WiFi Roaming occurs when a smartphone , tablet or other wireless client device moves outside the usable range of a WiFi router and connects to another WiFi router. Roaming can also happen when the quality or strength of the client’s received signal drops. The client device automatically roams from one router to another as needed to provide seamless connectivity.
WiFi roaming refers to the ability of devices to automatically connect to another WiFi router (same networks name) without any user intervention. This allows users to maintain a continuous internet connection as they move from one area to another, ensuring they don’t lose access to their online activities.
Overall, WiFi roaming has become an essential feature for many modern users, allowing for greater flexibility and ease of access when it comes to staying connected to the internet while on the go.
First thing first , roaming is a client decision. The wireless client itself is responsible for detecting the need for roaming. In short, when the quality and strength of the received signal of the wireless client falls below a certain limit, it looks for a stronger router for connection. WiFi standards bodies (IEEE802.11/WiFi Alliance) do not specify when and how a client should roam.
It relies on a technology called Handover, which enables devices to detect and connect to nearby WiFi networks without any manual input. Handover mechanisms typically utilize protocols like Fast BSS Transition (FT) and Fast Dormancy to facilitate seamless transitions.

Click configure and you will see the following picture on the bottom. Choose Advanced and choose Roaming aggressiveness or Roaming sensitivity (based on your wireless network adapter brand).
Now , you can control the Wireless client device roaming behavior by choosing the proper item from right menu. As you can see below, there are items from lowest to highest sensitivity:
Unfortunately, there is no any specified configuration to control the smart phone roaming behavior, but you can use third party App’s for this purpose. for example, wifi roaming fix. you can simply set roaming sensitivity by changing the “Signal level” , -45 is a high , -65 is medium and -75 is low sensitivity levels.
