Solving Problem with Wi-Fi Disconnection on iPhone or iPad

The problem of periodic loss of a Wi-Fi connection on the iOS device is not very common.

For example, if the office has its own network and a network of colleagues or at home and its neighbors’ routers. Sometimes user can face with weak WiFi signal (we already covered how to boost it here).

A smartphone can lose its connection for a moment with the main router and then quickly connect to the next one. And in view of the fact that it is further away, the signal may be worse and the Wi-Fi Assist function will turn on.

Wi-Fi Assist works as follows: when the iOS unexpectedly loses the Wi-Fi network, data is sent over the mobile connection. The system has a certain algorithm, which can include switching to a mobile connection if a bad Wi-Fi signal detected. A bit slowed down, a ping grew or in the distant rooms a bad signal detected, and the iPhone is already starting to download data via LTE.
