We are glad to share the information that we developed new models within our ICR-4400 family to avoid the temporary unavailability of WIFI chips from the supplier. Those new models keep the same high-end WIFI parameters as the original models and the only drawback is a slightly decreased temperature range for the router reaching -40 to +60°C.  

The new router models are marked as ICR-4453W1 + ICR-4453W1S for 5G, ICR-4434W1 + ICR-4434W1S for 4GLTE-A, and ICR-4401W1 + ICR-4401W1S for wired routers (without cellular module on). All models marked as “W1” in the PN code containing the new 2.4/5GHz, 3 × 3 MIMO WIFI module are to be available at the end of March 2022. When original chips are to be available (expected end of 2022/start 2023) we expect switching back to “W” models only with an extended temperature range -40 to +75 °C.

Technical details are possible to find here in appropriate datasheets.
