Alt-F is an unbloated, fast and clean firmware offering almost everything I am possibly looking for. Web-UI is simple, yet light - and you can access all option regarding the system and the most important options regarding the packages. Explenations on the web-ui are very good. Support is awesome. Buttom line: I'm very grateful for the ffp-project, but Alt-F works so much better for me right now. It gets so much out of the cheap dlink devices. I'm using my DNS-320L besides storage as a media-chain (sickbeard, couchpotato). My previous setup was dlink+ffp+optware. It always felt like a 3-headed hydra, all interfering with each other. It was able to do the job, but always felt ugly and slower than necessary. Alt-F 0.1RC4 now offers "alpha" support for the DNS-320L. Even in this early stage I'm so much more happy than before. Feature-wishlist is - more complete configuration of packages in the web-ui for example for transmission, minidlna (for now shell is fine) - dropbox/ google drive/ whatever your poison - plex server?! Some might be optimistic. So much looking forward to further development.
Alt-F is fantastic! Gave new life to my DNS-320L. I recommend everyone (since read the instructions before use!)
I flashed this alternative firmware on my aging DNS-323 a long time ago. It has served me very well. Joao, who's responsible for this wonderful project is extremely helpful with all the questions and suggestions I had. I can't recommend this enough to breath new life in a product long forsaken by D-Link. After seeing regwergrgwerg's negative review, I had to add this note: There's absolutely no way flashing this alternative firmware will delete or in any way alter the data you already have on your drives. I feel sorry for regwergrgwerg if he lost data, but I am certain this is a result of his action(s), not the firmware's fault.
Alt-F is the best thing that can happen to your dlink DNS-323! Offers way more functions and flexibility compared to the stock firmware - which is not updated that often. True, that you should have some knowledge about what you do, but if you are not a complete idiot there is only marginal chance that you mess up anything. Also the project owner Joao is a great guy. He really offers some unparalleled support. I have never seen something like this - not even for a paid support. You can also flash the original firmware back if you'd like - but you won't :) Go for it!
