1. Check the router

The first step is to ensure that you are within the wireless router range and things are correct on this end.

Open Settings on your iPhone and tap Wi-Fi. Make sure you are connected to the right network. A blue tick before the name signifies that you are connected. After this, tap on ‘i‘ next to the correct joined Wi-Fi name and turn on the toggle for Auto-Join.

Note: Sometimes, instead of the actual network (home, office, etc.), your device may automatically join an open, non-working network that you might have accidentally or intentionally connected in the past. To address this, tap on ‘i‘ next to this Wi-Fi name and turn off the toggle for Auto-Join.

Finally, and most importantly, restart the Wi-Fi router. This is one of the easiest, surest, and quickest ways to fix this issue. You may use the main switch or the power button on the router to turn it off and back on after a minute.

2. Turn off Wi-Fi and reconnect

  1. Open Settings on your iPhone and tap Wi-Fi.
  2. Turn off the toggle for Wi-Fi.

  4. Let your iPhone connect to the known network. Or, if needed, tap on the Wi-Fi name to join it. Enter the Wi-Fi password, if asked.

3. Enable and disable Airplane mode

  1. Bring up the Control Center: On an iPhone with Face ID, swipe down from the screen’s top right. On models with the Home button, swipe up from the bottom of the screen.
  2. Tap the airplane icon to enable it.

Restarting involves turning off the device and then switching it back on. You can use the physical buttons like usual or follow our guide on restarting your iPhone.

  1. Unfortunately all the mentioned methods does not give a permanent remedy.
    After switching from Dynamic IP to static IP the problem vanished immediately, connection speed up and latency reduced dramatically. Since non of my other devices (Linux and Window notebooks, Smart TV and Android Cellphone) face a similar problem it look like a bug – see my post
