Android won't connect to Wi-Fi

• Estimated time: 3 min

• Low risk

Use the observed state to choose a test without resetting networks.

1. On some devices this is Connections > Wi-Fi. Confirm Wi-Fi is enabled, the exact network name and the message shown when attempting to connect once.

   1. Settings
   2. ›Network & internet
   3. ›Internet

2. If the network is missing, follow visibility. If it rejects the password or never reaches connected, follow credentials. If it says connected without Internet, follow access: the Wi-Fi indicator does not guarantee Internet access.

1. Move near the router and check whether another device sees the same name. If neither sees it, check power and Wi-Fi broadcasting with the router administrator; retyping a password for an absent network will not help.

2. If another device sees it, test whether the phone sees another known compatible network. If it sees others, ask the administrator about this particular network; use another already configured band only if available and authorized. Do not weaken router security as a test.

3. For a hidden network, manually add only the name and security type confirmed by its administrator. If the phone sees no known nearby networks, restart it once after saving work; if unchanged, contact the manufacturer with that comparison.

1. Confirm the current name and password with the owner through a secure channel. Do not publish passwords or screenshots containing access details. An authentication message alone does not prove a typo: network policy can also prevent joining.

2. Try another known permitted network. If it joins there, focus on the first network’s profile or policy. If it fails on several compatible networks with confirmed credentials, restart the phone once and contact its manufacturer if it persists, rather than modifying every router.

3. At school or work, certificates, identity and authentication method must come from IT. Do not choose not to validate certificates or remove managed profiles. On a previously working personal network whose password or configuration changed, renewing only that profile is the next bounded test.

1. Temporarily turn off mobile data during this check so it cannot mask Wi-Fi without Internet access; restore your setting afterward. Open two known pages. If only one fails, investigate that site; if both fail, compare another device on the same network.

2. If all fail, check service and router status with its owner. On your home router, a power restart according to its manual can test a temporary hang; warn others because it disconnects sessions and do not use the factory-reset button. If Internet does not return, escalate to the provider.

3. If only Android fails, check whether the network requires a legitimate sign-in portal and whether the same phone works on another network. Do not ignore certificate warnings or enter credentials into unexpected portals. With a managed VPN or profile, take the result to IT before disabling it.
