MTU
Maximum Transmission Unit
The maximum data size that can be transferred at a time
through the Internet or other networks. You can set a
smaller MTU size to obtain successful communication,
if you have difficulty transferring data due to the fact
that the maximum size is too large.
Network authentication
The method of authentication performed by wireless
LAN clients to connect with the access point. There are
two types: open system authentication and shared key
authentication. The type of authentication must be set
to each client and also coincide with the setting of access
point with which to communicate. Network authentica-
tion is sometimes called authentication mode.
Network key
Data that is used for encrypting data in data communi-
cation. The personal computer uses the same network
key both for data encryption and decryption, therefore,
it is necessary to set the same network key as the other
side of communication.
Network name (SSID: Security Set Identifier)
When a wireless LAN network is configured, grouping is
performed to avoid interference or data theft. This
grouping is performed with “Network name (SSID)”. In
order to improve security, the network key is set
allowing no communication unless “Network name
(SSID)” coincides with the network key.
NTSC
National TV Standards Commission. The standard for
TV broadcast and reception for the USA.
Open system authentication
One of network authentication types for wireless LAN.
Since there is no check of network key upon authentica-
tion, clients can connect to the access point without
submitting correct network keys. However, in case of
actual communications, the same network key must be
set. Open system authentication is sometimes called
Open key authentication.
