Dell G15 WiFi Not Working on Windows 11: Intel AX201 Driver Fix

Dell G15 WiFi not working on Windows 11? The wireless adapter disappears from Device Manager, shows limited connectivity, or drops constantly. Dell G15 gaming laptops use the Intel Wi-Fi 6 AX201 or AX211 adapter. After Windows 11 updates, the Intel wireless driver sometimes conflicts with the Windows 11 wireless stack and stops the adapter from connecting. The fix is a clean Intel wireless driver reinstall from Dell Support.

Why Dell G15 WiFi Fails on Windows 11

The Intel AX201 and AX211 are PCIe wireless adapters sharing the M.2 slot with the Bluetooth radio. Driver issues affect both WiFi and Bluetooth simultaneously. Common root causes:

• Intel wireless driver version mismatch after Windows 11 update — Windows Update installs a generic Intel driver that does not have all Dell G15-specific optimizations
• WiFi adapter disabled by power management — Windows 11 aggressive power saving turns off the wireless adapter during sleep and it does not recover correctly
• WLAN AutoConfig service stopped — without this service, Windows cannot manage wireless connections even if the adapter is working
• Interference or signal issue — not a driver problem; weak signal causes slow speed and drops that look like driver failures

Restart WLAN AutoConfig Service First

Open Services (search services.msc). Find WLAN AutoConfig. If stopped, right-click → Start. Set Startup Type to Automatic. This service is required for Windows to manage WiFi connections — if it is stopped, all wireless adapters appear non-functional even with correct drivers.

Fix Dell G15 WiFi: Intel Driver Reinstall

Step 1: Download Dell-Specific Intel Wireless Driver

Go to Dell Support, enter your G15 model, go to Drivers & Downloads → Network → Wireless LAN. Download the Intel Wi-Fi Driver package. Install and restart.

Step 2: Disable Power Saving on the Adapter

Open Device Manager → Network Adapters → right-click Intel Wi-Fi adapter → Properties → Power Management → uncheck Allow the computer to turn off this device to save power. Also go to Advanced tab → set Power Saving Mode to Maximum Performance.

Step 3: Reset TCP/IP Stack

Open Command Prompt as administrator. Run: netsh int ip reset, then netsh winsock reset, then ipconfig /flushdns. Restart. This clears any corrupted network stack settings that prevent WiFi from connecting even with a working driver.

Per Chris B., who is a Software Developer using a Dell G15 5515: “My Dell G15 WiFi kept dropping after the Windows 11 23H2 update. The WLAN AutoConfig service was set to Manual and had stopped — setting it to Automatic and starting it fixed the drops permanently without touching any drivers.”

Frequently Asked Questions

Why does Dell G15 WiFi keep disconnecting on Windows 11?

Disable power saving on the Intel WiFi adapter in Device Manager: Properties → Power Management → uncheck Allow the computer to turn off this device. Also set Power Saving Mode to Maximum Performance in the adapter’s Advanced properties.

Dell G15 WiFi adapter missing from Device Manager — how to fix?

The adapter may be disabled or the driver is missing. Press Fn + F2 on Dell G15 to toggle the wireless radio. Also check Device Manager → View → Show Hidden Devices. If still missing, reinstall the Intel Wi-Fi driver from Dell Support.

How do I update Intel Wi-Fi driver on Dell G15 for Windows 11?

Go to Dell Support, enter your G15 model, Drivers and Downloads, Network, Wireless LAN. Download the latest Intel Wi-Fi driver package. Do not use Intel’s Driver Support Assistant for Dell laptops — always get drivers from Dell Support for your specific model.

Does Dell G15 support WiFi 6E on Windows 11?

Dell G15 models with Intel AX211 support WiFi 6E (6GHz band) on Windows 11. Earlier G15 models with AX201 support WiFi 6 (2.4GHz and 5GHz only). Check your G15 specifications to confirm which adapter is installed.

Conclusion

Dell G15 WiFi issues on Windows 11 start with the WLAN AutoConfig service — confirm it is running and set to Automatic. Then disable power saving on the Intel WiFi adapter in Device Manager. If drops continue, reinstall the Intel Wi-Fi driver from Dell Support and reset the TCP/IP stack using netsh commands. For persistent issues, update the Dell G15 BIOS from Dell Support as some BIOS versions have fixes for Intel AX201/AX211 power management.
