ready NAS rnd2110 - User Group Account issues

So I have an old Ready Nas Duo that I still use.  I don't access it often to realize that something happened in the past year and I am not sure quite why.  I apologize if I write a book.  I just want to provide the correct info for someone here to help me troubleshoot.

I have a Macbook pro BTW

So the summary of my issue is that I can't access the group accounts that are set up with data of them.  (Pic1) It almost looks like a DOS command prompt now vs. a folder.  

I can get into my shared folders.  I can get into my shared ip netgear address and my admin ip netgear adress to view my dashboards. 

So things that have changed this past year or possible issues that I am not sure how to solve or if they are related.  Changed from netgear router with the settings that worked on that to a comacast combo modem/router (latest highspeed one).  

From the Finder on Mac, looking at the NAS, it won't allow me to connect to anything but guest. I tried as a registered user.  I never had an issue before.  I think I used the name as the name of the Group list I atatched and a simple password that I always remebered.  

Initially when I double click on the command like prompt, it initially made a comment about the login shell being zsh vs. bash.  From upgrading Mac version, It gave me a page for instructions to change this.  I thought I did.  Nothing changed.  (Not sure if this is an issue).

The data is on the groups.  I can see them

I can provide any other info needed to help

Thanks
