All fixes in this guide
Fix: WiFi connected but no internet
This usually means your device is connected to the router, but the router cannot reach the internet, DNS is failing, or only this device has a bad network setting.
Fix: WiFi keeps dropping
WiFi usually drops because of weak signal, interference, router overload, overheating, outdated device software, or a buggy WiFi adapter driver.
Fix: WiFi says wrong password
Wrong password errors can happen even with the correct password if the saved network profile is corrupted, the router security mode changed, or the device does not support the router's WiFi settings.
Fix: WiFi network not showing up
A missing WiFi network usually means the router is off, hidden, too far away, using a band your device cannot see, or the device's WiFi is disabled or stuck.
Fix: WiFi not working on one device only
If every other device works, the router is probably fine. Focus on the one device's saved network, VPN, DNS, software update, or WiFi adapter.
Fix: One device cannot connect to WiFi
When only one device cannot connect, the usual causes are a saved bad password, incompatible security mode, blocked device, parental controls, or broken network settings.
Fix: WiFi is slow on one device only
Slow WiFi on one device is usually caused by weak signal, background downloads, VPN, old drivers, low-power mode, or that device choosing a crowded WiFi band.
FAQ
Why is my WiFi not working?
The most common causes are a router or modem glitch, weak signal, a bad saved network, VPN or DNS problems, an internet provider outage, or one device having broken network settings.
Should I restart my router first?
If multiple devices are affected, restarting the router and modem is a good first step. If only one device has the problem, start with that device instead.
Why does WiFi say connected but no internet?
It means your device is connected to the router, but the router may not be reaching the internet, DNS may be failing, or the device may have a bad network setting.
Why does WiFi work on some devices but not others?
If WiFi works on some devices, the router and internet connection are probably working. Focus on the failing device's saved network, VPN, DNS, software update, or WiFi adapter.
