If you don’t want your Apple device to automatically rejoin a network, you can make it forget that network.
Your Apple device remembers each Wi-Fi network that you joined on that device, and it automatically joins that network again whenever it’s in range. If you don’t want it to rejoin the network, or you want it to join with a different password, follow these steps to make your device forget that network and its password.
