What is wifi roaming? Wifi roaming occurs when a wireless client device moves outside its access point (AP) and connects to another access point.
You can roam your wireless devices when traveling everywhere with a consistent connection. This roaming function is automatic when a client device transfers to connect with another router or access point.
How Does Wifi Roaming Work?

When these seamless access points far away from your home have the same configuration (SSID or network name) and credentials, your wifi will automatically roam to use another router or access point.
How does wifi roaming work?
The wifi roaming works as a wifi hotspot when you are on your way. What is a wifi hotspot? A physical access point allows Wi-Fi users to connect their portable devices to a router or Internet access from the Wi-Fi provider.
The roaming process includes three phases: scanning, authentication, and re-association.
Scanning occurs when the client devices send the probe packets to seek alternative access points. Your devices will choose another access point with a stronger signal to replace.
If client devices send an authenticating request to new access points, this process is authentication.
During waiting for new access points’ authentication, client devices send one more request. This process is re-association.
After completing this process, the new access points will send the disassociation packets to the old access point.
The former access point will stop connecting. Your devices will start another session with the new access point.
