Windows 11 Connects to Wi‑Fi but Has No Internet on Multiple Networks

If the resets don’t help, reinstall the wireless adapter driver. Open Device Manager, expand Network adapters, right-click the Wi‑Fi adapter, uninstall the device, and restart so Windows can reinstall it. You can also download the newest driver from the laptop manufacturer using another device. Network reset is worth trying before doing anything more drastic.

It could be a DNS problem. In Command Prompt, run `nslookup www.google.com`. If it times out or returns an error instead of an address, check whether a manual DNS server was configured. Removing an unknown manual DNS setting or switching temporarily to a reliable public DNS service may restore browsing.

Since the problem follows the laptop across different Wi‑Fi networks, the issue is probably with Windows’ network configuration rather than either router. Open Command Prompt as administrator and run `ipconfig /release`, `ipconfig /renew`, `ipconfig /flushdns`, `netsh winsock reset`, and `netsh int ip reset`. Restart afterward. If it still fails, check Settings > Network & internet > Proxy and make sure no manual proxy is enabled. Windows’ Network reset option under Advanced network settings is another useful last resort.

A full signal only means the laptop is connected to the router; it doesn’t guarantee that traffic is reaching the internet. If the laptop can’t browse at all, ignoring the warning won’t help. Since other devices work and there’s no VPN involved, focus on DNS, the Windows network stack, proxy settings, and the Wi‑Fi driver rather than changing router security settings.
