    This is a great project. The 0.1 release is infinitely better than the factory's own. I was quite close to discarding my DNS-321, because even the latest factory firmware was never stable. Thanks to Alt-F (and all those who contribute to it), the box has a new lease on life.

    After "updating" to the latest and what seems like the final firmware from DLink (after years of not upgrading), all manners of problems resembling a first beta software occured. Can't say that isn't typical of DLink. Loved the hardware, always tortured by DLink's horrible software and support. In my search for solutions, I came upon mentions of Alt-F. A quick search and a few wiki entries later, it seems like a low risk solution to try: easy to install, easy to revert. So I downloaded and installed. At the moment of boot, the light turned purple instead of the jarring blue. I know this is something that's done with attention to detail (and how did they do that?). I'm only minutes into using the firmware, and already it's a breath of fresh air! Faster UI, faster transfers, no hiccups (yet, even being beta). I can finally finish my RAID setup, which kept on getting stuck and lose networking (crashed? who knows) with Dlink's own 1.10. Moving on to more important things, like actually backing up to the drive and feeling safer about it than DLink's own firmware. Thank you! Thank you! Thank you! For delivering us from the clutches of DLink's incompetence. Please keep this going. The DNS323 maybe an oldie, but it sure has a lot of life left in it, especially after Alt-F.

    Folks : a warm thank you to João Cardoso for this initiative. I have a DNS-320L-rev-A1 box and I upgraded yesterday from 0.1RC4 to experimental 0.1RC4.1.1 and the result is simply extra. It works fine (follow the readme) and fix all kind of troubles (fan cooler, shutdown ...) I was facing since July 14 with 0.1RC4. The best alternative if you want to go beyond poor D-Link original features Thanks again and happy new year 2015
