Open Settings > Wi-Fi and verify a blue checkmark appears beside the intended network. Turn Airplane Mode off and note any No Internet Connection or privacy warning; do not confuse a cellular connection with working Wi-Fi.
2
Test whether the network or iPhone is responsible
Open a known website on another device connected to the same Wi-Fi. If no device has internet, restart the router if you manage it and contact the internet provider; resetting the iPhone will not repair an upstream outage.
3
Restart the iPhone
Use the normal power-off control for the model, wait for shutdown, then turn it on. Reconnect to the Wi-Fi network and test a fresh website rather than a page already cached in the browser.
4
Forget and rejoin the network
In Settings > Wi-Fi, tap the network's information button and choose Forget This Network. Confirm only after you know the Wi-Fi password, then select the network and enter the password again.
5
Check settings that can alter routing
Temporarily disable a VPN or third-party filtering service and verify Date & Time is set correctly. Restore each setting after testing; do not remove work or school management profiles without administrator approval.
6
Update the iPhone
On another working connection, back up the iPhone and check Settings > General > Software Update. Install a compatible update, reconnect to the affected network, and test again.
7
Compare another Wi-Fi network
Connect the iPhone to another trusted network. If only one network fails, focus on that router, access controls, or provider. If every network fails on this iPhone, continue with device-specific recovery.
8
Reset network settings as the last local step
Open Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This removes saved Wi-Fi passwords and resets cellular, VPN, and APN-related settings, so record required configurations first.
If the iPhone receives no address or the router rejects it, restart both devices and ask the network administrator to check access controls. If every trusted network still fails after the reset, preserve the iOS version and symptoms and contact Apple rather than erasing the phone.
