Hi, I want to connect network and get data by using Sixfab 4G/LTE Cellular Modem Kit for NVIDIA Jetson Nano DevKit. But device is not connected to cellular network. Device Status is OK but Cellular Status is NOT. ![Screenshot from 2023-11-02 15-23-37](https://community.sixfab.com/uploads/default/original/2X/a/a05b6b236f30a1dae19554641986ad5066373967.png) ![Screenshot from 2023-11-02 16-56-40](https://community.sixfab.com/uploads/default/original/2X/4/48d60ff6c7bcde546f0cffb4a52f1f860a187db2.png) ---

Hi, Could you please enable the remote support and PM me your remote-support token so I can check and fix it? Additionally, I will request you to send the _ICCID_. ---

Hello @ensar & @a.dangac , Was this issue resolved? I have similar issue with one of my Jetson nano LTE boards. The cellular connection will be active for a few minutes after reboot of the nano but goes offline after that. ![Screenshot from 2024-01-18 10-26-05](https://community.sixfab.com/uploads/default/original/2X/9/98d7e25c86c0c00986d1b3772ae52d37c6373312.png) ---

Hi @nkamidi , Did you get any errors when you ran your installation code? Which OS version are you using? Can you confirm if there are any problems with your WiFi connection? Can you share the status of core\_agent service? ---

Hello @ensar , There were no errors during the installation. This Jetson Orin Nano is running Jetpack 5.1.2 (Ubuntu 20.04). Please see the saved outputs below. I also downloaded the core-manager and core-agent logs. I can share those if necessary. **Note:** I would like to highlight is that first I installed core agent without the suffix " -b Jetson -d" but later on reinstalled by adding this parameter. Not sure if that makes a difference. ```auto ===================================================== [INFO] Sixfab user already exists, updating... [INFO] Updating sudoers...
