Just wanted to share my experience here hoping that will help preventing the same issue happening to someone else. So I’ve moved into another condo recently and I took my previously immaculately working WD My Cloud. I have always used it with FTP access therefore operating with static IP address. It was locally fixed at 192.168.1.150 on a D-link DIR-650 wireless router. When I moved to the new place the internet service provider provided an upgraded model of D-link DIR-816L Dual band wireless router. I was super happy so the time came to hook up my WD MyCloud to the network. To my surprise it didn’t work and I was completely lost what to do. I didn’t see it on the network at all and my numerous attempts to access the dashboard on 192.168.1.150 proved to be useless. Then I sat back for a second and checked the new router default DHCP gateway. It was a bit different: 192.168.0.1 instead of the previous 192.168.1.1. I suspected that the problem is somewhere here as MyCloud is trying on 1 instead of the 0 gateway.
The solution at the end was that luckily I still had the old DIR-650 so I hooked that up, connected the MyCloud and finally I was able to access the dashboard. There I immediately set the network settings back to DHCP insted of Static IP. It came back with an error message at the end but that was no problem. Once I hooked it to the new DIR-816L I could set it up like a dream. No issues at all.
So as a conclusion if you plan on moving/relocating or even changing your router make sure you set the Network settings on your MyCloud back to DHCP before you make that move. That will save a lot of headache for you. I hope this helps.
