Fix No Internet After Windows 10 Update

If you have no internet after a Windows 10 update, the quickest fix is to restart your router and PC, then run the built-in network troubleshooter. If that fails, reset your network stack with the commands ipconfig /release, ipconfig /renew, and netsh winsock reset from an elevated Command Prompt. Below are the detailed steps, likely causes, and how to prevent it from happening again.

Why Updates Break Internet

Windows 10 updates often replace or update network drivers, TCP/IP stack settings, and firewall rules. A new driver may be incompatible with your Wi-Fi adapter or Ethernet chip, or the update may reset your network adapter’s power management settings. Sometimes the update leaves the network profile in a transitional state, causing the adapter to show “No internet” even though it is connected. The problem is more common after feature updates (like version 22H2) than after monthly cumulative patches.

First Steps: Restart and Troubleshoot

1. Restart your PC and your router/modem. Unplug the router for 30 seconds, plug it back in, and wait for it to fully boot.
2. Open Settings > Network & Internet > Status and click Network troubleshooter. This will run diagnostics and may automatically fix issues like a disabled adapter or wrong DNS.
3. If you use Wi-Fi, forget the network and reconnect: Settings > Network & Internet > Wi-Fi > Manage known networks, select your network, click Forget, then reconnect by entering the password again.
4. If you use Ethernet, unplug the cable, wait 10 seconds, and plug it back in.

Reset the Network Stack

If the above doesn’t work, the TCP/IP stack or Winsock catalog may be corrupted. Open Command Prompt as administrator (right-click Start > Command Prompt (Admin) or Windows PowerShell (Admin)) and run these commands in order:

1. ipconfig /release – releases your current IP address.
2. ipconfig /renew – requests a new IP address from the router.
3. netsh winsock reset – resets the Winsock catalog.
4. netsh int ip reset – resets the TCP/IP stack.

After each command, wait for it to finish. Then restart your PC. If the problem was a corrupted network configuration, this will likely fix it. Note that netsh int ip reset will reset your static IP and DNS settings to automatic, so you’ll need to reapply any manual configurations.

Update or Roll Back Network Drivers

A bad driver is a common culprit. To check, open Device Manager (right-click Start > Device Manager), expand Network adapters, and find your Wi-Fi or Ethernet adapter. Right-click it and select Update driver > Search automatically for drivers. If Windows says you already have the best driver, go to the manufacturer’s website (e.g., Intel, Realtek, Qualcomm) and download the latest driver for your exact model.

If the problem started right after the update, you can roll back the driver: in Device Manager, right-click the adapter, select Properties > Driver tab > Roll Back Driver. This option is only available if a previous driver existed. If it’s grayed out, you can download the previous driver from the manufacturer’s site.

Disable Power Saving on the Adapter

Windows 10 sometimes sets your network adapter to turn off to save power, which can cause the connection to drop or not reconnect after an update. To disable this:

1. Open Device Manager and find your network adapter.
2. Right-click it and select Properties.
3. Go to the Power Management tab and uncheck Allow the computer to turn off this device to save power.
4. Click OK and restart.

This is especially relevant for laptops, where power saving is more aggressive.

Flush DNS and Reset IP Helper Service

Sometimes the issue is DNS-related. Open Command Prompt as administrator and run:

• ipconfig /flushdns – clears the DNS cache.
• net stop iphlpsvc – stops the IP Helper service (which handles IPv6 transitions).
• net start iphlpsvc – restarts it.

If you use a VPN or proxy, disable it temporarily. Also check Settings > Network & Internet > Proxy and make sure “Use a proxy server” is off unless you actually use one.

When to Use System Restore or Uninstall the Update

If none of the above works, you can roll back the entire update. Go to Settings > Update & Security > Windows Update > View update history > Uninstall updates. Look for the most recent update (usually a KB number) and uninstall it. Restart and see if internet returns. If you prefer, use System Restore: type “Create a restore point” in the Start menu, click System Restore, and choose a restore point from before the update. This will revert system files and settings but not your personal files.

Frequently Asked Questions

Why does my Wi-Fi show “Connected, no internet” after an update?

This usually means your PC has a valid IP address but can’t reach the internet. It could be a DNS issue, a corrupted TCP/IP stack, or a firewall rule changed by the update. Try flushing DNS and resetting Winsock first, then check if your router’s DHCP is assigning a proper IP.

Can I prevent this from happening in the future?

You can pause updates temporarily, but the best prevention is to keep your network drivers updated manually from the manufacturer’s site, and set your network connection as a metered connection to control when updates install. However, metered connections may not receive all updates, which can be a security risk.

Is it safe to use the “netsh winsock reset” command?

Yes, it’s a standard troubleshooting command. It resets the Winsock catalog to its default state, which can fix connectivity issues. It doesn’t delete your files or settings, but it may reset some network-related configurations like firewall rules for certain apps. It’s safe to run.

What if I use a VPN and lose internet after updating Windows 10?

VPNs often use virtual adapters that can be disrupted by updates. First, uninstall the VPN software and restart, then reinstall the latest version. Also check that the VPN’s TAP adapter (or similar) is enabled in Device Manager. If the issue persists, run the network reset from Settings > Network & Internet > Status > Network reset, which will remove and reinstall all network adapters.

Will a network reset remove my Wi-Fi passwords?

Yes, the “Network reset” option in Windows 10 removes all saved Wi-Fi networks and passwords, along with VPN connections. You’ll need to reconnect to your Wi-Fi and re-enter passwords. It also resets your network adapters to defaults, which is why it’s a last resort.

Should I disable IPv6 to fix no internet after update?

Sometimes, but not always. If your router or ISP has issues with IPv6, disabling it can help. Go to Control Panel > Network and Sharing Center > Change adapter settings, right-click your adapter, select Properties, uncheck Internet Protocol Version 6 (TCP/IPv6), and click OK. This is a temporary workaround; if it fixes the issue, your router’s IPv6 configuration may need updating.
