RT-N56R DLNA on 2 USB drives

[FinbarUTM]

Tried searching the forum, but couldn't find anything that answered my specific issue.

Just bought this router for the USB3 ports as my RT-AC66U was giving me some speed issues among other problems.

Have 2 3TB Seagate drives that are attached to the router through USB.

upgraded firmware to 3.0.0.4.374_4561 so now get Media Server working, but from the basic interface can only get one drive available at a time. Both are available through SAMBA shares.

I have already worked around using a PC based DLNA server, would like to take the PC out of the equation..

Any suggestions to get both drives available on the DLNA Media Server.

Thanks

Simon
