The Dell Latitude 3440 sees Wi-Fi networks but fails to connect, or connects and immediately drops. The Intel Core i5 1345U model uses the Intel Wi-Fi 6 AX201 module. Corrupted network profiles, driver mismatches, and Windows network stack resets all contribute to this issue.
Forget and Reconnect to the Network
Settings → Network and internet → Wi-Fi → Manage known networks → click your network → Forget. Re-enter the Wi-Fi password to reconnect. This rebuilds a corrupted network profile from scratch.
Reset Network Stack
Open Command Prompt as Administrator. Run: netsh winsock reset. Then run: netsh int ip reset. Restart. This resets Windows TCP/IP and Winsock settings to defaults, which resolves connection failures caused by corrupted stack data.
Reinstall Intel Wi-Fi Driver
Device Manager → Network adapters → Intel Wi-Fi 6 AX201 → Uninstall device. Download the Intel Wi-Fi driver from Dell Support for Latitude 3440 using your service tag. Install and restart.
Update BIOS via Dell Command Update
Open Dell Command Update and install any available BIOS update for the Latitude 3440. BIOS updates sometimes include Wi-Fi adapter power management fixes that resolve connection failures.
“Forgetting the network profile and running the netsh winsock reset command fixed the Wi-Fi on my Dell Latitude 3440 without a driver reinstall.” — Mohd Asyraf, Kota Kinabalu
