Currently, Amazon Alexa Devices aren't supported on letnet. This is due to Amazon not allowing WPA2-Enterprise as a secure Wifi mechanism for these devices. We have learned from Amazon that WPA2-Enterprise will be available sometime second quarter of 2018.
Amazon has a new Alexa for Business framework that we are experimenting with. It is very new (as of the creation of this article) but shows promise for integrating Alexa into LETU's infrastructure.
If you are interested in using an Amazon Alexa for LETU business purposes, please contact us.
