Hooray! My problems are finally solved.
I used to be getting dropped connections with WPN824v2 by itself. No matter what I tried did not make much difference (that is, having windows or the built-in laptop device control the wireless connection, etc, etc.)
Bang, I decided to shell out some 80 bucks & get the WPN111 (108 Mbps Wireless USB 2.0 Adapter), and I've gotten steady 54Mbps connection all afternoon.
By the way, this is NOT intended to be some type of advertising for Netgear as I am somewhat pissed that Netgear didn't configure the WPN824 to be fully compatible with other manufacturors' built-in adaptors -- in my case, the Intel PROSet Wireless device that came with my laptop. They clearly could have done this, and in my humble opinion this must have been a deliberate decision in order to sell their adaptors.
Nevertheless, I thought it would be worthwhile to pass this on for the frustrated users out there.
