Change hostname in modem.

There was a similar post that has been closed.  The solutions offered do not work for me.  I can change the name on the xFi app but that doesn't change in the modem.  The hostname in the modem is the MAC address.  The device is an Iomega NAS.  It is using DHCP to obtain its address.  When I list connected devices and edit the device I can only enter a comment or change the IP address from DHCP to static.  When I connect in to the iomega it has its name as iomega-01b526.

From my PC I can map a drive to \\iomega\folder.  I can also ping iomega and get a return from the iomega's IP.  From Windows, when I expand my network to view all devices on the net, I don't see the iomega, but do see my dlink NAS.  Looking for any suggestions.
