...actually, Vista RC1 wouldn't play with it at all. My system: Dell Dimension XPS Generation 5/2x3.8Ghz Pentium 4/4Gb SDRAM @ 667Mhz/nVidia GeForce 6800 (256Mb memory)/2x250Gb HDDs in RAID 0/Intel 955x motherboard Used Windows Vista RC1 (Build 5600) The wireless adapter in question was the D-Link "RangeBooster" WUA 2340. The problem is that RC1 would not recognize and install the driver for the adapter. Now, looking at it from hindsight, I was attempting to install from my account (which was listed as an Administrator account) but not from THE named Administrator account. I don't know that that would have made a difference, though, as the problem seemed to be specific to the driver's .inf file itself: Unlike any other .inf file from among a small sampling, this driver wouldn't install through the context menu "Install" command. This is not an outdated piece of hardware, at least not that I'm aware of, but a search of D-Link's web site gives the impression that this manufacturer is somehow wholly unaware that Windows Vista even exists. Is there anything like a generic one-size-fits-all Microsoft-produced driver that might handle this? The one (internet-less) day I spent exploring RC1's updated feature set and responsiveness made me want to keep it, but with an online freelance writing business, I can't very well chop off my legs just for nicer shoes (to torture a metaphor.) :)
