Hi JochumDeVries, the LTE3316-M604 have two different hardware and different firmware. Following call LTE3316 v1 and LTE3316 v2, the firmware naming: * LTE3316 v1 with firmware V1.00(ABMP.0)C0 * LTE3316 v2 with firmware V2.00(ABMP.0)C0 Your device uses FW V1.00(ABMP.2C)0, so it is LTE3316 v1. Please download…

Hi WelshPaul, not sure if you get NR5101 from your ISP. My suggestion is if you get the device from ISP, maybe ISP contact window could give you hand. If the device is from store, Zyxel local agent might help you.

Hi acastelli , you can enable SSH and Telnet on GUI>Maintenance>Remote Management page, then login SSH/Telnet via admin account(same username and password you login WebGUI) to execute the ZySH command.
