42 | Connectivity Troubleshooting
Cause
Wrong network name.
Network (SSID) is not
visible (Not being
broadcasted).
Network is not compatible
with the Thermo Fisher
802.11 AC network card.
UI firmware.
Wrong SSID and Password.
Network requires user
acceptance or input via a
web browser (like at a
hotel).
Weak Signal Strength
(RSSI).
MAC Address Filtering.
Solution
Verify the correct network name was provided.
Verify the network (SSID) is visible (being broadcasted)
using a mobile device.
*Thermo Fisher Devices are not able to connect to SSID's
that are not being broadcasted.
Verify with Local IT the network is compatible with the
Thermo Fisher 802.11 AC network card.
*Wireless 802.11 AC is compatible with 802.11 B, 
802.11 G, and 802.11 N.
*Freezers only support the 2.4GHz frequency. 5Ghz SSID
is not supported.
Contact service.
Verify you are connecting to the correct network (SSID) and
are entering the correct password. (Suggestion: attempt
the same network connection via an alternate device, like
a cell phone, laptop or tablet.).
Try restarting the freezer and re-attempt to establish the
Wi-Fi connection.
Verify wireless access is not dependent on accessing a
web page first.
*Freezer is not compatible with Wi-Fi networks that
require a login via web page, such as many "guest" or
"visitor" networks. Using such a network will cause the
Wi-Fi connection to fail.
Verify Signal Strength (RSSI) is at least -65 dBm or better
at the wireless interface of the device.
Verify with local IT if MAC address filtering is in place.
If MAC address filtering is in place, work with local IT to get
the device added to an approved list.
Navigate to Settings, Connectivity and Wi-Fi to see the
MAC address.
