Windows 11 Wi-Fi Shows Connected but No Internet After Resume: Fix

After resuming from sleep or hibernate, your Windows 11 laptop or desktop may show the Wi-Fi icon as connected but you cannot open websites, use email, or access network resources. This problem occurs because the network adapter fails to renegotiate a fresh IP address or DNS settings after the system wakes from a low-power state. The issue is not caused by a faulty router or ISP outage — it is a Windows power management conflict or a stale network stack. This article explains why this happens and provides six tested methods to restore internet access without restarting your computer.

Why Windows 11 Loses Internet After Resuming from Sleep

When your computer enters sleep mode, Windows 11 saves the current system state to RAM and cuts power to most hardware components, including the Wi-Fi adapter. The adapter is powered off or placed into a low-power state. When the system resumes, the adapter wakes up and reassociates with the Wi-Fi access point. However, the DHCP lease that was valid before sleep may have expired or the DNS cache may contain stale entries. Windows 11 does not always automatically request a new IP address or flush the DNS cache on resume. This leads to a scenario where the Wi-Fi connection appears active — the adapter reports a connected state — but the network stack cannot route traffic because the IP configuration is invalid or the DNS server is unreachable. Additionally, power management settings in Device Manager can cause the adapter to be disconnected entirely, requiring a manual reset.

The problem is most common on laptops and tablets that use power-saving features aggressively. Third-party antivirus software, VPN clients, or outdated Wi-Fi drivers can also interfere with the reconnection process. The solutions below address each root cause in order of simplicity.

Steps to Restore Internet After Resume on Windows 11

Try these methods in the order listed. Each method targets a different aspect of the network stack. Test internet access after each step before proceeding to the next.

Method 1: Run the Network Troubleshooter

1. Open Settings
   Press Win + I to open Settings. Click System in the left pane, then click Troubleshoot.
2. Select Other troubleshooters
   Click Other troubleshooters. Scroll to the Network and Internet section.
3. Run the troubleshooter
   Click the Run button next to Network Adapter. Follow the on-screen prompts. The troubleshooter will detect if the adapter is misconfigured and attempt to reset it.

Method 2: Release and Renew IP Address via Command Prompt

1. Open Command Prompt as administrator
   Press Win + R, type cmd, then press Ctrl + Shift + Enter. Click Yes in the User Account Control prompt.
2. Release the current IP address
   Type ipconfig /release and press Enter. Wait for the command to complete. This disconnects the adapter from the network.
3. Renew the IP address
   Type ipconfig /renew and press Enter. This requests a new IP address from the router. Wait 10–15 seconds.
4. Flush the DNS cache
   Type ipconfig /flushdns and press Enter. Close the Command Prompt window.

Method 3: Disable Power Saving for the Wi-Fi Adapter

1. Open Device Manager
   Right-click the Start button and select Device Manager.
2. Locate your Wi-Fi adapter
   Expand Network adapters. Look for an entry containing “Wi-Fi”, “Wireless”, or “WLAN”. Right-click it and select Properties.
3. Disable power saving
   Click the Power Management tab. Uncheck Allow the computer to turn off this device to save power. Click OK.
4. Restart the adapter
   In Device Manager, right-click the Wi-Fi adapter again and select Disable device. Wait 5 seconds, then right-click and select Enable device.

Method 4: Reset Network Stack with Netsh Commands

1. Open Command Prompt as administrator
   Press Win + R, type cmd, then press Ctrl + Shift + Enter.
2. Reset Winsock catalog
   Type netsh winsock reset and press Enter.
3. Reset TCP/IP stack
   Type netsh int ip reset and press Enter.
4. Restart your computer
   After both commands complete, restart your PC. This method is more thorough than the ipconfig commands and resolves persistent adapter state issues.

Method 5: Update or Roll Back Wi-Fi Driver

1. Open Device Manager
   Right-click Start and select Device Manager.
2. Update the driver
   Expand Network adapters, right-click your Wi-Fi adapter, and select Update driver. Choose Search automatically for drivers. If Windows finds a newer driver, install it.
3. Roll back if problem started after a recent update
   Right-click the adapter and select Properties. Click the Driver tab. If the Roll Back Driver button is available, click it and follow the prompts.

Method 6: Perform a Network Reset

1. Open Settings
   Press Win + I to open Settings.
2. Navigate to Network reset
   Click Network & Internet in the left pane. Scroll down and click Advanced network settings. Under More settings, click Network reset.
3. Reset now
   Click the Reset now button. Windows will warn that this will remove all network adapters and reset their settings. Click Yes. Your computer will restart automatically after 5 minutes. After reboot, reconnect to your Wi-Fi network.

If Wi-Fi Still Shows Connected but No Internet After Resume

If the main methods above do not resolve the problem, the issue may be caused by third-party software or specific router settings. Check the following scenarios.

VPN or Antivirus Firewall Blocks Traffic After Resume

Some VPN clients and antivirus suites with firewall components do not properly reinitialize after sleep. Temporarily disable the VPN or antivirus firewall. If internet access returns, reconfigure the software to allow network traffic on resume or update it to the latest version.

Router DHCP Lease Time Is Too Short

If your router is configured with a DHCP lease time of 1 hour or less, the lease may expire while the computer is asleep. Log into your router’s administration page and increase the DHCP lease time to 24 hours or more. This prevents the IP address from being reassigned to another device during sleep.

Wi-Fi Adapter Does Not Support Wake-on-LAN Properly

Some older Wi-Fi adapters have incomplete support for the Windows 11 power management model. In Device Manager, check the Advanced tab of your Wi-Fi adapter properties. Look for a setting named Wake on Magic Packet or Wake on Pattern Match. Disable these settings and restart your computer.

Wi-Fi Adapter Power Management Features: Sleep vs Hibernate Behavior

Item	Sleep Mode	Hibernate Mode
Power state of Wi-Fi adapter	Low power or off (D3)	Fully off (D3cold)
Adapter reconnection method	Reassociates with AP, may reuse old DHCP lease	Fresh DHCP request required
Typical fix needed	Disable power saving in Device Manager	Run ipconfig /renew or network reset
DNS cache behavior	Cache is preserved	Cache is cleared

After applying the fixes in this article, your Windows 11 computer should reliably regain internet access after every resume from sleep or hibernate. Start with the Command Prompt ipconfig commands — they fix the issue in most cases without any system changes. If the problem returns regularly, disable the power saving option for your Wi-Fi adapter in Device Manager. For persistent cases, a network reset clears all adapter settings and provides a clean baseline. As an advanced step, you can create a scheduled task that runs ipconfig /renew and ipconfig /flushdns automatically whenever the system resumes, using the Task Scheduler trigger On workstation unlock.
