We've tested MS Vista native supplicant on a SSID configure for WPA1 + WPA2 on ours WiSM. It wont work.
We've repeated the same test using a SSID configure for WPA1 and it works
First question : Why ?
Second question : What the difference between <wpa1 + wpa2> mode and WPA2 with wpa compatibility option enable. Did anyone do tests with that configuration.
