Unidentified Network No Internet Access on Windows

Unidentified Network No Internet Access on Windows

Unidentified network - No internet access means Windows can see a connection, a cable or a Wi-Fi network, but couldn't get the details it needs from your router to use it. In most cases the PC never received an IP address. The fixes below work on Windows 11 and Windows 10 and go from quick to more thorough.

First: Is It Only This PC?

Check a phone or another computer on the same network.

• Other devices also have no internet: the problem is the router or your provider. See router connected but no internet.
• Only this PC is affected: carry on below.

Fix 1: Restart the Router and the PC

Unplug the router (and modem, if separate) for 30 seconds, plug it back in and wait until its lights settle, usually 2-3 minutes. Then restart the PC with Start > Power > Restart. This clears a stuck DHCP service on the router, which is the most common cause.

Fix 2: Check the Cable and Port (Ethernet)

• Unplug the cable at both ends and plug it back in firmly.
• Try a different port on the router and, if you have one, a different cable.
• If you use a USB-to-Ethernet adapter or a dock, plug it straight into the PC, not into a hub.

Fix 3: Check the IP Address

1. Right-click the Start button and choose Terminal or Command Prompt.
2. Run:

ipconfig

1. Look at the IPv4 Address of the adapter you use (Ethernet or Wireless LAN).

If it starts with 169.254, Windows gave itself an address because the router didn't answer. If it shows a normal address (often 192.168.x.x or 10.x.x.x) but still no internet, jump to Fix 6.

Fix 4: Renew the IP Address

In the same window, run these one at a time:

ipconfig /release
ipconfig /renew

/release briefly drops the connection; /renew asks the router for a new address. Run ipconfig again and check the address no longer starts with 169.254.

Fix 5: Make Sure the Adapter Uses Automatic (DHCP) Settings

A leftover manual IP address stops the router from assigning one.

1. Open Settings > Network & internet.
2. Choose Ethernet, or Wi-Fi and then your network's properties.
3. Next to IP assignment, click Edit and choose Automatic (DHCP).
4. Do the same for DNS server assignment unless you set a DNS server on purpose.

Fix 6: Reset TCP/IP and Winsock

Open Command Prompt as administrator (search for cmd, right-click it, choose Run as administrator) and run:

netsh winsock reset
netsh int ip reset
ipconfig /flushdns

Restart the PC afterwards. These commands put the network stack back to its default settings; they don't touch your files. If the address was fine but pages don't load, also see DNS server not responding.

Fix 7: Run the Network Troubleshooter

Open Settings > System > Troubleshoot > Other troubleshooters and run Network and Internet (on current Windows 11 builds it opens in the Get Help app). It checks the adapter and DHCP and can reset them for you.

Fix 8: Update, Roll Back or Reinstall the Network Driver

1. Right-click Start and choose Device Manager.
2. Expand Network adapters.
3. If the problem started after an update, right-click your adapter, choose Properties > Driver > Roll Back Driver.
4. Otherwise choose Uninstall device (leave the driver-deletion box unticked) and restart. Windows reinstalls it.

If it still fails, download the network driver for your exact model from the PC or motherboard maker's support page. Avoid driver-updater programs.

Fix 9: Turn Off VPN, Proxy and Third-Party Firewalls

Disconnect any VPN. Check Settings > Network & internet > Proxy and turn off Use a proxy server unless your workplace needs it. If you use a third-party firewall or security suite, pause it briefly to test, then turn it back on straight away.

Fix 10: Network Reset (Last Resort)

Open Settings > Network & internet > Advanced network settings > Network reset and click Reset now. The PC restarts, reinstalls all network adapters and clears saved Wi-Fi networks, so have your Wi-Fi password and any VPN details ready.

Still Not Fixed?

If the error only appears on Wi-Fi, see WiFi does not have a valid IP configuration, which covers the same DHCP problem from the Wi-Fi side. If the router gives addresses to every other device but never to this PC, even with a new cable, the network port or adapter may be faulty; a cheap USB Ethernet or Wi-Fi adapter is a quick way to confirm.
