Security Mode
When the “Network Mode” is set to “Client (Infrastructure)” mode, this sets the security type
that the module will use to attempt to connect to the existing network. This will be beneficial
when attempting to connect to certain secured networks that the older firmware was having
issues in properly detecting the security type.
Use DHCP (recommended)
When the “Client (Infrastructure)” mode is active, the “Use DHCP” will cause the module to
try and obtain an IP address automatically when it connects to an existing network.
NOTE:
Having this box checked may make the module difficult to locate on an existing
network unless the existing network has been configured to always assign the same IP
address to the WIFI module.
When set to connect to an existing network, it is recommended to use static IP addressing
to make connecting to the module easier.
Once all settings have been entered, click “Save & Reboot” at the bottom of the webpage to
save the parameters.
NOTE: It is very important not to press “Enter” before all of the configuration
settings have been properly entered. Pressing “Enter” before entering in all of
the appropriate settings will submit the information and may put the device
into a state where it cannot be connected to. If this happens, it may be
necessary to isolate the 190-WIFI module from wireless signals and use the
DEFAULT jumper to restore the network to a known configuration.
Wi-Fi Operation
A connection to the 190-WIFI option card can be used to send commands to the 190.
A description of the available commands is described in the ASCII Commands section.
