What is Reassociation Wi-Fi?
In WLAN network, reassociation request frame is used by mobile stations in the following scenarios: • Moving from one basic service area to the other service area in the same extended service area. • leaving the wifi network coverage area and comes back to the same area again.
What is the difference between association frames and reassociation frames?
association frames are management frames, whereas reassociation frames are control frames. Reassociation frames are used during the roaming process. The reassociation frame contains an additional field called the Current AP Address. This address is the BSSID of the original AP that the client is leaving.
What is Reassociation request?
Reassociation request frame – (0x02) A device sends a reassociation request when it drops from range of the currently associated AP and finds another AP with a stronger signal. The new AP coordinates the forwarding of any information that may still be contained in the buffer of the previous AP.

What is the advantage of SSID cloaking?
What is an advantage of SSID cloaking? It is the best way to secure a wireless network. Clients will have to manually identify the SSID to connect to the network. It provides free Internet access in public locations where knowing the SSID is of no concern.
What information does the association request contains?
The association request contains chosen encryption types if required and other compatible 802.11 capabilities. If an AP receives a frame from a mobile station that is authenticated but not yet associated, it will respond with a disassociation frame placing the mobile into an authenticated but unassociated state.

Is Wi-Fi a WLAN?
Wi-Fi networks are absolutely WLANs. But the important nuance is Wi-Fi is not the only type of WLAN. It’s safe to say Wi-Fi is pretty much the only WLAN these days that services human clients directly, although in-building cellular may qualify as well, while most other WLANs likely service headless client device nodes.
Should SSID be hidden?
The primary benefit of hiding your SSID is that it reduces the likelihood of an attack by keeping hackers and nosy neighbors from even knowing your network is there. It makes your network less of a “low hanging fruit” by making it more difficult to find.
