Issued By:
Sierra Wireless AirLink® Product Management
Products Affected:
AirLink® ALEOS Routers:
- LX40, LX60, RV50X, RV55, MP70
For Distribution To:
AirLink® Customers & Channel Partners
We have identified an issue where routers running ALEOS 4.17.0 will stop communicating with ALMS either for extended periods of time or permanently.
- This issue only affects ALMS communications.
- All other router functions operate normally e.g. passing cellular traffic, etc.
- Routers communicating with our AirLink® Mobility Manager (AMM) or our AirLink® Manager (AM) services are not affected by this issue.
- This issue will be addressed in ALEOS 4.17.1 to be released in early February 2024.
- Immediate action is required to mitigate the issue and is described below. These actions are recommended for both current and future users of ALMS.
Affected router symptoms:
- Up to 90 days after upgrading your router to ALEOS 4.17.0, ALMS will indicate that the router is no longer reporting into ALMS.
- Routers powered continuously for at least 18 hours, will automatically reestablish communications with ALMS after 18 hours.
- Routers powered for less than 18 hours continuously will not automatically reestablish communications with ALMS.
Actions for routers running ALEOS 4.17.0 that are continuously powered:
- These actions apply to routers that are continuously powered o e.g. asset monitoring, internet connectivity, etc.
- These routers will stop communicating with ALMS for approximately 18 hours every 90 days.
- Do not upgrade additional routers to ALEOS 4.17.0.
- Following the release of ALEOS 4.17.1, all routers should be upgraded to ALEOS 4.17.1.
- If the 18-hour ALMS communication loss every 90 days presents an operational concern, customers may downgrade
- ALEOS (to ALEOS 4.16.0 for LX40/60, RV50X & ALEOS 4.16.2 for RV55, MP70), and perform the ALEOS 4.16 security mitigations described in SWI-PSA-2023-006. (Contact support for any questions regarding security mitigations.)
Actions for routers running ALEOS 4.17.0 that are powered on and off regularly:
- These actions apply to routers that are used in vehicles or where the router is powered on and off regularly, where the router will not be in continuous operation for a least 18 hours. o e.g. utility vehicles, police vehicles, remote monitoring sites with periodic operation, etc.
- These routers will stop communicating with ALMS up to 90 days after the upgrade to ALEOS 4.17.1 and will not resume communications automatically.
- Do not upgrade additional routers to ALEOS 4.17.0 or deploy new routers with ALEOS 4.17.0.
- For routers running ALEOS 4.17.0 and still communicating with ALMS, immediately downgrade these routers (to ALEOS 4.16.0 for LX40/60, RV50X & ALEOS 4.16.2 for RV55, MP70) and perform the ALEOS 4.16 security mitigations described in SWIPSA-2023-006. (Contact support for any questions regarding security mitigations.)
- For routers no longer communicating with ALMS, upgrade to ALEOS 4.17.1 using ACEmanager when the release is available.
- Alternatively, to restore ALMS communications prior to the 4.17.1 release, downgrade these routers via ACEmanager (to ALEOS 4.16.0 for LX40/60, RV50X & ALEOS 4.16.2 for RV55, MP70) and perform the ALEOS 4.16 security mitigations described in SWI-PSA-2023-006. (Contact support for any questions regarding security mitigations.)
