3.5.2 Configuring Wireless Network Interfaces
The ANET1553 device offers support for an USB based Wi-Fi network device in order to
connect the ANET1553 to a wireless network.
From the time when the Wi-Fi USB device is attached to the USB port of the
ANET1553, the
Network Settings tab will show an additional section that allows
configuring the Wi-Fi device (See figure 3.1.4.2-1).
The checkbox ‘
Enable Interface
’
can be used to enable/disable the Wi-Fi device.
‘
Link Status’
section displays if the Wi-Fi device is currently connected to a wireless
access point (AP) and if it this, the quality of the link. Please note, that in Ad-Hoc mode
no link status is available, as no central connection to an AP is established.
‘
Available Networks’
section displays the wireless network in reach of the ANET1553
device.
The ‘
Address Configuration’
section can be used to assign an IP address to the Wi-Fi
device. Proceeding is the same as for the Ethernet interface device of the ANET1553.
At last, there are following Wi-Fi specific settings, which have to be configured:

Mode
: Set to ‘
Managed
’
if you want to connect to a network with a central
wireless access point. Use ‘
Ad-
Hoc’
(also called IBSS), if you want to join a
peer-to-peer network without central access point.

ESSID : This is the alphanumeric ID of the wireless network, the ANET1553
device shall connect to. In ‘
Managed
’ mode, the AP defines this ID. In ‘
Ad-
Hoc’
mode, all participants of the peer-to-peer network must agree on the
same ESSID.

Security : Wireless networks use different security methods to protect against
unauthorized access. Use
‘Unsecure’
if the network you want to join does not
use any security mechanism. Choose
‘WEP’
if the wireless network is
protected with Wired Equivalent Privacy (WEP). Last supported security
method of the ANET1553 device is Wi-Fi Protected Access II using a pre-
shared key, which can be configured by using ‘
WPA2-
PSK’
. Please note that
WPA is not supported in Ad-Hoc mode.

Password/Key: If the wireless network uses any of the security methods
mentioned above, except Unsecure , it is necessary to enter the password/key
for the network. In WEP mode, the key can be in ASCII (5 or 13 characters) or
Hexadecimal format (10 or 26 digits). WPA uses only passwords in ASCII
format which must contain at least 8 characters.
