What is Roaming? Roaming occurs when a wireless client device moves outside the usable range of one router or access point (AP) and connects to another router or access point. The client device automatically roams from one router (or access point) to another as needed to provide seamless connectivity.
How Roaming Works:
Roaming is a client decision. The wireless client is responsible for deciding it needs to roam, and then detecting, evaluating, and roaming to another AP.WiFi standards bodies (IEEE802.11/WiFi Alliance) do not specify when and how a client should roam. it is totally decided by your wireless client’s roaming algorithm. Different wireless client vendors’ use their own algorithm for roaming process but they are not generally published.

- Lowest: Your wireless client will roam when link quality degrade significantly.
- Medium-Low/Medium-High: these are normal roaming sensitivities, when your signal quality degrades around 50% the clients tries to roam to another route or AP.
- Medium: Balanced setting between not roaming and performance.
- Highest: Your Wi-Fi client continuously tracks the link quality. If any degradation occurs, it tries to find and roam to a better router or AP.
