I've narrowed my problem down to this: I have the D-Link DIR-625-C router
set to "WPA Personal" - "WPA Only", My laptop with XP and a Linksys adaptor
prompt for a passphrase as should be, (and my iPod-Touch) but my sons PC
has Vista installed and a D-Link USB adaptor, It prompts for "additional
credentials" and the log on screen as used for "WPA2 Enterprise"
(see this link, scroll down and read the tutorial)
Now what am I supposed to do about that? It (router) has the latest firmware
installed (Rev-C) It works fine except the Vista.
I'm pretty sure it's a Vista issue not my router because earlier today, I
found some other dlink wireless networks around the neighborhood and tried
to log onto their SSID's and get the same prompt for credentials like as for
WPA2 Enterprise) It logs on fine to Linksys routers. The D-Link support
says it is Vista compatible...
