I have a Dell latitude d830 running Windows 7 and a Belking 54G WiFi router which is using WPA authentication (TKIP). The problem is that Windows can detect the WLAN and gives me option to connect and even asks for the WPA key but when I enter the key and try to connect, I get message "Windows was unable to connect". I have tried connecting with other devices (a symbian mobile, iPhone, and the same machine running Windows XP pro, they all connect without any problem). Also if I turn off the WPA authentication or use WEP, it connects fine with Windows 7 but I do not want to turn it off or use WEP due to obvious reasons.
I have seen many people facing same problem with Windows 7 posting on the Internet which suggests that this is a Windows 7 issue than anything else.
Is there any solution to this problem?
The wireless adapter card is "Intel PRO Wireless 3945ABG"
