Synology DS218+ (I’ll call it NAS) has been working fine for over a year connected to my home network (192.168.1.x) and not available outside my home.
A couple days ago, I was prompted to update to the latest DSM. I did. Afterwards, NAS no longer appears on my network no in the SynologyAssistant.
If I direct connect ethernet cable from computer to NAS, I can see the device. Drives and data are healthy, but I can’t change/apply settings to IP Configuration. I’ve tried setting it to DHCP, so it will take an IP number from the router. I’ve tried setting a static number on my 192 network. Neither seems to stick. Of course, when I apply changes to IP, I lose my direct connection, have to restart NAS, but it never seems to save the 192.
I would appreciate any advice?
========================
UPDATED WITH SOLUTION:
According to Synology Support, something about the updated DSM affected my device’s network configuration. Even though I could direct connect to the NAS, I was unable to reset the network settings.
Specifically, even though my NAS was configured to use DHCP to pull an IP address from my router, it was not working.
Per Synology’s instructions, I used a paperclip to reset the NAS. This “first-level reset” erases the admin password and resets the network configuration. After that, I rebooted and the NAS grabbed an IP number from my router. I then reset my admin password.
The first-level reset does not affect the volumes/data on the NAS. So, it was a bit scary, but no loss.
Thanks for all the ideas and support.
