I have an 1100 AP that works fine for XP and 7920 phones using WPS-PSK, but NONE of the Vista machines, whether they are home or business edition can connect. The SSID is not broadcast, the error I get is out of range, yet the AP is less than 10 feet away. When I enable broadcast I get encryption errors, but nothing tells me what kind. Is there a fix for this?
My conclusion is that Vista plain downright sucks.
