I have been a reader for a long time as you can see my account. I am not those fly-by posters.
I often checked station-drivers for latest drivers because the manufacturers don't update them very often. I don't know how but the guys at station-drivers.com can obtain the latest stuff when many of them are not even released yet.
Station-drivers often is down, therefore I post a mirror link at media-fire.
I guess D-Link not releasing it because it may not be tested extensively, but we are all beta testers here aren't we?
Obviously, it's your choice, however using software from an unknown source has it's dangers - ranging from simply bricking the hardware to compromising your network, data integrity and potentially identity theft.
I have long campaigned against this practise - and a few years back, after one post on the dangers, I offered - in the same thread - a hacked version of the DNS-323 firmware, describing it as a new beta release and was startled at the amount of requests.
With relatively small pieces of code, a NIC driver for example, it's not that easy to get creative, but, the DNS-323 firmware is large (>7MB for 1.07) and is an entire linux operating system - it's easy to slip a remote access trojan in there.
As you can see, there is a bit more risk than just a bad beta - but at the end of the day - it's your choice, it's your data, it's your identity
