I just noticed that my there's a firmware update available for one of my wireless routers I use at home to support WPA2. I haven't delved into WPA2 so far, but may now give it a chance if I'm feeling brave. I'm always nervous when it comes to applying firmware or BIOS updates after having a power outage a year or so ago during the course of flashing a motherboard BIOS. Needless to say, it died never to run again. It was an old-ish computer though, so gave me a good reason to upgrade :-).
Note that to support WPA2 on Windows XP SP2, you'll need an update documented in KB 893357. Now, what do I need to do to make this run on my Windows Server 2003 SP1 laptop......? I downloaded the fix but setup bombed with "The updatebr.inf file is invalid".
