Hello Lonnie,
When it fails what is the error seen on the device and ZD events and activities?
Do they work on open SSID on Ruckus?
if yes, please make sure that both Ruckus gear and First Data gear is running on latest code and TEST again.
By doing this we can find out whether it is some encryption/keying related issue or not.
I just had a quick peek into First Data FD100 doc at
www.firstdata.com/demos/terminal_demo...
this shows that it has more open security options on the device which you can try.
AND some best practice to follow from the doc:
You may also be able to obtain better performance by setting up
the Wi-Fi access point in some of the following ways:
•Set the Wi-Fi access point to use a non-default wireless channel
(such as 1, 6 or 11), and avoid any channel already being used by
any other Wi-Fi network within the same coverage area.
•If using more than one access point in the Wi-Fi network, ensure
that each access point is assigned a unique channel number.
• If the Wi-Fi access point has an option for “Auto Frequency,”
disable it.
• Set the b/g/n/mixed mode for the 802.11 (2.4 GHz range) to use
either g or n only, and not mixed if possible, depending upon
which terminals you have and what other devices are sharing the
access point. If all your devices support n, then use only n; but if
the devices only support different modes, then mixed is the only
option.
Best of luck
