Interesting. I take it from your comment that you WERE having slow connections when there was more than one client. If you got a bump in speed, that's enough motivation for me to update, not that I am having speed problems to begin with. I wasn't having CAPTCHA problems so I was ho-hum about the update but then, my motto has always been "If it ain't boke, break it so you can fix it, then break it again". This is the only way I've ever learned anything about computers, routers etc. etc. I get very motivated when I screw something up and that motivation leads to other discoveries. ok, not on topic.
Haha, well it seems the update has corrected a few bugs from the previous build. I hear ya, that is the same way with me, you can only learn when something breaks, and then you have to fix it. In my case, it was just frustrating having the router choking from at least 4 connected wireless clients within my network. Obviously this never occurred when the first beta was not installed, it happened right after. Now it seems there has to be more to this updated beta firmware then we already know. Dlink is not disclosing what really was fixed, which is somewhat odd. Either way, this current firmware has worked miracles for me and now I don't need to have thoughts on putting a hammer to this router haha

By the way, what is "CAPTCHA"? Is it "Enable Graphical Authentication"
