How to Fix Wi-Fi Not Working on Windows 10

Restore internet access with fast, high-success diagnostic steps.

Last verified: February 21, 2026

Windows has a dedicated built-in internet troubleshooter that automates the most common Wi-Fi diagnostic steps — it's worth running before attempting manual fixes because it can identify adapter driver issues, DHCP lease failures, and corrupted TCP/IP stacks without any technical knowledge required. Windows 11 surfaces this at Settings > System > Troubleshoot > Other Troubleshooters > Internet Connections, while Windows 10 has it at Settings > Update & Security > Troubleshoot. The most powerful manual fix for persistent problems is the three-command network stack reset using netsh and ipconfig in an elevated Command Prompt.

Quick Steps

Follow in order for the fastest result.

  1. 1Toggle Wi-Fi off, wait 10 seconds, and turn it back on from Quick Settings.
  2. 2Restart your router and modem: unplug from power for 30 seconds, reconnect, and wait 2 minutes for it to fully restart.
  3. 3Go to Settings > System > Troubleshoot > Other troubleshooters > Internet Connections and run the automated fix.

Frequently Asked Questions

Why does my Windows 10 keep disconnecting from Wi-Fi?
Common causes: power management turning off the Wi-Fi adapter, driver issues, or IP address conflicts. Go to Device Manager > Network Adapters > right-click your Wi-Fi adapter > Properties > Power Management > uncheck Allow the computer to turn off this device to save power.
How do I know if the Wi-Fi problem is my device or my router?
Test another device on the same network. If that device also has no internet, the problem is the router or ISP. If the other device works fine, the problem is your specific device. This single test narrows the diagnosis immediately.
Why does my Windows 10 show connected to Wi-Fi but has no internet?
Connected but no internet means your device reached the router but the router can't reach the internet, or there's a DNS/IP conflict. Restart the router first. If that doesn't help, follow the Fix Wi-Fi Connected but No Internet guide for your device.
Why can my Windows 10 see Wi-Fi networks but not connect to mine?
This typically indicates a password mismatch, a MAC address filter on the router blocking the device, or the router assigning all available DHCP leases. Try forgetting the network and reconnecting with the exact password. If you have a MAC filter enabled on the router, add your device's MAC address to the allowed list.
