Raspberry pi stops to work as a gateway

Hello, I´m working with modules DWM1001 to measure distances between tag-anchor. I use the raspberry pi 3 as gateway, but when I wrote commands ‘sudo apt-get upgrade’ and then ‘sudo reboot’ the raspberry stop to work as a gateway. Why would be this problem? How can I fix it?

Best regards.

Hi @laura.ece
my best guess is that the kernel gest updated and the dwm kernel module is not compatible with the new one. Fixing it is not easy - you can try to downgrade the kernel (Im not sure if it is possible) or just reflash the SD card with the provided RPi image.

Next time you need to block kernel update - see this post updates - How to I prevent Ubuntu from kernel version upgrade and notification? - Ask Ubuntu
