A Windows 10 PC can connect to the Internet through Wi-Fi or Ethernet. Start with the normal network controls rather than changing IP settings, disabling the firewall, or resetting the entire network. Windows 10 reached the end of standard support on October 14, 2025, so a connected Windows 10 computer also needs a Windows 11 migration or applicable Extended Security Updates plan.
Connect through Wi-Fi
- Select the network icon on the taskbar.
- Turn on Wi-Fi if it is disabled.
- Select the name of your wireless network.
- Choose Connect and enter the Wi-Fi password when prompted.
- Open a trusted website to confirm that Internet access works.
Connect with Ethernet
Connect an Ethernet cable between the PC and a router, switch, or other appropriate network connection. Windows normally configures the connection automatically through DHCP. If the network icon still reports no Internet access, test the cable and router port before entering manual IP addresses.
If the PC connects to Wi-Fi but has no Internet
Check another device on the same network. If every device is offline, restart the modem/router according to the provider’s instructions or check the ISP for an outage. If only the PC is affected, restart Windows, forget and reconnect to the Wi-Fi network, and check Windows’ network troubleshooter or adapter status.
Avoid weakening security during troubleshooting
Do not permanently disable Microsoft Defender Firewall just to make the Internet work. A firewall problem should be diagnosed as a specific blocked application, profile, or rule. On a work or school network, proxy, VPN, certificate, or administrator settings may also control connectivity.
If the network requires a browser sign-in page, as in some hotels or public hotspots, open a browser after connecting and complete the provider’s legitimate captive-portal process. Never enter sensitive credentials into a certificate-warning page.
Before resetting the network adapter, note any VPN or organization-specific configuration that may need to be restored afterward.
