Windows Wi-Fi Not Connecting: 8 Fixes for "Can't Connect to This Network"

Last updated: January 15, 2026

Windows Wi-Fi issues fall into a few distinct categories: the dreaded "Can't connect to this network" error (a corrupted saved profile), "No internet access" while connected (a router or DNS problem), the Wi-Fi icon missing entirely from the taskbar (a disabled adapter), or Wi-Fi dropping every few minutes (a power management issue). Each has a specific fix — here's how to identify and solve yours.

Which error are you getting?

  • "Can't connect to this network" — corrupted saved profile. Go to Fix 1.
  • "No internet access" / yellow triangle — connected to router but router has no internet. Go to Fix 2.
  • Wi-Fi icon missing from taskbar — adapter disabled or driver issue. Go to Fix 5.
  • Wi-Fi keeps dropping every few minutes — power management throttling. Go to Fix 6.
  • Broke after a Windows Update — driver rollback needed. Go to Fix 7.

Fix 1: Forget the Network and Reconnect (Fixes "Can't Connect to This Network")

The "Can't connect to this network" error is almost always a corrupted saved network profile — Windows is trying to use stale security settings or a wrong password. The fix is to delete the saved profile and start fresh.

  1. Go to Settings > Network & Internet > Wi-Fi.
  2. Click Manage known networks.
  3. Find the network giving the error and click Forget.
  4. Click the Wi-Fi icon in the taskbar, select your network, and enter the password again.

If you don't know your Wi-Fi password, check the back or bottom of your router — it's usually printed there. Alternatively, on a device that's already connected (like your phone), look in the Wi-Fi settings for a "Share" or QR code option.

Fix 2: Restart Your Router and Run TCP/IP Reset Commands

"No internet access" while connected to Wi-Fi means Windows reached your router but your router can't reach the internet. First check if other devices (phone, tablet) on the same network also have no internet. If they do, the problem is your router or ISP — restart the router by unplugging it for 30 seconds. If only your Windows PC is affected, the problem is local network configuration.

Open Command Prompt as Administrator (search "cmd" in the Start menu, right-click, select "Run as administrator"), then run these commands one by one:

  1. netsh winsock reset — fixes corrupted socket entries
  2. netsh int ip reset — rebuilds IP configuration
  3. ipconfig /release — releases your current IP address
  4. ipconfig /renew — requests a fresh IP from the router
  5. ipconfig /flushdns — clears stale DNS cache

Restart your PC after running all five commands. This fixes most "connected but no internet" issues on Windows.

Fix 3: Change Your DNS Servers

If you can connect to Wi-Fi but some websites won't load or load slowly, your ISP's DNS servers may be having issues. Switching to Google or Cloudflare's DNS servers is fast, free, and often speeds up browsing significantly.

  1. Go to Settings > Network & Internet > Wi-Fi, then click your connected network name.
  2. Under "DNS server assignment," click Edit.
  3. Change from Automatic to Manual.
  4. Enable IPv4 and enter: Preferred DNS 8.8.8.8, Alternate DNS 8.8.4.4 (Google), or Preferred 1.1.1.1, Alternate 1.0.0.1 (Cloudflare).
  5. Click Save.

Fix 4: Run the Windows Network Troubleshooter

Windows has a built-in diagnostic tool that catches and automatically fixes several common Wi-Fi issues — it's worth running before going deeper.

  1. Go to Settings > System > Troubleshoot > Other troubleshooters.
  2. Find Network and Internet and click Run.
  3. Follow the prompts. Windows will test your adapter, check for IP conflicts, and attempt automatic repairs.

On Windows 10, the path is Settings > Update & Security > Troubleshoot > Additional troubleshooters > Internet Connections.

Fix 5: Enable Your Wi-Fi Adapter (Fixes Missing Wi-Fi Icon)

If the Wi-Fi icon is gone from your taskbar, or you can't see any Wi-Fi networks, the adapter may be disabled — either through Device Manager or a physical key on your laptop.

  1. Press Win + X and select Device Manager.
  2. Expand Network Adapters.
  3. Look for your wireless adapter (names vary — Intel Wireless, Realtek Wi-Fi, Qualcomm Atheros, etc.).
  4. If there's a down arrow on the adapter icon, it's disabled. Right-click it and select Enable device.
  5. Also check for a physical Wi-Fi key on your laptop keyboard — often labeled with a wireless icon and accessed via Fn + F2 or similar key.

Fix 6: Disable Wi-Fi Power Management (Fixes Dropping Wi-Fi)

If Windows keeps disconnecting from Wi-Fi every few minutes, especially when the screen is idle, power management is turning off the wireless adapter to save battery. This is a known Windows "feature" that causes a lot of frustration.

  1. Open Device Manager (Win+X > Device Manager).
  2. Expand Network Adapters and double-click your Wi-Fi adapter.
  3. Go to the Power Management tab.
  4. Uncheck "Allow the computer to turn off this device to save power".
  5. Click OK and restart.

Also go to Control Panel > Power Options > Change plan settings > Change advanced power settings > Wireless Adapter Settings > Power Saving Mode and set it to Maximum Performance.

Fix 7: Update or Roll Back Wi-Fi Drivers

Outdated drivers cause connection failures. But sometimes a new driver that Windows Update pushed is actually worse than the previous one. You can do both.

To update:

  1. In Device Manager, right-click your Wi-Fi adapter and select Update driver.
  2. Choose "Search automatically" — if Windows finds a newer driver, let it install.
  3. Better yet, visit your laptop manufacturer's website (Dell, HP, Lenovo, ASUS) and download the latest Wi-Fi driver for your specific model.

To roll back after a bad update:

  1. In Device Manager, right-click your Wi-Fi adapter > Properties.
  2. Go to the Driver tab.
  3. If Roll Back Driver is available (not greyed out), click it. This restores the previous driver version.

Fix 8: Reset Network Settings (Last Resort)

If nothing else has worked, a full network reset reinstalls all network adapters and resets all network components. You'll lose saved Wi-Fi passwords, VPN settings, and custom firewall rules, so be prepared to reconfigure those.

  1. Go to Settings > Network & Internet.
  2. Scroll to the bottom and click Advanced network settings.
  3. Click Network reset, then click Reset now.
  4. Your PC will restart automatically. After restart, reconnect to your Wi-Fi network.

On Windows 10, this is at Settings > Network & Internet > Status > Network reset.

What NOT to Do

Common mistakes that make this worse
  • Don't delete your network adapter drivers without a backup plan. Uninstalling Wi-Fi drivers without having an ethernet connection or a driver backup means you may be unable to reconnect to the internet to redownload them. Only remove drivers if you have an alternative connection method.
  • Don't run Windows Network Diagnostics expecting a complete fix. The built-in network troubleshooter diagnoses and fixes basic issues (IP conflicts, DNS problems), but it cannot fix corrupted driver files, router configuration issues, or ISP outages. Use it as a starting point, not a complete solution.
  • Don't connect to open public Wi-Fi to test if 'Windows' is the problem. Open networks behave differently than secured WPA2/3 networks and don't require the same authentication flow. A successful open Wi-Fi connection doesn't prove your Windows Wi-Fi stack is working correctly.
  • Don't reset your entire network stack (netsh winsock reset) for a basic connection problem. A Winsock reset fixes deep TCP/IP corruption but also resets firewall rules and proxy settings, which can break other network applications. Try targeted fixes first — IP renewal, DNS flush, adapter disable/enable.

Frequently Asked Questions

Q: What does "Can't connect to this network" mean on Windows?

A: This error means Windows has a corrupted saved profile for that Wi-Fi network. The stored password, security settings, or IP configuration no longer matches what the router expects. Fix it by forgetting the network (Settings > Network & Internet > Wi-Fi > Manage Known Networks > Forget) and reconnecting fresh.

Q: Why does Windows show "No Internet Access" even though Wi-Fi is connected?

A: A yellow triangle means Windows connected to your router but the router can't reach the internet. Try restarting your router. If other devices are fine and only your PC is affected, run the five TCP/IP reset commands in Command Prompt as Administrator (netsh winsock reset, netsh int ip reset, ipconfig /release, /renew, /flushdns).

Q: The Wi-Fi icon is missing from my Windows taskbar — how do I get it back?

A: Check if your Wi-Fi adapter is disabled: open Device Manager (Win+X), expand Network Adapters, right-click your wireless adapter, and select Enable Device. Also check for a physical Wi-Fi toggle key on your laptop keyboard (often Fn+F2).

Q: Why does my Windows PC keep dropping Wi-Fi every few minutes?

A: Windows Power Management is turning off the adapter to save power. Fix it in Device Manager: right-click your Wi-Fi adapter > Properties > Power Management tab > uncheck "Allow the computer to turn off this device to save power." Also set Wireless Adapter Settings to Maximum Performance in Power Options.

Q: What do the TCP/IP reset commands actually do?

A: netsh winsock reset fixes the Winsock catalog which handles socket communications. netsh int ip reset rebuilds IP configuration entries. ipconfig /release and /renew request a fresh IP address from your router. ipconfig /flushdns clears cached DNS entries. Together they clean up most software-level network issues without affecting your files or settings.

Still not connecting?

If you've tried all 8 fixes and Wi-Fi still doesn't work, the Wi-Fi adapter hardware may be failing — this is especially common on older laptops. A USB Wi-Fi adapter (around $15-20) is a quick workaround that bypasses the built-in adapter entirely. If this is a new PC under warranty, contact the manufacturer for a hardware replacement.
