I really want to thank you again. I have spent hours on this problem, but it looks like it is working, and your advice was perfect, just not easy to accomplish. So after I was directly connected to drobo5N with my MacBook Pro I was able to finally get the Dashboard open and update the firmware to 3.5.16 and then another update, version 4.2.1 which was also successful. I finally was able to open tools/network only to find it had an error and couldn’t load previous settings. But by following the Drobo Online User Guide “Adding a Drobo Device by ITs IP address”, opened Dashboard preferences then drobo discovery settings and finally found he IP address and how to set DHCP or connect manually using an IP address. I chose DHCP “enable auto discovery”
The final test was to connect the drobo5N back to the Eero hub and WOW, it works.
This was not easy. It took me an over an hour on the phone with Eero to try everything until they finally agreed to set the drobo to IPv6. I must have restarted my Mac at least 10 times since restarting the Dashboard didn’t work without restarting the MAc. And I kept losing the DAshboard’s connection to the drobo even when it was connected to my Mac.
I do have to add that Drobo made all this more difficult by having wrong update info on their website. I wasted time trying to find the correct versions. I even sent in a support request, but I’m still waiting for a response.
Downloads - Drobo shows Drobo Dashboard 3.0.1 for Mac for drobo5N which should be 3.5.2
And 3.5.12 Firmware when it should be 3.5.16
I’m giving details of what I did to help the next person who might have this problem.
