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. DNSSEC Queries Support: The support for DNSSEC queries was added and router now enables LAN devices to query DNS records protected by cryptographic signatures.
2. IP Address Ranges Support: The support for IPv4 and IPv6 address ranges has been added to Firewall settings, allowing the Source or Destination address to be in format 192.168.1.100-192.168.1.200.
3. Updated List Behavior: Several lists now hide unused items and support a larger number of entries. Initially, only two items are shown, but as the last item is filled, two more will automatically become visible.
4. Updated WiFi AP Configuration: Configuration now prevents invalid parameter combinations from being displayed. Only valid options are now selectable. To see the correct list, the Country Code must already be applied.
5. Removed 802.1X Option From WiFi AP Configuration: The 802.1X option has been removed from the WiFi AP configuration because it was misleadingly named and enforced WEP encryption with static keys, which is highly insecure. The 802.1X protocol is still supported in combination with WPA encryption under the WPA-Enterprise options.
6. Fixed Cellular Modem Failures: Previously, the cellular modem could restart under heavy load (when downloading large files), causing transmission failures.
7. Fixed WiFi Issues: This update resolves multiple WiFi issues, including authentication problems with WPA3-PSK on ICR-2xxxW routers (notably with Ubiquiti UniFi 6 Lite) and firmware reboots when connecting to 5 GHz WiFi APs.
Availability
The new firmware can be downloaded directly to the router from Advantech's public server, or manually from the Firmware or Router Models pages. For specific firmware versions and compatibility details, please refer to the Firmware Compatibility Chart document.
