TOPEX BYTTON HSDPA
User’s Manual
pag. 32
Connection Mode:
It has two options, Infrastructure and Ad-Hoc.
Infrastructure
: default operation mode. Several WiFi clients can connect to the BYTTON HSDPA, acting
as server.
The “Infrastructure” mode takes full advantage of the AP's ability to cover wide areas.
Ad-Hoc
: two wireless clients interconnect directly, without the need for an AP. In this connection mode,
the BYTTON links directly to a computer with WiFi or an AP that is set to work in Ad-Hoc mode.
The “Ad Hoc” Mode is easier to set up, thus recommended for a very small or temporary
network.
This setting is related to the previous one - usually, the “Ad-Hoc” connection is used when Operating
Mode is set to “Station”.
Radio Channel
: Selects the WiFi channel in the 2400 MHz band.
In this band there are up to 14 channels, placed 5 MHz apart. Left on
“Auto” (default setting) and the AP will automatically select the radio
channel with the strongest signal. When selecting a certain channel,
make sure all devices are broadcasting on the same channel.
This setting may be left on default, and changed only when experiencing
interference with other devices.
WEP Security
: Enables or disables WEP (Wired Equivalent Privacy) encryption.
WEP encryption is used to protect data transmitted from one end point to another.
The encryption level (64-bit or 128-bit) is given by the
length of the WEP Key you enter.
If you enable WEP, these fields become active as
shown here:
WEP Key 1 … 4
: The data keys used for
encryption/decryption. There are up to four keys, their
values must be the same on the BYTTON Access
Point and on the wireless stations connected to it.
When using a 64-bit WEP encryption key, the
password must be 5 characters long, and when using
128-bit WEP encryption key the password must be 10
characters long.
WEP Key Index
: shows which key is active. You may have a list of pre-defined keys out of which the
system administrator periodically chooses the active one. The selected WEP key is automatically
published to the clients of the Access Point.
Warning
:
WEP is a basic encryption method and it was designed to provide a level of privacy equivalent
to an unsecured wired LAN, so you should not rely only on WEP for protection.
WPA sec
: WPA security
Wi-Fi Protected Access, a Wi-Fi standard designed to improve the security features of WEP. It features
improved data encryption through the temporal key integrity protocol (TKIP) and user authentication,
through the extensible authentication protocol (EAP). EAP is built on a secure public-key encryption
system to ensure that only authorized network users can access the WiFi network.
You can select to Disable the WPA security, or to use PSK or
PSK2 keys. PSK means "pre-shared keys": the keys are public,
every user is given the same passphrase.
