Zyxel 310 doesn't answer ping/ssh after some time

Hi,

with the help of bodhi (thank you again) I installed uBoot 2017.7 and Linux Kernel 5.5.1 on my Zyxel 310. Everything seems to work fine when the box boots up. I was able to install some things and I was generally very satisfied with everything. But now I noticed that the NAS disappears from the network. It's like it isn't connected to the router at all.

The lights are on and it works fine when I restart it. Has anybody experienced this? And does anybody have an idea how to debug this situation?

Thank you for your help!

enp1s0 is the connection I am talking about. Is it possible that it disappears over time? Does it mean anything that the device is called enp1s0 instead of eth0?

I think it has something to do with systemd. You are running it with your bootargs.

set_bootargs=setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 $mtdparts init=/bin/systemd

It is the new naming scheme for network device enp1s0 is the same as eth0.

Try remove systemd init

fw_setenv set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 $mtdparts'

And run with sysvinit for a while to see if you have this problem again. Note that the system will assign eth0 again in sysvinit.

And then you can decide to switch back to systemd. If you do that, you need to upgrade to get the latest Debian packages to make sure you get rid of a few old systemd bugs.

Hi bodhi,

thank you for your reply. I will switch to sysvinit and hope it helps.
