Wireless Settings
try setting the fragment size to send smaller fragments. This will speed up the
retransmission of smaller frames. However, it is more efficient to set the fragment
size larger if very little or no interference is present because it requires overhead
to send multiple frames. (Range: 256-2346 bytes; Default: 2346 bytes)
Wireless Security
The Pocket VoIP Gateway's wireless interface is configured by default as an "open
system," which broadcasts a beacon signal including the configured SSID. Wireless
clients with a configured SSID of "ANY" can read the SSID from the beacon, and
automatically set their SSID to allow immediate connection to the wireless network.
To improve wireless network security, you have to implement two main functions:
• Authentication – It must be verified that clients attempting to connect to the network
are authorized users.
• Traffic Encryption – Data passing between the unit and clients must be protected
from interception and evesdropping.
For a more secure network, the access point can implement one or a combination of
the following security mechanisms:
• Wired Equivalent Privacy (WEP)
• IEEE 802.1X
• Wi-Fi Protected Access (WPA) or WPA2
The security mechanisms that may be employed depend on the level of security
required, the network and management resources available, and the software
support provided on wireless clients.
