As I said, I can select for security: None, WEP, WPA2-PSK and WPAWPA2-PSK, and it only connect with WEP or None. When I use another router, a Netgear unit and one other, the camera connect for all security settings. But, my old D-Link DCS-933L camera connect without problem to the Huawei router, even with WPA2-PSK.
