adapter, select Properties, and open the Power Management tab. Uncheck the box labeled Allow the computer to turn off this device to save power. This single adjustment resolves a large portion of laptop wifi adapter not working complaints, particularly on machines that frequently disconnect after sitting idle for a few minutes.
It is also worth checking the Advanced tab on the same properties window for a Roaming Aggressiveness or 802.11 power saving mode setting, since aggressive power profiles can cause the same symptom even after the primary power management box has been unchecked.
Step 6: Re-Seat Physical PCIe or USB Wireless Cards
If none of the software level fixes above resolve the wireless card not working symptom, and Device Manager does not list the adapter under Network Adapters at all, the hardware connection itself may be loose. For desktop systems using a PCIe wireless card, power down the computer fully, disconnect it from the wall outlet, open the case, and firmly reseat the card in its slot, applying even pressure until it clicks into place. For USB wireless adapters, try a different USB port, ideally a rear panel port on a desktop rather than a front panel hub, since front panel headers sometimes deliver inconsistent power.
A loose physical connection produces symptoms that mimic a driver problem with the driver for the wifi adapter, which is why many guides send readers through repeated driver reinstalls without ever addressing the actual root cause. If the adapter appears and disappears from Device Manager as you gently wiggle the cable or card, a hardware reseat rather than a software fix is what the situation calls for.
Step 7: Check for a Disabled Adapter or Airplane Mode
It sounds basic, but a surprising number of internet adapter not working tickets trace back to Airplane Mode being toggled on accidentally, or the adapter being manually disabled in Network Connections. Open the Control Panel, navigate to Network and Sharing Center, then Change Adapter Settings. If the wireless adapter icon appears greyed out, right click it and select Enable. Also check the physical Wi-Fi switch or function key combination on laptops, since many models include a hardware kill switch that a stray keypress can trigger.
Sometimes the adapter works fine, but you still get an authentication error while connecting to a network. For this specific issue, check our Authentication Issue WiFi guide, which offers a separate solution for each device type.
Windows 11 Specific Considerations
Windows 11 introduced a redesigned Quick Settings panel, and a wireless network adapter not working issue on this version sometimes stems from a corrupted Quick Settings cache rather than the adapter itself. If the Wi-Fi toggle in Quick Settings appears unresponsive, restarting the WLAN AutoConfig service through the Services app, found by searching services.msc, frequently restores functionality without a full driver reinsta.
Connectivity issues on laptops are often handled a little differently, since hardware switches and battery settings come into play as well. Our complete Laptop Not Connecting to Wifi guide walks through laptop specific causes and their fixes in detail.

You can reset a network adapter fully through the built in Network Reset tool in Windows Settings, without touching your operating system installation. Go to Settings, then Network and Internet, then Advanced Network Settings, then Network Reset.
Final Thoughts
A network adapter not working situation feels urgent in the moment, but the underlying causes are well understood and almost always resolvable through a methodical process: check Device Manager for error codes, update or reinstall the driver, reset the network stack, adjust power management, and reseat the hardware if nothing else works. Working through these steps in order, rather than jumping randomly between fixes, is the fastest way back online.
After applying these fixes, it is worth confirming whether your internet is actually restored, or the adapter is simply showing as connected. Our Is My Internet Working guide shows how to check this in just 60 seconds.
