If you still cannot see the specific share you are trying to access, open the Web Configurator and 
go to Network Setting > File Sharing. Make sure that the share has a check below the symbol

If the share’s settings have been set to Private, you may not have permission to see the share’s 
content. Open the Web Configurator and make sure you add your user to the list Allow Users in
