What is the purpose of a wireless client sending a reassociation request to an AP?
- to find the SSID of the AP
- to form a new association with the AP
- to roam from current AP to another AP
- to respond to the beacon signal sent by the AP
Explanation & Hint:
When a client wants to join the BSS of an AP, it actively scans channels and sends probe requests to discover candidate APs. The client then selects one and tries to associate with it. A wireless client can send association request and reassociation request frames to the AP selected. Association requests are used to form a new association, while reassociation requests are used to roam from one AP to another, preserving the original association status of the client. |
