WiFi Keeps Disconnecting or Won’t Connect

Most WiFi issues are software or driver related — not your router or ISP. Try these steps first.

1. Forget and Reconnect to the Network

Sometimes the saved WiFi profile gets corrupted.

  1. Click the WiFi icon in the taskbar
  2. Right-click your network name → Forget
  3. Click the network again and re-enter the password
  4. Check if it stays connected

2. Restart the Network Stack

This clears DNS and IP configuration issues.

  1. Open Command Prompt as Administrator (search “cmd” → right-click → Run as administrator)
  2. Run these commands one by one:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /flushdns
ipconfig /renew
  1. Restart your PC after running all commands

3. Update or Roll Back the WiFi Driver

A bad driver update is a very common cause of sudden disconnections.

  1. Press Win + X → Device Manager
  2. Expand Network adapters
  3. Right-click your WiFi adapter → Update driver
  4. Choose Search automatically

If it just started after a Windows Update, try right-click → Properties → Driver tab → Roll Back Driver instead.

4. Disable WiFi Power Saving

Windows sometimes turns off WiFi to save battery, causing disconnections.

  1. Open Device Manager → Network adapters
  2. Right-click your WiFi adapter → Properties
  3. Go to Power Management tab
  4. Uncheck Allow the computer to turn off this device to save power
  5. Click OK

5. Check the Router

If multiple devices are having issues:

  • Restart your router (unplug for 30 seconds, plug back in)
  • Make sure your device isn’t too far from the router
  • Try connecting to the 2.4GHz band instead of 5GHz — it has better range

Still disconnecting?

If none of these work, it could be a faulty WiFi card or a deeper driver conflict. Bring it in and we’ll diagnose it properly.
