I have a very strange phenomenal using Windows 7. My router has the usual security settings WPA/WPA2, TKIP/AES and other devices are able to connect to it. However, my HP EliteBook P221 laptop, running Windows 7 is not able to connect to the wireless network. It prompts for the passphrase which I enter correctly and after that it display the message "Windows is unable to connect to xxxx". If i disable the security settings in my router, the laptop has no problem connecting to the internet. The laptop has no problem connecting to internet via the LAN cable too. Can anyone help?

Appended below is my ipconfig connected via LAN cable:
