Gentlemen,
DNS 323 is an old product that is not being actively worked upon. This seems so atleast from the non existent support and anaemic firmware upgrades.
I think we should all just start supporting the alt-f firmware. I am going to support him financially. Not a big amount, just a few bucks. This will give him more motivation to work on the alternative firmware for the DNS-323.
Alt-f has worked great for me. Transfer speeds are significantly higher too. With the Dlink firmware, I barely got about 10-11 MBps, when transferring from & to a Gbit desktop over LAN cable. With the Alt-f firmware I am able to hit 18-18.5 MBps, when moving the same files to the same desktop.
Also features like ability to connect USB hdd, UPnP & DLNA clients, Transmission, Samba & NFS make it a no brainer to switch. I agree some features are already available on the stock firmware, but the packages in the Alt-f firmware are newer versions and are updated more frequently.
My only major gripe with the Alt-f firmware is that the UI is ugly. But very functional. But I don't login very often. So its not a major con.
Disclaimer: I am not connected to the Alt-f firmware in anyway, but I am a happy user.
