Fix a Windows PC connected to Wi-Fi but with no internet | TP-Link Router
Troubleshoot Windows PC or laptop on TP-Link Wi-Fi with device checks, outage guidance, safe reconnection, and model-qualified router steps. Written for your Windows PC or laptop, with your TP-Link router in mind.

These steps are written for a Windows 10 or 11 PC or laptop. The router-side fixes apply to every device on your network.
Windows can show a wireless connection without an internet route. Compare another device first; do not disable security software as a shortcut. Repeat the same test.
Check the Internet/WAN status light or the TP-Link Tether app. Light patterns and router sign-in addresses vary by model; use the label or manual for your exact router.
Troubleshooting steps
Find out whether the device or network is affected
Wi-Fi alone does not prove internet access. Compare devices before changing settings.
Check provider status before equipment changes
For several affected devices, use the provider's official app, outage page, or phone support. If an outage is listed, wait for updates instead of repeatedly restarting equipment.
If no outage is reported and you manage the equipment, follow its restart instructions once: modem first, then router after modem startup. Do not press Reset.
Reconnect and check Windows PC or laptop
Open Settings > Network & internet > Wi-Fi and check the selected network. If only this PC fails, test trusted Wi-Fi elsewhere; a hotspot may use mobile data. Inspect Settings > Network & internet > Proxy only if you intentionally use one. Do not turn off a workplace proxy, firewall, or security control.
Use model-specific TP-Link guidance
Identify the model and hardware revision from its label, then use the matching manual. Tether availability and status screens differ by model; do not assume a login, light meaning, or feature.
Escalate safely and confirm the result
Avoid guessed DNS, IP, proxy, router security, or firmware changes. Update only when the provider or maker recommends it for the exact model and gives instructions.
Tell support the start time, number of devices affected, model and revision, exact error/status text, and tests tried. Never share passwords, verification codes, or payment details.
Retest the same site or app on the original device and, if possible, a second device. Repeat where the failure occurred and note whether access stays restored.
Frequently asked questions
Should I disable the Windows firewall?
No. Disabling protection is not a safe general fix. If the PC fails on several known-good networks, contact IT or Microsoft with the exact error.
Should I factory-reset TP-Link?
Not as an early fix. It can erase provider and household settings. Proceed only if the maker or provider directs it and can help restore service.
