Note: The WWAN LED indicates a physical connection state between the ICX35-HWC and the cell
tower. It is not an indicator of a logical connection state. There may be a situation when you may see a
“Disconnect, will retry” indicator on the ICX35-HWC webpage, even when the WWAN LED light is on
(solid green). This indicates that the module was able to make a physical connection to the tower, but
the logical connection was not made between the ICX35-HWC and the cellular provider.
