Advantech is excited to announce the latest version of ICR-OS, the proprietary firmware for our cellular routers. This major release brings a range of new features and improvements aimed at enhancing both the functionality and security of our routers. All newly assembled routers will come with this firmware version pre-installed.
For a full breakdown of the advancements and changes in this release, we encourage you to review the official Release Notes.
1. WireGuard Tunnel Subnets Capacity: Increased the maximum number of Remote subnets in the WireGuard tunnel configuration from 4 to 32.
2. NTP Time Sync Error Resolved: Fixed failure of the Set Date and Time operation when invoked via Query NTP server in firmware 6.5.2.
3. General Status Page Modified: Modified System Information on the General Status page to display the Product Type by default and the Hardware UUID only when More Information is requested.
