How do I use Android as a WiFi repeater?

Creating a Wi-Fi hotspot has become a popular way of sharing your mobile data connection with others. But what if you wanted to share your Wi-Fi connection (the one to which your phone is already connected) with other devices and effectively extend your Wi-Fi coverage? In this article, we take a look at the various ways in which you can use your smartphone as a Wi-Fi repeater/Wi-Fi extender


Without pointing out what smartphone you mean to use as an Wi-Fi repeater and which Android version it has, i cannot answer your question completely.

But lets get to atleast a working solution, without the needing to install an app. I tested it on my Samsung Galaxy Note 8 (using Android 9, with SIM card inserted) and it works. Its not precisely a dedicated Wi-Fi extender, but you can make it work close enough to one, if the setup is proper.

  • Turn on Wi-Fi and connect to an Access Point.
  • Go to Settings -> Connections -> Mobile Hotspot and Tethering -> Mobile Hotspot.
  • Turn on “Wi-Fi sharing”.
  • Setup your Hotspot settings by clicking the vertically oriented three dots on the right and afterwards “Configure Mobile Hotspot”.
  • Turn the Mobile Hotspot on.
