Windows can't connect to this network

How to Fix “Windows can't connect to this network”

Windows Network Error 📄 Windows 10, Windows 11
⚡ Quick answer

"Windows can't connect to this network" appears when Windows fails to join a Wi-Fi network — usually because of a corrupted network profile, wrong password, driver issue, or incompatible security settings.

First, check if your internet is working and what your current IP address is:

What Causes the “Windows can't connect to this network” Error?

Windows stores a profile for each Wi-Fi network it has connected to. If that profile becomes corrupted (after a router setting change, Windows update, or driver issue), Windows can't use it to authenticate. The error also appears if the network changed its password, security type (WPA2 → WPA3), or if the network adapter driver has a bug.

How to Fix It — 5 Methods

1 Forget and Reconnect to the Network

This is the first fix to try and resolves the majority of cases. Go to Settings → Network & Internet → Wi-Fi → Manage known networks → find your network → click Forget. Then reconnect from scratch: click the Wi-Fi icon in the taskbar, select your network, enter the password. This discards the corrupted profile and creates a fresh one.

2 Flush DNS and Reset Network

Open Command Prompt as administrator and run in order:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /flushdns
ipconfig /renew
Restart your computer. These commands reset your entire network stack.

3 Update or Reinstall Wi-Fi Adapter Driver

Open Device Manager (right-click Start) → Network Adapters → right-click your Wi-Fi adapter → Update driver. If updating doesn't help, try: right-click → Uninstall device (check "Delete the driver software") → restart Windows. Windows will automatically reinstall a clean driver.

4 Change Network Security Type

If your router recently switched from WPA2 to WPA3 (or vice versa), Windows may struggle. Log into your router admin panel and try setting security to WPA2/WPA3 mixed mode or WPA2 only. Also check that the router isn't using an incompatible channel width for your adapter (try setting to Auto).

5 Disable IPv6 and Reset TCP/IP

Go to your network adapter properties → uncheck "Internet Protocol Version 6 (TCP/IPv6)" → OK. Then in Command Prompt as administrator: netsh int tcp set heuristics disabled and netsh int tcp set global autotuninglevel=disabled. Restart.

Some errors are caused by ISP blocks or network restrictions
A VPN bypasses them instantly by routing through a different server.

Frequently Asked Questions

The password is correct but I still can't connect — why?
If the password is definitely right, the issue is the network profile. Forget the network and reconnect from scratch (Fix 1). If that fails, try the driver reinstall (Fix 3).
I can connect to other Wi-Fi networks but not this specific one — what's wrong?
The problem is the stored profile for that specific network or the router's MAC address filter. Forget the network and reconnect. Also check if the router has MAC filtering enabled — add your device's MAC address to the allowed list.
After a Windows update I can't connect to Wi-Fi — what happened?
Windows updates sometimes break Wi-Fi adapter drivers. Roll back the driver: Device Manager → Network Adapters → right-click adapter → Properties → Driver tab → Roll Back Driver. If Roll Back is greyed out, download the driver directly from your laptop or network card manufacturer's website.
