|
Users can more easily roam from one WLAN to another.
|
|
|
The SSID can easily be discovered, even when it is not contained in beacon frames, because it still is transmitted in other management frames sent by the AP.
|
|
|
Turning off the SSID broadcast may prevent users from being able to freely roam from one AP coverage area to another.

Detailed explanation-1: -Ad-Hoc Node (Mesh) Some wireless devices (laptops, smart phones, or wireless routers) support a mode called Ad-Hoc. This allows those devices to connect together directly, without an Access Point in-between controlling the connection.
Detailed explanation-2: -How can filtering augment some of the security limitations of (WEP) in a (WLAN)? By defining parameters to which client stations must adhere in order to gain access to the network.
Detailed explanation-3: -WEP only supports 64-bit or 128-bit encryption key sizes, which can be more easily decrypted than the larger 256-bit encryption key. WEP is limited to the use of hexadecimal characters, which only allow for numbers 0–9 and the letters A–F. The key length is therefore not very secure.
