Ensure that the Wi-Fi signal is strong and that your device has connected to the correct network.

Attempt to restart your modem and router by unplugging them both for 60 seconds and then plugging them back in.

Consider if there is any obstructions, such the walls, or other electronics between your devices and your wireless router.

Check for updates from your internet service provider for the router and modem.

Try connecting another device to the same Wi-Fi network to see if it experiences the same issue.
