How to Fix Windows 11 Can't Connect to This Network Error

The Problem

You select your network, enter the password, and Windows immediately returns Can't connect to this network—often before it has had time to attempt authentication. A wrong password is only one possibility. Stale saved profiles, WPA3-only routers, and broken drivers all produce the same unhelpful message.

It connects but keeps dropping? See Wi-Fi keeps disconnecting. This guide is for when joining fails outright.

Symptoms

  • Connection fails within a second or two, with no "incorrect password" prompt.
  • The same network works on a phone; only this PC refuses.
  • It started after a router change, a Windows update, or a driver install.
  • Other networks—a phone hotspot, for example—connect normally.

Step 1: Forget and Rejoin

Windows caches a network profile including the security type. When the router changes, the stale profile no longer matches and Windows fails instantly rather than adapting.

  1. Settings → Network & internet → Wi-Fi → Manage known networks.
  2. Select the network → Forget.
  3. Turn Wi-Fi off, wait ten seconds, turn it back on.
  4. Select the network and re-enter the password carefully—watch for Caps Lock and for a router that has both a 2.4 GHz and 5 GHz SSID with different passwords.

This alone fixes a large share of cases, and it is the first thing to try after any router change.

Step 2: Power-Cycle Both Ends

  1. Unplug the router for 30 seconds and let it fully restart.
  2. On the PC choose Restart, not Shut down—Fast Startup restores the same broken adapter state on a shutdown.

A stale DHCP lease causes instant rejections on some mesh systems, and a router reboot clears it.

Step 3: Check the Router's Security Mode

Windows adapters vary in what they accept, and a mismatch produces this exact error.

In the router's wireless settings:

  • For testing, set WPA2-PSK (AES). Avoid WPA/WPA2 mixed with TKIP, which older Windows drivers handle badly.
  • If the router is WPA3-only, either update the Wi-Fi driver from Intel, Realtek, or Qualcomm, or switch the router to WPA2/WPA3 transitional so older adapters can join.
  • Check the channel width and band. Some adapters fail on 160 MHz channels or on DFS channels in the 5 GHz band—setting 80 MHz and a non-DFS channel is a good test.
  • Confirm MAC address filtering is off, or that this PC's MAC is on the allow list. Note that Windows 11 uses random hardware addresses by default, which breaks MAC filtering—turn that off per-network in Wi-Fi → the network → Random hardware addresses.

Step 4: Reset the Adapter

  1. Device Manager → Network adapters → right-click the Wi-Fi adapter → Disable device → wait ten seconds → Enable device.
  2. Still failing? Uninstall device, tick Attempt to remove the driver only if you have a replacement ready, then restart.
  3. Install the driver from your laptop or motherboard maker rather than a generic package. On Intel adapters, install the full Wi-Fi package, not just what Windows Update offers.

Also open Properties → Power Management and untick Allow the computer to turn off this device to save power.

Step 5: Reset the Network Stack

In Terminal (Admin):

netsh winsock reset

netsh int ip reset

ipconfig /flushdns

Restart before testing.

To clear every stored profile at once:

netsh wlan delete profile name=* i=*

That forces a clean rejoin to every network, which is a heavier version of Step 1.

Step 6: Full Network Reset

Settings → Network & internet → Advanced network settings → Network reset → Reset now.

This removes and reinstalls every network adapter and restores default settings. You will lose saved VPN profiles and Wi-Fi passwords, so export anything you need first. Restart, then rejoin.

Special Cases

  • Hidden SSID: Manage known networks → Add network → type the exact name and security type. Also tick Connect even if this network is not broadcasting.
  • Corporate or university Wi-Fi: enterprise networks need a certificate or a configuration profile from IT. None of the home fixes apply, and repeated failed attempts may lock the account.
  • USB Wi-Fi dongle: move it to a rear motherboard port, away from USB 3.0 devices, which interfere with 2.4 GHz.
  • After a Windows feature update: check Device Manager for a driver Windows replaced with a generic one, and reinstall the vendor's.

Isolating the Fault in One Test

Create a simple WPA2 hotspot on your phone and try to join it.

  • PC joins the hotspot → the adapter and driver are fine, and the problem is your router's configuration or band settings.
  • PC fails there too → the adapter, driver, or Windows networking stack is at fault. Steps 4 to 6 are where the fix lives.
