Soon after February 22, 2022, without a firmware upgrade, select AirLink RV55/LX40/LX60 LTE routers will cease to connect to the AT&T network due to the AT&T network changes.

Select AirLink RV55/LX40/LX60 LTE routers will require an ALEOS update prior to February 22, 2022 or these routers will go off air and will require a site visit to restore connectivity.

AirLink LTE routers that require an ALEOS upgrade are:

We will provide a new ALEOS release in Q4 2021 that addresses the AT&T network configuration change that must be deployed on the impacted RV55/LX40/LX60 LTE router variants prior to February 22, 2022.

We will provide an update on the availability of the new ALEOS release by October 1, 2021.

New ALEOS firmware for the impacted RV55/LX40/LX60 LTE routers will be available on ALMS/AMM and the Source in Q4 2021. Beginning in Q4 2021, all newly manufactured AirLink LX40/60/RV55 routers will ship from the factory with upgraded ALEOS firmware and will not need a field upgrade.
