What is an Access Point (AP)?

In an Enterprise Wireless LAN (WLAN) environment that supports roaming, a client associates to an AP based on a variety of parameters. These parameters include signal strength, speed, channel, error rate, and so on. After a client associates with an AP, there's a process by which it determines when to transition to the next AP.

Typically, when a client can no longer maintain a good connection with the current AP, it transitions to an AP that has better signal quality to ensure optimal bandwidth. This transition is called aggressive roaming. The clients running the Intel Unite® app must switch to the Access Point that provides the best signal because it's a real-time application.

AP stickiness refers to a WLAN client choosing to remain connected to one AP until the signal strength or bandwidth drop to a level that impacts its performance.

What is the challenge?

It's challenging to find an acceptable balance between switching between APs quickly and retaining the connection for a longer time. Intel WLAN driver version 18.40 provides this balance of AP stickiness and roaming.

How to fix it

If you experience lag in the display when connected to Intel Unite® app because of moving around in a meeting space, update the Intel WLAN drivers to version 18.40 or later to minimize the AP stickiness.
