1. General
The WLAN option allows the scale to be operated just as if it is connected to your network
via a cable. The only difference is the setting of the network parameters. Please have the
configuration settings of your WLAN infrastructure at hand.
1.1. Modifying WLAN option settings
WLAN option settings take place at the operating system level. After startup, the scale
runs either the Startup Wizard (in the case of starting up the scale for the first time) or the
scale application:
In the case of an entirely WLAN connection, set the primary network adapter to "
Wistron"

WLAN signal strength
indicates the signal quality. Note this is the signal quality of an
associated access point. The scale should therefore be configured for
WLAN settings
in
advance.

Alternatively - the console for purists:
Opening a shell and running the script ‘2root’ causes the required authorisation requests to
appear (the script ‘2root’ has a double password request, because the user changes from
‘scale’ via ‘scaleadm’ to ‘root.’):
Please request the preset password from a service technician.

The relevant LAN/WLAN settings are made by running the OpenSuSE setup tool (yast2):
Note:
yast2 is only supplied with the required modules and not with the full extent to which some
users are accustomed

You can adjust the size of the dialog box by dragging its upper left corner with the mouse.
The dialog box can thus be conveniently centred on the menu bar.
The WLAN adapter appears as ‘Wistron NeWeb CM9 Wireless a/b/g MiniPCI’ and its
typical WLAN settings are configured using the menu option ‘Configure.’ After entering the
suitable settings for your infrastructure (‘Next’->‚Next’->‚Finish’), your settings are activated
and yast2 closes automatically.
It is best practice to now reboot the network and perform an initial test.
/etc/init/network restart
ping known_IP_address
If the test fails, check the settings once more (ensure the WLAN adapter uses the ‘ath5k’
kernel module).
Some DHCP servers only assign a lease after a device has been restarted, if settings
have been changed, therefore restarting via 'Reboot' is also an option...
