If you are already using Wi-Fi, sit near to the router or try switching the network on and off to ensure the signals are strong enough. Disconnect both, your device and PC/Mac from the Internet and reconnect them after taking a short break of 5-10 minutes. If you are still not sure about the network, try using another, if there is an option available for you to do so.

Clean your device by deleting all unused files and uninstall random applications that you seldom use or need. You can begin with erasing cookies, caches, browser search history, and log.
